The Mountain ranges of Arthur's Pass National Park are the most accessible in New Zealand, being located aside the main road/rail corridor traversing the Southern Alps between Christchurch and the West Coast. Terrain within the park varies considerably from low scree hills to heavily glaciated peaks and steep face routes. Climbing within Arthur's Pass National Park could be considered to epitomise all that is mountaineering, with the 'approach' forming a substantial component of the actual climb, and the luxury of aircraft being appealingly devoid from the park. This guide covers broadly an outline of the standard routes on the peaks of both the National Park and the adjacent Craigieburn Forest Park. Additional sections on huts, history, alpine rock, ski touring and potential ice climbs create an invaluable resource for any climber visiting the region. A total of over 280 routes are listed in this guidebook, and are an indication of the range of climbing opportunities provided by this area. While many of the earlier ascents involved traverses of often delicate ridges, the greatest potential for new routes may be in face climbs which have been overlooked until now.
