Mount Tasman Mountain

Mount Tasman is the second-highest mountain in New Zealand, located in the Southern Alps within Aoraki/Mount Cook National Park on the South Island. It is a major alpine peak closely associated with New Zealand’s highest mountain, Aoraki/Mount Cook.

The mountain’s slopes feed large glaciers and present long, glaciated routes; the eastern slopes in particular give rise to the Tasman Glacier. Climbers approach via glacier travel and technical alpine routes rather than simple walking tracks.

Mount Tasman and its surrounding glaciers are integral parts of the national park’s high-alpine landscape and are important for mountaineering and glaciological study. Glacial retreat has been observed in the area, affecting approach routes and glacier morphology.

The peak sits in the central Southern Alps on the boundary of the West Coast region and the Aoraki/Mount Cook National Park, accessible from Mount Cook Village to the north by backcountry approaches and mountaineering routes.

• Second-highest peak and park location: Ranks as New Zealand’s second-highest named summit and lies within Aoraki/Mount Cook National Park, a protected alpine area with extensive glaciers.
• Climbing and glacier conditions: Alpine routes to the summit require glacier travel and technical climbing experience; conditions are heavily glaciated and changeable.

What to See#

• Tasman Glacier: A large glacier that drains the eastern slopes of the peak and is New Zealand’s longest glacier, flowing down from the high alpine cirques toward the Tasman Valley.

Mount Tasman sits in the Southern Alps near Aoraki/Mount Cook National Park. Most approaches begin from Aoraki/Mt Cook Village; access is by road from Christchurch (about 4-5 hours’ drive). For serious climbs, parties stage from the mountain village and consider helicopter support to reduce long glacier approaches.

• Combine a Tasman attempt with a Mount Cook base; many parties use Aoraki/Mount Cook village as a staging point.
• If planning a glacier route, carry appropriate crevasse-rescue equipment and consider hiring a certified mountain guide-glaciated approaches are long and remote.
• Heli-assisted climbs reduce approach time but require booking well in advance and favorable weather.
