Lago Arenal

Near the volcano of the same name, in 1979 Lago Arenal was enlarged to be three times its original size. This was done by I.C.E (Instituto Costarricense de Electricidad) to create a hydroelectric dam that would provide energy to the whole country. Now, it produces 12% of the entire country’s energy. The lake is also a popular place to fish, boat, and windsurf.
