Discover more about Lake Arenal

Lake Arenal, cradled in the northern highlands of Costa Rica, is more than just a picturesque body of water; it's a testament to the country's commitment to sustainable energy and ecotourism. This 85-square-kilometer lake, the largest in Costa Rica, was created by the construction of the Presa Sangregado Dam between 1972 and 1976, tripling its original size. The project, while providing essential hydroelectric power, also led to the relocation of the towns of Arenal and Tronadora, now submerged beneath the lake's surface. Today, Lake Arenal is a hub of activity, offering a diverse range of experiences against the backdrop of the majestic Arenal Volcano. Its consistent winds make it a world-renowned destination for windsurfing and kitesurfing, while the calm waters invite kayaking, paddleboarding, and boat tours. Fishing enthusiasts can try their luck at catching rainbow bass and machaca, two popular species in the lake. The hillsides surrounding Lake Arenal are teeming with wildlife, making it a paradise for nature lovers. Over 120 species of mammals, 300 species of birds, and 2,000 species of plants thrive in the area. Keep an eye out for howler monkeys, white-faced capuchin monkeys, giant iguanas, and a variety of bird species. Lucky visitors might even spot a tapir or a jaguar. Beyond the lake itself, the surrounding area offers a wealth of attractions. Explore the Arenal Volcano National Park, hike through lush rainforests, or relax in natural hot springs. Visit the town of Nuevo Arenal, built to replace the original Arenal, and experience the local culture. With its stunning scenery, diverse activities, and commitment to sustainability, Lake Arenal is a must-see destination for any traveler to Costa Rica.
