Lake Arenal, a shimmering expanse of blue water stretching west of the active Arenal Volcano, is Costa Rica’s largest lake and a striking feature of the landscape. This human-made reservoir not only offers picturesque views but also serves a vital role as a hydroelectric dam, generating sustainable power for the region. Visitors can take in the serene waters and the dramatic backdrop of the volcano, making it a popular spot for both its natural beauty and functional significance.
