Located very close to the Lagoa do Fogo, you can pay to enter and just walk around the park, or you can pay more and take a dip. There are three pools of thermal waters with temperatures between 34 and 38 degrees Celsius. After the pools, I recommend to swim in the waterfall, it's colder (maybe 25 degrees Celsius), but it is perfect to finish there with a swim. #swim #thermalsprings #waterfall #pool #caldeiravelha #azores #portugal
