Huayhuash Circuit Road — Llamac to Cuartelwain via the Cordillera Huayhuash High Passes
6,000m glaciers. Zero guardrails. Real Peru.
The Huayhuash Circuit is one of the most spectacular high-altitude loops on earth, and the vehicle-accessible sections between Llamac and Cuartelwain via Mitucocha and Carnicero base are no joke. You’re threading dirt tracks cut into Andean hillsides with Yerupajá (6,635m) staring you down the whole time. The road deteriorates past Pocpa into rocky single-track that threads alongside ichu grassland and freezing quebradas. Key waypoints: Llamac village (3,250m), the rough climb toward Pampa Llama, and the final push to Cuartelwain at the circuit’s eastern edge. River crossings are seasonal — the Río Llamac and its tributaries run hard in the wet season and can swallow axles.
This is Expert-level terrain. You need a capable high-clearance 4WD — a Hilux or Land Cruiser 70-series in good condition is the minimum. Don’t even think about it with street tyres. Best season is June through September; outside that window the tracks turn to axle-deep mud and passes can close with snow. Fuel in Chiquián before departure — nothing reliable beyond that. Carry 20+ litres reserve, 3–4 days of food, and a satellite communicator. No cell service once past Llamac. Permits via local arriero agreements. What you get: genuine solitude inside one of the world’s most dramatic mountain circuits, with glaciated 6,000m peaks as your constant company.

Frequently asked questions
What's the minimum vehicle setup to actually complete this circuit?
High-clearance 4WD is non-negotiable — think at minimum a Hilux or Land Cruiser with a locking diff, all-terrain tires, and a full recovery kit including traction boards and a hi-lift jack. Stock SUVs with road tires will not make it through the rocky high passes and river crossings. Bring a spare fuel jerry can; the nearest reliable fuel is back in Chiquián.
When is this route actually passable and what kills access in the off-season?
June through September is the dry season window — the only realistic time to attempt this. Outside that window, the high passes turn to deep mud or ice, river crossings swell dangerously, and snow can close sections above 4,500m entirely. Don't push it into October.
Do you need a permit to drive the Huayhuash Circuit and how do you get one?
Yes — the route passes through the Reserva Paisajística Nor Yauyos-Cochas managed by SERNANP Peru, and community-managed checkpoints along the circuit charge local access fees (typically paid in cash at the gate, per person and per vehicle). Check current requirements directly with SERNANP at sernanp.gob.pe before you leave, as fees and rules change. Bring soles in small bills.
What's the hardest section of the route and what are you actually dealing with?
The passes above 4,800m — particularly the approach to Punta Cuyoc near the southern section — are the crux. You're navigating loose rock and embedded boulders on shelf roads barely wider than your rig, with no guardrails, steep drop exposure, and potential for sudden afternoon weather. Altitude compounds everything: your engine loses significant power and your reaction time degrades if you're not acclimatized.
Is there any cell service on the route and how do you handle emergencies out there?
There is zero cell service for the entire 100km circuit — plan as if you're completely off-grid for up to 6 days. A satellite communicator (Garmin inReach or SPOT) is not optional at this remoteness level; the nearest medical help is in Chiquián or Huaraz, hours away on rough roads. Travel with at least one other vehicle.
