A deep, clear crater lake inside a forested caldera between Masaya and Granada, and the easiest place near Managua for a swim.
What it is
Laguna de Apoyo fills a large volcanic caldera between the cities of Masaya and Granada. The lake is deep, clear and warm, and the steep slopes around it are covered in tropical dry forest, protected as a nature reserve. From the rim, especially from the lookout at Catarina, the view down into the bowl of blue water is one of the most photographed in Nicaragua.
What to do
Most visitors come to swim, which is the big difference from Lake Managua. The water is calm, and small lodges and day-use places along the shore offer access to docks, kayaks and paddleboards. Birdwatching is good in the forest on the slopes, and howler monkeys are often heard in the trees. Many people simply spend a day reading in a hammock and swimming when it gets too hot. In the evening the crater rim blocks the city lights, and the sky over the water can be full of stars.
A little background
The caldera formed in a major volcanic eruption many thousands of years ago, and the lake slowly filled it with water. Its clear water and its isolated position have made it of interest to scientists studying freshwater fish. The reserve status helps protect the forest on the crater walls, so stick to paths and leave no trace.
Getting there and staying
The road down into the crater is steep and winding; taxis and drivers from Managua, Masaya and Granada make the trip, and some lodges arrange transfers. The lagoon works as a day trip from Managua or as an overnight stay. Arrangements for day visitors, such as entry to shoreline facilities, vary from place to place, so ask in advance. Bring sun protection, water shoes, insect repellent and cash in small notes. Combine the lagoon with the Masaya circuit or Granada.
