Nevado Chachani is a large extinct volcano which rises above Arequipa in southern Peru. Possibly one of the easiest 6000m peaks in the whole world to climb. The height has traditionally been given as 6057m, including by ourselves and in our guidebooks. But after several recent ascents with hand-held GPS measurements, and looking back over the SRTM data I feel a height of 6070m-6080m is more realistic. It may be that 6057m is a transcription error.

A new route up the N slopes is now more commonly used, and will certainly be better if there is much snow on the peak. Drive to a 4x4 base camp at 5050m in a col N of the peak, from here walk W (almost level) for 1½h. to an advance base camp beneath the N side of the peak. Then easily up a good zig-zag footpath to the summit, normally only a little snow at 5900m+.

We have climbed Chachani before and can organise more guided ascents of this peak. For details of how to climb Chachani and the neighbouring peaks of Misti, Ampato and Coropuna, please see our guidebooks, which are available in English, Spanish, Polish, Czech and French editions, direct from us or from all good bookshops and mountaineering shops.
