Laguna de Apoyo is a beautiful volcanic lake near the town of Masaya.
The Laguna waters are mineral rich and clean and safe to swim in.
The reserve that the Laguna is in is host to monkeys, iguanas, falcons, vultures, possums, common boas and more.
Most tours from Granada take visitors to the vista of the lake from the town of Catarina and charge separately for a visit to the lake to swim.
However, you can do a tour which includes the volcano, artisans market and a swim at Laguna de Apoyo.
