Trek the Huayhuash Circuit with Licensed Mountain Guides from Huaraz

Huayhuash Circuit offers three guided packages, all with licensed local guides, full meals, mules and community entry fees included: the 4-day Huayhuash Mini Trek, built around Laguna Jahuacocha; the 8-day Huayhuash Trek — our most popular, covering the full circuit including the Three Lakes viewpoint and Siulá Grande; and the 10-day Huayhuash Full Trek, the complete circuit at a gentler pace with more time to acclimatize. Every package can be booked online with a deposit and paid in up to 3 installments — current prices and departure dates are on each tour page.

Both treks walk the same full Huayhuash Circuit loop — the difference is the line they take and the pace. The 8-day trek takes the alpine route over Trapecio Pass (5,000 m) and San Antonio Pass (5,020 m), with longer days of 6–8 hours and the closest views of Siulá Grande; it skips Laguna Viconga entirely. The 10-day trek follows the classic line through Portachuelo Pass and Laguna Viconga — where you soak in natural hot springs mid-trek — with shorter 5–6 hour days and gentler acclimatization. Choose 8 days if you're fit, acclimatized and short on time; choose 10 if it's your first high-altitude trek or you'd rather earn the same loop at a kinder pace. Either way, you cross the entire range.

The best time to trek the Huayhuash Circuit is May through September, the Andean dry season, when days are mostly sunny, trails are stable and mountain views are clearest. Expect warm days (15–20 °C / 59–68 °F) and cold nights that can drop to -10 °C (14 °F) at the highest camps. June to August is peak season with the most reliable weather — book early. April and October are quieter shoulder months with a higher chance of rain, and the November–March wet season is not recommended: passes can be snowed in and trails turn to mud.

Common symptoms of altitude sickness (AMS) are headache, nausea, loss of appetite, dizziness, unusual fatigue and poor sleep — usually appearing within the first days above 4,000 m. The most effective prevention is acclimatization: spend at least 2 days in Huaraz (3,050 m) before the trek doing easy day hikes, drink 3–4 liters of water daily, walk slowly the first days, eat light and avoid alcohol. On the trail, our guides serve coca tea each morning, monitor every trekker daily, and an emergency horse accompanies each group. If symptoms become severe, the only reliable treatment is descending — and our route always has an exit plan. If you have heart or lung conditions, consult your doctor before booking.

There is no government permit system for the Huayhuash Circuit. Instead, each of the 8 campesino communities along the route — Llámac, Pocpa, Queropalca, Quishuarcancha, Túpac Amaru, Uramaza, Huayllapa and Pacllón — charges its own entrance fee, totaling around S/. 280 (about US$75) per trekker for the full circuit, payable only in cash at checkpoints on the trail. On all Huayhuash Circuit packages these community fees are already included in your price: we pay them for you and keep the receipts, so you don't need to carry fee money or stop to negotiate. Bring your passport — communities register trekkers' details at some checkpoints.

In Huaraz, dozens of outdoor shops around Parque Ginebra and Avenida Luzuriaga rent quality gear by the day — down jackets, sleeping bags, mats and trekking poles — which is the cheapest option if you don't want to fly with bulky equipment. Buy (don't rent) anything that must fit your body well: broken-in hiking boots, base layers and socks, ideally at home before your trip. Lima also has international outdoor stores if you need something on arrival. Check your package details before renting a sleeping bag — several Huayhuash Circuit packages include one rated for -10 °C.

All water on the Huayhuash Circuit must be treated before drinking — every valley has grazing cattle and sheep, so no stream or lake is safe untreated. On our treks the cooks boil all water used for meals and hot drinks, and you can refill your bottles with boiled water at camp each morning and evening. For water you collect during the day's hike, the best systems are a squeeze or bottle filter (Sawyer Squeeze, Katadyn BeFree) for convenience, purification tablets as a lightweight backup, or a UV purifier if you prefer. Whatever you choose, carry a backup method — at 4,500 m, a cracked filter with no plan B is a real problem.

Every Huayhuash Circuit package page includes a free downloadable route map of that itinerary, marking camps, passes, altitudes, lakes and highlights — made by us specifically for the circuit you'll hike. For full topographic detail, the reference sheet is the Alpenvereinskarte 0/3c "Cordillera Huayhuash" (Austrian Alpine Club map), and apps like Gaia GPS or AllTrails offer offline topo layers — download everything before leaving Huaraz, as there is no cell coverage on the circuit. On guided treks navigation is our job, so maps are for your curiosity, not your survival.

Arrive in Huaraz (3,050 m) at least 2 full days before your trek and do one or two easy day hikes — it's the single most effective way to prevent altitude sickness on the circuit. We offer optional 1-day acclimatization hikes from Huaraz, bookable as an add-on to your trek and chosen to match your dates and fitness level. Sleep in Huaraz, hike high during the day, drink plenty of water and take it easy on alcohol. Not sure which warm-up hikes fit your itinerary?

There are currently no reliable commercial flights to Huaraz — service to its small Anta airport (ATA) is sporadic and seasonal at best. The practical route is to fly into Lima's Jorge Chávez International Airport (LIM), served from the US by LATAM, American, United, Delta, JetBlue and Avianca among others, then take a comfortable overnight bus to Huaraz (8–10 hours). Cruz del Sur, Oltursa and Móvil Tours run reliable "bus cama" services with fully reclining seats — book ahead for June–August. Leave at night, wake up in the mountains.
