Interestingly, Lake Caliraya in Laguna is a man-made lake situated in three towns—Lumban, Cavinti, and Kalayaan. It is now an ecological destination where one can enjoy nature’s unspoiled beauty. The man-made lake covers partly submerged land areas and this resulted to numerous islands complete with coves. These islands are now built with vacation houses private villas, and resorts. The cool mountain breeze of Sierra Madre and the deep waters of the lake combine to make Caliraya an excellent place for various water activities such as boating, jetskiing, waterskiing, and windsurfing.
