Cuicocha, Crater lake in Imbabura Province, Ecuador
Cuicocha is a crater lake in Imbabura Province formed inside a volcanic caldera. Two islands of volcanic rock emerge from the water, which reaches depths of around 200 meters in its deepest areas.
The lake formed roughly 3000 years ago through volcanic activity that created a large caldera. Over time, natural springs filled this basin with water, creating the body of water we see today.
The name comes from the Kichwa language meaning 'guinea pig lake', a reference to indigenous peoples who raised guinea pigs in this region. This link to local heritage shapes how people think about the place today.
The lake is best explored by boat, with regular tours departing from the main dock. Visitors should wear sturdy shoes and bring a jacket, as it can be cool at this higher elevation.
The water stays at a constant temperature of around 15 degrees Celsius year-round thanks to geothermal heat below the surface. This steady warmth creates an unusual environment found in few other lakes in the region.
