Lenin Peak Razdelnaya Route & West Ridge
The Razdelnaya Route via the North Face and West Ridge is the classic standard route on Lenin Peak (7,134 m). Starting from the Achik-Tash Base Camp (3,600 m), the route navigates the crevassed Lenin Glacier to Camp 2 (5,300 m), scales the steep snow slopes to Razdelnaya Peak (6,148 m) for Camp 3, and makes a sustained 1,000-metre summit push along the exposed West Ridge to 7,134 metres.
