In the south of São Miguel Island lies a long dormant volcano, with a crater six kilometers in diameter and slopes covered with dense forests. At the heart of this idyllic setting is Park Terra Nostra - the archipelago's oldest botanical park. With its origins dating back to the late 18th century, the park houses palm and bamboo groves, colossal gingkos and collections of plants unique in Europe and among the best in the world, such as the Cycadales and water lily collections. A fascinating natural space whose visit should include the unique experience of a bath in the thermal waters of the thermal tank, rich in essential minerals and with therapeutic properties.
