Overview

The strangest of the Seven Summits: a 4,884 m blade of grey limestone rising out of equatorial jungle, streaked with rain, within sight of the giant Grasberg gold mine. Carstensz Pyramid (Puncak Jaya) is the highest point between the Himalaya and the Andes, and the only one of the seven that is a genuine rock climb — fixed lines up the slabby north face, a knife-edge summit ridge, and the famous gap crossed by Tyrolean traverse or a heart-stopping stride. Modern expeditions helicopter from Timika into base camp in the Yellow Valley at 4,250 m, bypassing the week-long jungle approach that some operators still offer for the committed. Summit day starts at 3 a.m. in guaranteed drizzle: five to seven hours up wet limestone on jumars, an hour of exposed ridge, and the same in reverse. The catch is access itself — permits, security and helicopter weather all wobble, and departures routinely slip by days. Patience is part of the kit list. Trips run 10 to 14 days door-to-door from Bali or Jakarta and cost £15,000 to £20,000 with helicopter access. You need solid jumar skills and comfort abseiling in the wet. It rains on the equator's glaciers nearly every day; count on climbing anyway.
