Situated in the heart of the Furnas Valley – a dormant volcanic crater – on the Azores island of Sao Miguel, Furnas is something of a geothermal marvel. Visitors can relax in steaming thermal baths in Terra Nostra Park, learn about and sample the therapeutic spring waters, or simply walk around the beautiful crater lake. Meanwhile, foodies can enjoy Portuguese stew 'cozido', cooked in pots placed in holes in the hot volcanic soil, as well as freshly-made tea, created with the help of hot spring water.
