Visiting Lake Arenal

Lake Arenal sits beneath the majestic Arenal Volcano in the northern part of Costa Rica. It is 85 square kilometers, man-made and is 30 to 60 meters deep, depending on the season. It is the biggest lake in Costa Rica provides essential hydroelectric power generation for the country. There are two fish species that live in the lake, the machaca and the famous rainbow bass, making it a popular fishing destination. Over 100 other mammals survive thanks to the lake’s water supply. Go hiking around the lake and you’ll spot hundreds of bird species, tapirs and maybe even a jaguar (unlikely, but jaguars do live off of the lake). Paddleboarding, windsurfing and kayaking are very popular among tourists and locals. Between November and April you’ll see a higher number of windsurfers and kitesurfers thanks to the strong, consistent winds that blow over the beautiful lake.

Earthen Dam and Disappearing Islands

Once the hydroelectric dam was finished in 1979, Lake Arenal was 3 times bigger than it was originally. There are two abandoned cities at the bottom of the lake that were moved to east side during construction of the dam. The deepest part of the lake is 180 feet deep. However, the depth adjusts throughout the year, and when the lake is shallower, you can see some islands appear.

The massive Arenal Volcano and lush rolling hills in the background, along with the shining blue waters, make Lake Arenal an incredible area for water and adventure activities, hiking, horseback riding, wildlife spotting and photography. The surrounding hotels, spas, hot springs and tourist towns make Lake Arenal and the Arenal Volcano one of the most popular tourist destinations in Costa Rica. Don’t skip this area on your next Costa Rica vacation!
