The track passes an old pipeline that fed an electricity generator used during the rail tunnel construction, then climbs steeply to the bushline. The track gains a lot of height in a short distance and is suited to people with good fitness. It is uneven and you will need to scramble over tree roots.

This track ends at the bushline as there have been multiple fatalities from inexperienced trampers/walkers falling to their deaths. The terrain is very steep with bluffs and cliff faces that you cannot see when the cloud rolls in.

Above the bushline there is no marked route. However, there are three strategically placed markers at key decision points. Make sure you note the location of these markers for your return.

Do not try to take alternative routes to the village by walking off-track in the bush or following the streams, there are steep cliffs.

In winter, there are additional hazards including snow, freezing temperatures and avalanche risk. Avalanche paths are not marked but avalanches can cross the track.

There is no track to the Mount Aicken summit

There is no track or marked route above the bushline to the top of Mount Aicken. Do not proceed beyond this point unless you are an experienced and well-equipped tramper. You need a high level of alpine tramping experience to continue to the top, including route-finding, map reading and survival skills.

Avalanche Peak is an alternative trip that does have marked routes to the summit. It also requires good weather, fitness, experience and preparation.

Above the bushline on Mount Aicken, the terrain is very steep with fall risks.The summit is a considerable distance from the end of the track. Be ready to turn back if the weather deteriorates or the terrain/navigation becomes difficult.

Start on the Devils Punchbowl Walking Track at the northern end of Arthur's Pass village, just off SH73. The turnoff is signposted 15 min up the Devils Punchbowl Walking Track.

This track is for experienced trampers

It is steep and rugged. Stay on the track by following the orange markers. Share your plans with a trusted contact.

Be prepared for delays or an unexpected night out. Carry warm and waterproof clothes, an emergency shelter, spare food, a torch with extra batteries, a distress beacon, and a fully charged mobile phone.

Walking above the bushline

If you plan to go above the bushline, you need to seek advice from Arthur’s Pass Visitor Centre staff before going on your trip. There is no marked track above the bushline.

What to take

Take a compass and map, and know how to use them. Conditions can change rapidly and you may need these for navigation if visibility deteriorates.

Do not proceed above the bushline on to the open tops unless you have sturdy footwear, a waterproof parka and spare warm clothing including warm headwear and gloves.

Weather

Check the Arthur's Pass National Park weather forecast before you go. Walking above the bushline is recommended only in good weather conditions as you need good visibility to find your way. Above the bushline you are very exposed to the severity of the mountain weather.

If it is raining, stormy or there is low cloud around the mountains, there will probably be no views above the bushline. Conditions will be unpleasant at best and dangerous at worst.

Expect snow, ice and avalanche risk in winter

This track can be covered in snow in winter. When snow is present, you will need an ice axe, crampons, an avalanche transceiver, probe and shovel, plus avalanche assessment skills.

One or more avalanche paths cross this track. Avalanches are more likely to cross the track during and after heavy snow or rain when there is already a lot of snow on the high mountains. The avalanche paths on this track are not marked.
