Laguna de Cuicocha is a crater lake at an elevation of 3.133m (10,278ft) above the sea level located in the Cordillera Occidental of the Ecuadorian Andes.
The road to the summit is asphalted. It’s called Vía Cotacachi - Quiroga – Cuicocha. It’s pretty steep, but in very good conditions. Lake Cuicocha is a caldera lake formed inside a collapsed volcanic crater with an island that looks like a guinea pig. Some 3km wide and 200m deep, the lagoon features two mounded islands that shot up in later eruptions. There are gas emissions from several locations in the caldera lake at present indicating the volcano is still active.
