Just as the Siete Lagos area is known for its abundance of hot springs, the Puyehue area also has its share of healing waters. While many of the hot springs lie in remote areas, visitors have two easily accessible options, the first being the thermal springs of one of Chile’s most famous and fashionable hotels, the Hotel Termas de Puyehue. Here both the indoor pools and outdoor pools are open to non-guests; a day pass gives access to the pools, saunas and restaurants.
The second, and cheaper, option is the resort at Aguas Calientes, right at the entrance to the Parque Nacional Puyehue. It has tinas (personal bathtubs), double tinas (so you can bathe with a friend), a hot outdoor pool and a very hot indoor pool; use of the latter is included in the price of a cabaña in summer.
