Lake Arenal

Lake Arenal extends across 85 square kilometers with depths ranging from 30 to 60 meters, making it the largest lake in Costa Rica.

The construction of the Sangregado Dam in 1979 expanded Lake Arenal to triple its size, submerging two towns that required relocation to new areas.

Local fishermen maintain traditional practices by catching rainbow bass and machaca fish species, which thrive in the lake's clear waters.

From November through April, strong winds create favorable conditions for windsurfing and kitesurfing activities across the northern section of the lake.

The lake generates hydroelectric power that supplies 17 percent of Costa Rica's electricity needs while supporting over 300 bird species in its ecosystem.
