Reserva Natural Laguna de Apoyo, Protected volcanic lake area in Masaya and Granada, Nicaragua
The Reserva Natural Laguna de Apoyo is a circular crater lake that forms the largest volcanic lake in Nicaragua, reaching depths of 176 meters. The basin spans roughly 6 kilometers across and sits between the departments of Masaya and Granada, framed by steep green slopes.
The water body formed roughly 23,000 years ago following the eruption of the Pre-Apoyo Volcano, which created the current crater structure. The eruption left behind a stable basin that filled with water and became one of the region's most distinctive geographic features.
The lake served as a center for fishing and spiritual practices among indigenous communities, who left petroglyphs along its shores as records of their beliefs. These ancient marks still stand as evidence of the deep connection between people and this water.
Visitors can swim, scuba dive, and kayak here, with access via an unpaved road from kilometer 37 of the Masaya-Granada highway. It is wise to bring sturdy shoes since paths to the water can be uneven, and the easiest access occurs during drier months.
Volcanic gases still escape at certain spots in the lake and create natural hot springs, particularly when water levels reach their peak. This underground activity reminds visitors that the water sits within an active volcanic system.
