A windsurfing and sailboarding haven thanks to its constant winds, the lake offers numerous recreational activities.

  • Absolutely beautiful area with magnificent views.
  • Beauty of the lake is in its dramatic settings. Lush jungle and the Arenal volcano are mirrored in the lake. There is a lot of wildlife in jungle around the lake, including snakes.
