The Arenal Volcano sits in northwestern Costa Rica, where a number of hot springs can be found. The temperature of most resort and spa pools ranges from 90 degrees F to 105 degrees. Smaller spas like the Eco Termales Hot Spring provide a quiet and relaxing experience, while the Baldi Hot Spring, with 30-plus pools and a number of other amenities and attractions (think swim-up bars and water-slides), is an affordable and accessible option for those seeking a more-resort-like destination. Many area hotels also have pools of hot spring water. Some of these are set up so that guests can view the volcano while they soak. Arenal might seem a bit touristy to some, but the springs are some of the most accessible in the Americas, and the location brings a level of exotic excitement that other geothermal destinations cannot match.
