Apoyo Lagoon is a volcanic lake formed more than 20,000 years ago in the crater of an extinct volcano. The lake and the area around the lake have been a protected area since 1991. The shore of the lake has been adapted to visitors in the form of a series of hotels offering tourists accommodation, but also programs such as diving, paragliding, various water sports, and hiking. The lake is rich in fish, and in the vicinity of the lake, it is possible to see several species of monkeys, iguanas, boas, wild cats, opossums, and many other animal species. The tropical forest is rich in various types of plants, so visitors are happy to return to the Apoyo Lagoon to enjoy swimming and nature.
