Stage 4 of the Huayhuash Circuit covers 11.0 km from Huayhuash to Viconga, with 516 m of ascent and 477 m of descent. The highest point is 4,771 m. Allow about 5 hours of walking, plus breaks.
Distance, climb and elevation come from the Outest route data. Difficulty and time are estimates from distance and climb; your pace will vary with heat, pack weight and photo stops.
Natural hot-spring pools beside the Viconga campsite, the only place on the circuit where you can wash properly. A small kiosk next to them is mapped on OpenStreetMap; opening depends on the season, so carry cash and do not count on it.
Aguas Termales de Viconga
Campsite at about 4,400 m below Viconga lake, next to the community hot springs, about 0.4 km from the main path to Punta Cuyoc. The Viconga visit is charged by Uramaza (S/30 in 2026) and camping by Huayllapa; a small extra fee may be asked for the pools.
Checked online in October 2026. Places marked "not confirmed by the operator" are listed on OpenStreetMap or in guides but could not be checked on an official page. On the Huayhuash Circuit you camp at the community campsites; each community collects a cash fee in soles for its land and camps, so keep every ticket. Since February 2026 the communities say they no longer admit unguided trekkers: go with a registered guide or arriero.
Emergency: call 105 (police, Alta Montaña) or 106 (ambulance). No mountain rescue. Emergency & health guide
