The Laguna Cuicocha hike follows the rim of a 3 km wide volcanic crater in Imbabura province, northern Ecuador, for about 14 km. It takes 3.5 to 5 hours, needs no guide, and entry is free. The lake sits a little above 3,000 m and the rim rises to about 3,246 m, which makes it one of the best acclimatization days in the country before Cotopaxi or Chimborazo.

The loop
The path starts and ends at the lake entrance and runs all the way around the crater rim. The name Cuicocha is usually translated as guinea pig lake, after the shape of the largest island in it. The path climbs and drops along the rim rather than staying level, and the highest stretches are where the wind hits hardest.
If you want a shorter outing, walk part of the rim and come back the same way, or take one of the boat rides that run on the lake.
Why hike Cuicocha before the volcanoes
Good acclimatization means walking high and sleeping lower, a little more each day. Cuicocha does that: you spend 4 or 5 hours around 3,100 to 3,250 m and sleep in Otavalo or Cotacachi, lower down. In Cusco we hold our Inca Trail groups to at least two nights at altitude before the Classic Inca Trail crosses 4,215 m, and the same thinking applies here: Cuicocha is a sensible second or third day in Ecuador, before you sleep at a 4,850 m refuge. Our altitude sickness guide covers the symptoms.
Best time and weather
You can walk the rim all year. Mornings are usually clearer, and cloud and showers are common in the afternoon, so start early. The sun at this altitude on the equator burns fast even when it feels cool; wear a hat and sunscreen, and bring a windproof layer for the exposed sections.
Getting there
Most hikers take a taxi from Cotacachi or Otavalo to the lake entrance and arrange the return trip with the driver. Otavalo is reached by bus from Quito. For Cotopaxi, Chimborazo and the Quilotoa Loop, see our page on Ecuador hiking trails; for the rest of the trip, our Ecuador travel guide.
What to bring
- Walking shoes with grip; the rim path is slippery when wet
- Windproof and waterproof jacket, warm layer
- Hat, sunglasses and SPF 50+
- 1.5 to 2 litres of water and lunch
- Cash for the taxi
