Lake Arenal, La Fortuna de San Carlos

Costa Rica's largest lake, Lake Arenal encompasses about 85 sq km (32 sq mi). Originally much smaller, the lake tripled in size when a huge dam was built in the 1970s. Get on the water to admire the surrounding natural scenery, green undulating hills surrounding the deep blue lake, and the Arenal Volcano in the background. A windsurfing and sailboarding haven thanks to its constant winds, the lake offers numerous recreational activities. Take a boat tour and enjoy the picturesque landscape, go fishing for rainbow bass, rent a kayak, or explore the surroundings on bike, foot, or horseback.
