Huayhuash Circuit
✓ Verificada contra la agenciaA full loop around one of the most concentrated ice ranges on earth — Yerupajá (6,635m), Siula Grande (6,344m) and Jirishanca (6,094m) ringed by a circuit that crosses eight passes between 4,500m and 5,000m and almost never drops below 4,000m. The walking is non-technical; the altitude is what makes it serious. Every night is a camp, every day is a pass, and the range is remote enough that evacuation means a horse and a long day.

Safe window: May to September. MINCETUR's national tourist-resource inventory gives "mayo a septiembre" as the recommended season on every Huayhuash record it holds (Llamac/Pocpa, Pacllon/Jahuacocha, Queropalca, Nevado Yerupaja). NOT safe October to April. SERNANP records precipitation from September to mid-April, and night temperatures below 0 C above 4,000 m in every month. The wet season closes the road in, not only the trail: on 1 March 2026 the Municipalidad Distrital de Paccllon reported landslides, collapses and rain erosion on the Pacllon-Chiquian (AN-1271) and Llamac (AN-1263) vecinal roads and on the Pacllon-Cura Pampan track into the Cordillera Huayhuash, and D.S. N.o 025-2026-PCM placed the district under a state of emergency for imminent danger from intense rainfall. The same municipality had to rehabilitate the Pacllon-Cruz Pampa track in April 2026 and maintain it again in July 2026, so treat the access track as damaged by default at the end of each wet season. Control posts also close before dark (Huanuco sector 06:00-18:00; Llamac/Pocpa and Pacllon 08:00-14:00), so an October-April arrival can find both road and gate shut.
- ▲Altitude, the primary killer: the circuit sleeps 8 to 12 consecutive nights above 4,000 m and crosses passes to about 5,010 m, so HAPE and HACE are the realistic causes of death. The Huanuco protocol (Art. 12.5) names altitude first among the risks that make guides mandatory; Andina requires a minimum of two acclimatization days before starting.
- ▲Hypothermia: SERNANP records that temperatures fall below 0 C at night above 4,000 m, in every season, and every camp on the circuit is above that line.
- ▲Geographic isolation: no road touches the circuit between Cuartel Wain and the exit passes. The protocol (Art. 12.5) cites aislamiento geografico explicitly. Evacuation is on foot or horseback to a track head, then hours on an unpaved road, so a stable patient can be a day or more from a clinic.
- ▲Wet-season landslides and road collapse on the access routes: the Pacllon-Chiquian (AN-1271), Llamac (AN-1263) and Pacllon-Cura Pampan tracks were cut by landslides and rain erosion in March 2026, with the district declared in a state of emergency by D.S. 025-2026-PCM. Trekkers can be trapped on the wrong side of a slide.
- ▲Snow, storm and whiteout on the high passes (Cacanampunta, Rondoy, Trapecio, Arag/Portachuelo) outside the May-September window, when SERNANP records precipitation from September to mid-April.
- ▲Limited visibility after dark at altitude, cited by the protocol (Art. 13.2) as the reason entry and registration close in the evening; night movement on the passes is not sanctioned.
- ▲Being refused entry or expelled mid-route: control posts turn back anyone without a DIRCETUR-registered guide and a registered agency, and Art. 21 permits an on-the-spot acta, immediate removal of the visitor or group, and a temporary or permanent ban from the cordillera. A party that starts unregistered can be stopped days in, at altitude, with no road out.
Independent trekking on this circuit is prohibited as of 2026. Ordenanza Municipal N.o 005-2026-MPL/CM (Municipalidad Provincial de Lauricocha, published 14 May 2026) approved the Protocolo de Uso Turistico Sostenible de la Cordillera Huayhuash for the Huanuco sector, co-branded by DIRCETUR Huanuco. Art. 12.4 states it directly: "Queda prohibido el ingreso de visitantes de manera independiente o no organizada (mochileros)" - entry by independent or unorganised visitors is prohibited, with access permitted only under the stated conditions, to guarantee visitor safety and control of entries. Every classic-circuit itinerary crosses the Huanuco sector (Cacanampunta, Mitucocha, Carhuacocha, Campamento Huayhuash and both exit passes, Trapecio and Arag, are inside it), so the rule binds the whole route. This is why guide is required-legal rather than required-safety. One correction to the brief's framing. Huayhuash is not a national park, but it is not purely private communal land either. It is the Zona Reservada Cordillera Huayhuash, created by Resolucion Ministerial N.o 1173-2002-AG on 20 December 2002, 67,589.76 ha across Bolognesi (Ancash), Lauricocha (Huanuco) and Cajatambo (Lima). SERNANP still lists it as one of Peru's eight Zonas Reservadas - a provisional protected-area category awaiting definitive categorisation - and Art. 13 of the Ley de Areas Naturales Protegidas plus Art. 59.2 of its reglamento place Zonas Reservadas inside SINANPE. In practice the layers are: SERNANP holds the conservation status but does not staff or charge at the trail; the province and DIRCETUR write the rules; the comunidades campesinas administer, control and monitor entry and take the money (Protocolo Art. 5). So a government agency does document this route, contrary to the brief's fallback assumption. No equivalent protocol has been published for the Ancash sector (Bolognesi, Pacllon, Llamac, Pocpa) or the Lima sector (Cajatambo, Huayllapa, Uramasa). I searched gob.pe and found only the Lauricocha instrument. Treat the guide requirement as applying to the whole circuit, both because the route crosses Huanuco and because that is the conservative reading. On the Ancash side MINCETUR records the Asociacion de Porteadores y Arrieros de Llamac as administrator since 2012, so an arriero is in practice the local counterpart there. On the Alpine variant: no Peruvian authority documents it. Andina's 30 July 2026 guide lists four official circuits - Clasico, Achalau Huayhuash, Huayhuash-Raura, Shumaq Huayhuash - and the Alpine Circuit is not one of them. The Huanuco protocol authorises named tramos and variants and requires visitors to travel only on them (Art. 14.1), with camping outside authorised areas permitted only for mountaineering parties. Every Alpine Circuit description I could find is commercial-operator or blog material. Treat it as unpermitted off-route travel until an authority publishes otherwise, and do not publish or sell it as a route. Regional media reported around 20 February 2026 that MINCETUR met the administering communities and agreed to bar mochileros and unaccredited agencies. I could not find a government publication of that meeting, so I am not relying on it; the May 2026 ordinance is the published, verifiable version of the same rule. Gap worth naming: I found no authority publication on crime or robbery risk on the circuit. That is an absence of evidence, not an all-clear. Difficulty is set to mountaineering on altitude alone. The walking is non-technical on established community trails, with no rope and no glacier travel, and MINCETUR and Andina both call the classic circuit moderate to difficult. But the circuit sleeps 8 to 12 nights above 4,000 m and crosses roughly 5,010 m, and altitude is what kills people here, so the more dangerous enum value is the honest one. Equipment is set to traction, not glacier: trekking poles, microspikes for snow lying on the passes, and a sleeping system rated for sub-zero nights at every camp. Anyone buying rope and crampons for the standard circuit has misread this; anyone arriving with a two-season bag and no acclimatization plan is in real danger. VERIFICATION NOTE: the agency research pass is complete and cited, but the independent adversarial re-check had not run when this shipped (quota). This entry is view-only and enables no download, so it is fail-safe either way; re-run the adversarial pass before any change that would relax a field. PERMITS & FEES — There is no national-park ticket. SERNANP does not staff or sell entry to the Zona Reservada. Each comunidad campesina runs its own control post, registers you, charges its own fee in cash soles and issues a receipt. Receipt: personal and non-transferable, proves payment for that sector, must be kept for the whole stay and produced at every subsequent control post (Protocolo Arts. 11.1-11.4). Collection is deliberately decentralised because different communities administer different sectors. Mandatory registration (Art. 12): identity document (original DNI for Peruvians; passport, carne de extranjeria or cedula diplomatica for foreigners), the route you will follow, and your estimated duration. The registration is valid only for the declared route and period, and does not permit re-entry. Mandatory guide and agency (Arts. 12.4, 15.1-15.3): every group must be accompanied by an official tourism guide registered with the competent Direccion Regional de Comercio Exterior y Turismo, who must present his guide carnet at the control post; the travel agency must be listed in the Directorio Nacional de Prestadores de Servicios Turisticos and identify itself at the post with the group's details. Maximum ten people per guide is recommended; above ten, one additional guide per ten participants is obligatory, plus guide assistants, accredited at the control posts. Fees recorded in MINCETUR's tourist-resource inventory, charged separately by each community: Llamac/Pocpa S/20; Pacllon for Laguna Jahuacocha S/20; Queropalca S/40 foreigners / S/30 nationals, plus Quishuarcancha campground S/30 foreigners / S/25 nationals; Huayllapa for Mirador San Antonio S/50 foreigners / S/25 nationals; Uramasa for Laguna Viconga and Banos de Gunoc S/30 foreigners / S/15 nationals (under-10s free). MINCETUR ficha 2904 additionally records communities charging between S/10 and S/30 per foreign trekker per campsite. Carry substantially more cash in small soles than the sum of the published figures: the inventory is not a complete list of control posts and the amounts are set community by community. Control-post hours: Huanuco sector 06:00-18:00, Monday to Sunday, referential, with late arrivals regularised the following day (Art. 13.1). Llamac/Pocpa and Pacllon 08:00-14:00. Queropalca 05:00-17:00. Mirador San Antonio and Laguna Viconga 07:00-17:00. Banos de Gunoc 06:00-18:00. STAGES — The authorities publish two different framings of the loop, and no single authority publishes a day-by-day camp list for the whole circuit. SERNANP (protected-area record): the full circumnavigation is 165-180 km and takes 12 to 18 days, crossing five high passes averaging 4,300 m. Shorter routes of 2 to 12 days exist, all walked above 4,000 m. Andina, Peru's state news agency, 30 July 2026: the "Circuito clasico" is 12 days, about 120 km, from Cuartel Wain to Llamac, elevation range 3,300-5,010 m, moderate to difficult, with a minimum of two acclimatization days before starting. Three other official circuits are listed: Achalau Huayhuash (8 days, 103 km, 3,300-5,040 m, using Paso Trapecio as a shortcut), Huayhuash-Raura (9 days, about 70 km, Llamac to Surasaca-Churin, 3,300-4,800 m) and Shumaq Huayhuash (10 days, 105 km, 3,300-5,000 m). The Huanuco-sector protocol (Ordenanza Municipal 005-2026-MPL/CM, Art. 9-10) is the only authority that names legs, control posts and overnight places, for its own jurisdiction: - Control posts (Huanuco side, three): Puesto de Control Mitucocha-Queropalca; Campamento de Quishuarcancha; Campamento Huayhuash-Tupac Amaru. - Tramo 1: Cuartel Wain trailhead over Paso Cacanampunta down to Campamento Mitucocha. - Tramo 2: Mitucocha to Campamento Carhuacocha, three authorised variants. 2A direct. 2B via Mirador Jirishanca then Mirador Norte (TAM). 2C via Mirador Ninacocha. - Tramo 3: Campamento Quishuarcancha to Campamento Huayhuash, two authorised variants. 3A via Laguna Carhuacocha, Laguna Gangrajanca, Laguna Siula, Laguna Quesillacocha and the Mirador Tres Lagunas. 3B skirting five lakes. - Tramo 4 (exit): from Campamento Huayhuash, two authorised variants. 4A over Paso Arag (Portachuelo) on the Huanuco-Lima boundary to Laguna Viconga (sector Uramasa) and Campamento Gunoc. 4B over Paso Trapecio on the same boundary. Overnight and high-point altitudes recorded by MINCETUR: Laguna Jahuacocha 4,053 m, Banos Termales de Gunoc 4,354 m, Laguna Viconga 4,532 m, Mirador San Antonio 5,002 m (Huayllapa side, the documented high point). Camping is permitted only in community-authorised areas; camping outside them is allowed only for mountaineering parties on climbing routes (Protocolo Art. 14.1).
