Cholatse stands between Gokyo and the Khumbu valley, and its north face is one of the great Himalayan test-pieces — not what we climb. The south-west ridge is the standard line and it is still a serious alpine route: steep snow and ice, rock steps, two committing camps and enough exposure that the descent needs as much planning as the ascent. It sits under an expedition-peak permit rather than a trekking-peak one, which is the honest reflection of what it asks. For an experienced alpinist who wants a hard Khumbu summit without the cost and duration of an 8,000 m permit, there are few better objectives in Nepal.
TerraBlaze runs this climb end to end: the NMA permit and park fees, the trek in, a fully staffed base camp, a licensed climbing guide and a climbing Sherpa on summit day, fixed rope on the steep ground and an evacuation plan filed before you land. You bring the fitness — we handle everything else.
