Surrounded by volcanic landscapes, this open-air geothermal pool invites you to soak in its warm, milky-blue waters. Rich in natural minerals, the lagoon is especially known for its skin-soothing effects. You can try a signature white silica mask, unwind in the steam or sauna, or simply float and take in the otherworldly scenery. Spa treatments are also available for those who want an extra dose of relaxation. This tour will be an additional $189 per person. Children aged 2- 13 accompanied by an adult - free.
