Route Guide: Northern Crossing of the Tararuas

By Ian fisk

This is not the usual Northern Crossing from Levin to The Pines via Mitre Flats Hut.

Rather it exits via Baldy, Atiwhakatu Hut and the Holdsworth road end. The last day would be very long and should be broken at Atiwhakatu Hut.

Access

A taxi from Levin will normally drop you at the narrow "pipe bridge" on Gladstone Road across the Ohau River - a couple of drivers will take you all the way to the road end.

Pipe Bridge - Te Matawai Hut

The road end is only 10 minutes walking up the farm access road and has a triangular patch of grass with a couple of picnic tables, a toilet and an intentions book (under the cover on the park sign). Don't go through the gates past the farmhouse, but cross the stile just inside the gates. The path leads a few metres to a farm track going gently downhill and across a paddock to another stile (electric fence so take care). The farmer usually runs cattle in the paddocks along the route - look out for the obvious by-product. Over the stile, the path rises slightly to pass a rock outcrop with a plaque on it about the Levin Waiopehu Tramping Club. A small stream is crossed and then a river terrace takes you to another electric fence (just a strand of wire) with a squeeze to one side. A last stile is crossed to enter the bush edge about 10 minutes from the road end.

Just inside the bush there is a junction of tracks with signs up on the trees. The track climbing up the slopes to the right goes to Waiopehu Hut which is a good (drier) alternative route to Te Matawai if the river is high. The track to the Ohau Shelter goes straight ahead. It takes about an hour to get to the Blackwater Stream (with a high swing bridge) and another 5 minutes to the Ohau Shelter (the partially dismantled remains of a hut). The walking is quite level along a good track with a few glimpses of the river below - the crossing of an old slip about halfway gives a good view. There is a grassy patch next to the shelter that provides a nice spot for a break.

The track continues past the hut (slightly muddy but plenty of stepping stones) and down to the river. On the way you pass Ozzies Track which provides another access route to the junction of the North and South Ohau Rivers. While it starts off as a good track, it soon becomes a narrow sidle along the contours with a nasty rock outcrop to navigate at the end. It takes the about the same time as following the river. The main track joins the river at a large gravel bank. It is wise to note the entry point in case you return back down the river.

The walk up the river to the junction is mostly on bouldery banks with a number of crossings. At the end of a dry summer, I found all of the crossings easy (my knees remained quite dry). A couple of the crossings have swift water even in moderate flow and you should expect them to be around knee deep. The usual time to the junction is 40 minutes with a further 80 minutes up from the junction to the first hut. Ozzies Track emerges about 25 metres downstream. From the junction, a nice little gorge is quickly passed though to more open terrain - look out for a cute mountain cataract on your right. Half an hour of easy river travelling will take you into the upper gorge - much narrower than the lower one and more interesting. The river bed is rougher to travel with one diversion up the bank for a few minutes to avoid a deep pool. One pool that you cannot avoid is situated near the middle of the gorge - there are vertical walls on either side. Normally this is a swim in chest-high, chilly water for a few metres onto a rock ledge followed by a scramble over rocks to bypass a small waterfall. The rest of the gorge features a couple of thigh-deep crossings before its end. After the narrow confines of the gorge, there is a real feeling of space for the rest of the walk to the hut. There are even a couple of river flats suitable for camping on the way. You know that the hut is near when you see a "Road Works Ahead" sign on an outcrop of rock in the middle of the river. Note that the South Ohau Hut (sleeps 12) is accessed from about 20 metres up Butcher Creek (on your right) rather than straight from the river.

The hut is well situated for a very relaxed day's walking from the road end but can be reached within 4 hours at any faster pace. This gives the option of going straight on up to Te Matawai Hut up the Yeates Track.

The initial section of the Yeates Track is commonly known as the Yeates 600 for the steep 600 feet (182 metres) climbed. It tries to zigzag up the slope but there are still a couple of big steps to haul yourself up. Forty minutes brings an abruptly level patch marking the easing of the slope. Another 40 minutes of gentler climbing over various bumps brings the well-marked junction with the track from the Butcher Saddle. Te Matawai Hut (sleeps 30) is 35 minutes from the junction - the track firstly dips down a bit and then climbs steadily. Keep an eye out for a metal tag on a tree on the right about halfway up - this marks a route down to the headwaters of the Otaki River (an interesting alternative if conditions do not permit travel on the tops). Normally allow about 2 hours between huts.

The hut is big and roomy with a clear view of the ridge leading up to Pukematawai (which hides Arete from the hut). Triangle Knob and Mt Dundas can be seen beyond the ridge. The panorama is even better from the rise above the helicopter pad a few minutes back along the track. From Pukematawai, the Main Range makes its undulating way to the south. The first prominent bump along the range is Butcher Knob with the sharp peak of Lancaster just showing behind it. A long spur rising from the Otaki River valley points to the bald top of Kelleher.

Over Arete to Tarn Ridge Hut

The track starts immediately outside the hut's front door and goes past the toilet into a dip, passing the old hut site. There is plenty of mud to endure while crossing the dip but the track becomes drier as it climbs up a small knob. At the top of the knob (15 minutes from the hut), there is the obvious turn-off down to the Girdlestone Saddle. The rest of the ridge is steady climbing with a few tiny steep bits and a fairly overgrown track until higher up. On a fine day, the hut is visible all the way to Pukematawai giving a good indication of progress.

The main range is joined just a couple of minutes from the top - there is an unobtrusive junction with the route south along the tops. If you find yourself coming down from Pukematawai, note that the main range ridge continues straight ahead while the ridge to Te Matawai Hut drops to the NW. On a clear day, the views from here and Arete are tremendous. The summit of Arete is an easy 20 minutes away over a small saddle (135 minutes from the hut).

With good visibility, you can head directly to the Northern Crossing route from the summit but don't even think about it in cloud unless you want to experience the hanging valley and waterfalls on the south face of Arete. The better route is to head east along the ridge towards Dundas and Bannister for 6 minutes where a tiny rocky notch crosses the ridge. There is the first of an intermittent series of iron poles in the notch. Turn south across the slopes and drop to the Arete Tarn and Bench, along a stony gully for part of the way. The tarn is a reliable source of water and a good excuse for lunch. An option is to visit the Arete Biv by dropping east from the tarn to a gully and following this for 150 metres north to the biv. Fresh water can be found at a spring about 75 metres down the watercourse to the north of the biv.

The Northern Crossing route is regained by heading south from the tarn. A gentle climb up to point 1385 is followed by a short ridge walk to a climbing sidle along the ridge to Lancaster (60 minutes from Arete, 1504m high). At the highest point of the sidle is a mandatory diversion in clear weather. Drop your packs and head along the nicely sharp ridge up to Lancaster for the best viewpoint in the park (10 minutes to the top). The view to the north is Pukematawai and Arete of course with the sharp ridges of Bannister over the ridge to the NE. To the west, you can peek over the main range and glimpse the speck that is Te Matawai Hut. At your feet to the south are the headwaters of the Waiohine River and to the north there is the Park River valley - the wide U-shaped valley is thought by many to be the only glacial valley in the park. The lightly padded track over Lancaster leads along the Carkeek Ridge via a hut to Park Forks where the Park River joins the Waiohine River (the longest in the park). Beyond the forks looms Mt Crawford (1462m) and the rest of the main range. The rest of the day's route to and over Tarn Ridge lies to the east (the new hut is actually over a couple of bumps from the south end of the level Tarn Ridge) with the Waiohine Pinnacles looking suitably rugged. Further south, Girdlestone marks the point where the ridge splits to go to Mitre (east) and Holdsworth (west). Over Tarn Ridge, another level ridge (Table Ridge) extends north from Brocket (near Mitre) to drop to the Waingawa River at Cow Creek Hut.

Having fed your eyes and soul, return to your packs and travel a few minutes south to an iron standard at the head of the Waiohine Pinnacles. This marks a useful escape route down to Arete Forks. There are only a couple of pinnacles to cross with a number of sharp bumps beyond them. The well-defined route over the pinnacles needs care only in snow or wind. The second pinnacle is geologically interesting since it is an intrusion of red volcanic rock in the usual grey rocks of the ridge. The level start to Tarn Ridge is quickly reached.

After the level walking, the trail dips SE and climbs over a small bump and a saddle to a knob and Blatchfords Cross - a wooden cross commemorating a deer hunter who died in the ranges and is buried alongside the track. Tarn Ridge Hut (sleeps 16) is in a small basin to the east of the ridge between the cross and point 1371 - there is a signpost on the track pointing the 30 metres down to the hut.

Girdlestone, the Kings, Baldy, Atiwhakatu Hut and out

The day starts with a steady climb up the ridge from the hut to the junction with Dorset Ridge (joining from the SW) - 20 minutes from the hut. There is a large scenic tarn on the south side of Dorset Ridge. In another 10 minutes, the Girdlestone Pinnacle is reached as the ridge tends to the east (a bit of a scramble up but no great difficulty). The pinnacle can be sidled to the north in winter. Within an hour from the hut, you reach the large survey beacon on the top of Girdlestone at a height of 1547 metres. This is another spot with great views, especially north to Bannister. The twin peaks of Mitre (at 1571 metres, it is the highest point in the park) and Peggy's Peak (1545m) are prominent to the east.

From Girdlestone, Mitre is about 60 minutes away to the east with the descent to Mitre Flats Hut (sleeps 20) taking another 2 hours. This is the usual exit route (another 3 hours to the road end). The exit via the Holdsworth road end starts by backtracking 30 metres to the junction with the ridge to Adkin. The southwards descent is along a rocky and sharp ridge with the valley of the South Mitre Stream opening up on the east. On the way down, you should pause to look into the valley and admire the 20 metres of waterfalls in the upper basin - to be avoided by a sidle to the scree gully draining Mitre if you have to escape down the stream (quite rough going with a couple more waterfalls lower down). In the saddle before Adkin, there are a couple of reliable tarns encouraging a morning break.

Beyond the saddle, the track crosses over a small bump (starting to the west of the tarns) and then climbs up to Adkin (1460m, an hour from Girdlestone). There is a bit of a climb up to North King (1535m) but no problems following the track. Middle King (1521m) is really just a knob in the level ridge between the other 2 Kings but has a nice little (and shallow) tarn right next to the track.

South King (1531m, iron tube on the top) is not impressive but provides a point to evaluate the track as it goes on over the Broken Axe Pinnacles to McGregor. The route can be extended to Jumbo Hut (3-4 hours away) in fine weather.

The turn-off to Baldy is a few minutes down from South King and is marked by a cairn on a small knob. The track starts off a bit indistinctly but soon defines itself for a rapid descent along a tussock spur (about 200m dropped to the saddle before Baldy). Baldy's flat eroded summit (1325m) is reached by a gentle climb from the saddle. The tussocky hummocks around the sandy top give good seats for a bit of a rest. Head east from the north side of the tussock surrounding the summit for a few metres until you join the spur descending NE from Baldy. There is a cairn marking the Barton Track (to Mitre Flats) turn-off less than 10 minutes down the spur where it turns more to the south. It is easy to follow with plenty of cairns, especially at the bush edge (20 minutes from Baldy). In the bush, the track is not well padded but is adequately marked for the hour or so down to Atiwhakatu Saddle. The stream is 10 minutes down from the saddle down a track that is steeper than it looks on the map.

The Atiwhakatu Stream is crossed by a good swingbridge. The track down to the Atiwhakatu Hut (sleeps 10) takes about an hour and is in fairly good condition except for a couple of slips. The first is easily crossed with a climb up and along its face and then down a rocky gully to the stream. The second slip is a much harder proposition with a scramble down a clay bank, squeeze under a fallen tree and then slippery soil to cross. A wetter option is to backtrack a little and break out of the bush to the stream. A few crossings of the stream take you through a flood channel on the true left and back to the track by crossing to a gravel bank on the true right and clambering onto a flat which the path crosses. The only other problem you may find is that the track is a bit indistinct where it meets the northerly track down from Jumbo - it looks like it goes into a marshy river flat (with the junction signpost on a bank) however the bank is better gained by an overgrown fork just before the flats.

The rest of the track to the Holdsworth road end is wide (except where it crosses one small slip), mostly gravelled and level. All the major side-streams are bridged - one with a tree. There are nice views back up the valley from the sparsely treed sections above the minor gorge before Donnelly Flat.




Mt Ruapehu Routes

Location: 39.28 S, 175.57 E
Elevation: 9,174 feet (2,797 m)

Last Updated: 11 September 2000

Ruapehu, the tallest mountain on the North Island, is a massive andesite stratovolcano. The currently active vent is an acidic crater lake near its summit. The volcano has a volume of 110 cubic km and the surrounding ring plain has a similar volume. Photo is looking south across the flank of Ngauruhoe to the September, 27, 1995 eruption of Ruapehu.

Simplified geologic map of Ruapehu. The volcano began to form more than 120,000 years ago. The Te Herenga Formation is made of lava flows, breccia, plugs, and dikes. It is exposed on the northwest side of the mountain. The Wahianoa Formation is made of lava flows, breccia, and lahars and is exposed on the southeast side of Ruapehu. The Mangawhero Formation form the resent-day high peaks and main cones of Ruapehu. The formation consists of lava and pyroclastic deposits. The Whakapapa Formation is mostly younger than the most recent glacial period (about 15,000 years ago) and is made of block lavas, breccias, and pyroclastic material that erupted from 6 vents. Crosses show the locations of vents active in the last 50,000 years. From Cole (1990).

Mt Ruapehu from the Rangipo Desert
In winter, Mt Ruapehu is New Zealand's most used mountain for the purposes of mountaineering. Yet no guidebook exists. It may not be long before this situation is rectified, but until then this page may be the best source of information. As a guide it is incomplete since it is largely based my own experience on the mountain. Therefore I am very open to readers challenging what is written here or adding to it in either depth or scope. Email [email protected].

The Beginner's Playground

 

Ruapehu Map
On fine winter days, dozens of alpine trampers make the trek to the Summit Plateau (2600m) for views of the Crater Lake and the surrounding peaks. The inexperienced can learn how to walk with crampons and self arrest with an ice axe without encountering steep slopes or exposed heights. Following skifields lower on the mountain aids navigation. No ropes or climbing is necessary.
   As the tramper becomes more confident with axe and crampons a range of ridges and peaks are possible to explore. Perhaps the only peak out of possibility would be Girdlestone. A variety of routes to the Plateau open up. Camping on the Plateau in good conditions is a wonderful alpine experience.
   Those trampers wishing to make the transition to more serious climbing can learn the rope and climbing skills on steeper faces and ridges with a degree of safety. The exposure is relatively low and routes can usually quickly be abandoned in a single pitch. It is just a matter of selecting a slope that looks right for you.

 

Access and Huts

Despite Mt Ruapehu being a giant mountain, climbers will not be lonely since everyone uses the skifields as access.

Whakapapa is a well trodden access route. Bruce Road can be driven or hitched from Whakapapa Village to Iwikau Village (1600m). Iwikau consists of the Whakapapa Skifield base and many mountain club huts (mostly ski clubs) but nothing else. The lifts can be taken to Knoll Ridge Cafe (2000m). Otherwise follow the line of huts and snow poles that lead to much the same place. From here climbers can access the Pinnacles or climb to the Summit Plateau.

The New Zealand Alpine Club has a hut on Delta Corner (slightly west of Knoll Ridge Cafe) but it isn't open to the public like DoC huts - that is, it has to be booked and the door has a combination. But you can always turn up and see if there's a bunk for the night as long as you pay the fee. It has an emergency foyer.

Dome Hut is an emergency shelter on Dome Ridge (2670m). It isn't supposed to be used for overnight camping and isn't that luxurious anyway. There is a chimney for access if the door is blocked.

The Summit Plateau is a good camp site if you know where to go. Don't leave a camp site in the middle of the Plateau if there is a chance the weather will be anything but perfect. In a white-out you'll have no chance of locating your gear again. The best areas sheltered from the wind are around the Cathedral Rocks. This is also the only place you are likely to find deep snow for caves since the winds on the Plateau are strong.

Turoa is also frequently used. Mountain Road ascends from Ohakune to the Turoa skifield (1600m). Lifts can be taken to a high cafe (2000m) or the frozen waterfall to the south east of the skifield (seen from the lifts). The Turoa side is relatively free of bluffs or any navigational requirements so long as you can see where you're going. Access onto the Plateau is difficult for beginners due to steeper slopes.

Mangaturu Shelter (2300m) is an emergency shelter north of the upper skifield. I've never been inside but I imagine it's very similar to Dome Shelter.

Rangipo is the third access route. A four wheel drive track leads from State Highway 1 (Desert Road) to Tukino Skifield (a small club field). At time of writing (2003) most people manage to get their 2-wheel drives to the end of the road. The NZ Alpine Club has a club hut at 2100m. The Whangaehu Glacier provides easy access to the Plateau.

Route Grades

Please note:

 

  • This is aimed at beginners and the experienced and info is given in a depth relevant to those a route is suitable for.
  • Technical routes often require the climber to stay close to the described line in order to achieve the grade given.
  • An approximation of the New Zealand alpine grading system is used. It is difficult (pointless?) to grade the more technical climbs since they are short in length. As a rough guide,

    Alpine Tramp: requires crampons and axe to be carried. Suitable for those with reasonably strong tramping experience. Self arrest should be practised before venturing high on the mountain. Navigation skills are required with some understanding of avalanches (stay off lee slopes, loaded basins and during and after large snow falls - if you don't understand this then talk to the Department of Conservation at Whakapapa Village before starting out). No steep slopes or exposed walking. If you don't know what clothing and supplies to take then you are not experienced enough to do these tramps. This is not at all like doing tourist treks up the Routeburn or 'Around the Mountain' - it is entry level mountaineering.

    Grade 0: the routes are a little steeper than those rated as an alpine tramp and may be exposed. Beginners will feel a touch nervous. Self arrest practice is essential. No climbing involved.

    Grade 1: May require front pointing with crampons if icy or good French technique if wearing leathers or step kicking if a snow route. Rope not necessary unless leader is taking a beginner.

    Grade 2: A rope might be used on rock and ice routes by the less confident. Snow routes don't tend to achieve this grade.

    Grade T: Technical pitched climbing on mixed routes or steep ice. Since the routes are short there isn't much point in assigning more precise alpine grades.

    Routes to the Summit Plateau

    Most alpine trampers wish to gain the spectacular Summit Plateau. Climbers can use the peaks surrounding the Plateau. Most of the routes follow skifields at lower altitudes. Skifield access is discussed above.

     

    The Summit Plateau from Tahurangi
    The easiest routes are from the Whakapapa Skifield. From Knoll Ridge Cafe walk up next to the Knoll Ridge T-Bar before finding an easy crossing onto Restful Ridge. Restful Ridge is easy angled and pleasantly off the skifield. The tricky part is turning left towards the top of the ridge to pass through a narrow gully called 'The Notch'. On your first attempt you are likely to go too far right of The Notch. The Notch is a gap in a long wall overlooking the Plateau. It allows the tramper to walk straight onto the Plateau. Most trampers like to walk along the top of the wall (Dome Ridge) to the right of The Notch until they arrive at Dome Shelter overlooking the Crater Lake.
     Alternatively the tramper can continue the full length of Knoll Ridge and then take the broad northern gully (to the left of Restful Ridge) to The Notch. This is just as easy as Restful Ridge but is not as scenic, has skiers to contend with along Knoll Ridge and the gully can be avalanche terrain (if inexperienced with reading snow stability stick to Restful Ridge). Grade: Tramp
      The most rewarding route to the upper mountain from the cafe crosses the Te Heu Heu ski run then gains the upper Pinnacle Ridge (or alternatively the gully just to the right looking up the mountain). The ridge gives fantastic views of Mt Ngaruhoe and Mt Tongariro and finishes between the peaks of Te Heu Heu and Tukino. To access the Plateau traverse the Te Heu Heu Ridge to the right until reaching the Notch. This is a more exposed route than those given above. Pinnacle Ridge is easiest when completely snow covered during mid winter. Grade: 0

    Routes on the Peaks

    Tahurangi (2797m)

    Girdlestone Ridge running from
    Girdlestone to Tahurangi

    North face. A number of lines offer different challenges. I've only climbed it once and there was quite a bit of falling ice once the sun was on it. Grade: 2+ to T

     

    West ridge. There are two ways of accessing the west ridge, which curves around to the north, from the Summit Plateau. One is to start at the foot of the ridge on the western side of the Plateau and sidle the outer side of the ridge. The major obstacle is an overhanging ice cliff which can be avoided by a low sidle. The more direct route is to pass the Crater Lake on its western bank and climb the slope to the west of the North Face to an obvious col. Then sidle the west ridge to the summit. Grade: 1+

    South-west aspect. This is the most common route and is climbed directly above the Turoa skifield. The featureless slope gradually steepens and builds exposure without the climber really noticing. Maybe the easiest variation is keeping on the vague Skyline Ridge to the summit. Somewhat dangerous for the beginner if in icy condition. Grade: 1

    Eastern Flank and Mitre Ridge. Straight forward climbing. The Ridge to Mitre Peak is very elegant. Grade 1+ Southern Aspects and Girdlestone Ridge. Technical routes can be picked out on this side of the mountain especially through the ice cliffs under Tahurangi. The Girdlestone to Tahurangi traverse would be a challenge if the climber stays exactly on the ridge. In reality you'll probably prefer to pick and choose parts of the ridge that offer good climbing for your ability. Grade 1+ to T
