Huayhuash Circuit Road — Chiquián to Llamac via the Cordillera Huayhuash High Passes
Glaciers, 15,700-ft passes, no guardrails.
The Cordillera Huayhuash sits in the Andes of central Peru and contains some of the most savage mountain terrain driveable by a vehicle anywhere on earth. The vehicle route linking Chiquián south to Llamac, then looping east through Cajatambo and up past Laguna Viconga toward Huayllapa, puts you on raw dirt tracks at altitudes that will humble any engine without a tune and any driver without experience. The pass at Cacananpunta tops out near 15,700 feet. You are looking at Siula Grande — the same peak Joe Simpson fell off in ‘Touching the Void’ — from the road. That context alone should calibrate your expectations.
This is an expert-level route requiring a properly acclimatized crew, a mechanically sorted high-clearance 4WD with low-range and a well-tuned engine for altitude, recovery gear, and enough fuel for 300-plus miles of remote driving since Chiquián is your last reliable fuel point. The tracks deteriorate significantly after rain — Andean wet season (November through April) makes sections impassable. Dry season, May through October, is your window. Permits are not formally required but local community checkpoints collect small tolls. Carry all water and food. Cell service is nonexistent. What you get is arguably the most spectacular mountain scenery in South America seen from behind a wheel.

Frequently asked questions
Can a stock Tacoma or 4Runner handle this circuit?
Only if it's a high-clearance, true low-range 4WD with a healthy engine — altitude at 15,700 ft will punish any vehicle running rich or poorly tuned. A stock Tacoma TRD Off-Road can manage mechanically, but naturally aspirated engines lose roughly 40–50% power at these elevations, so underpowered or modified rigs with emissions issues will struggle badly on the passes. Carry spare fuel filters, a basic tool kit, and know your rig's limitations before you go.
When is this route actually drivable?
May through October is your window — the dry season in the Peruvian Andes. Outside those months, the high passes turn to deep mud or snow and several sections become impassable even for capable 4WDs. June–August is the most reliable, though nights drop well below freezing year-round at elevation.
Do I need a permit to drive through the Cordillera Huayhuash?
Yes — you'll pay entry fees to the Comunidades Campesinas (local communities) at multiple checkpoints along the route; these are separate tolls, not a single park pass, and typically run $5–$15 USD per checkpoint. The southern fringe touches the Reserva Paisajística Nor Yauyos-Cochas managed by SERNANP (sernanp.gob.pe), which may require an additional entry fee. Carry Peruvian soles in small bills — card payments don't exist out here.
What's the hardest section and what actually makes it dangerous?
The high passes — particularly Cacanan Pass near 15,748 ft — combine loose shale, no guardrails, single-track width, and severe exposure on one or both sides. The danger isn't just the technical surface; it's that a wrong line or mechanical failure at altitude with no cell service means you're truly on your own. Approach every pass slowly, scout blind corners on foot, and never attempt them in deteriorating weather.
Where do you get fuel and water on this route — is there resupply?
Top off completely in Chiquián before leaving — it's the last reliable fuel stop, and the circuit has no gas stations. Water crossings exist throughout the route and mountain streams are generally clean at altitude, but carry a quality filter (Sawyer, MSR) and treat everything. Llamac has very limited supplies at the end; plan all food and fuel for the full 5–7 days from Chiquián.
