The genesis of the Azores is found upon 1766 volcanoes, nine of which are still dormant. Underground, almost three hundred volcanic cavities, including caves, ravines and cracks, have been surveyed. The landscape is filled with dry calderas, craters lakes, fumaroles and thermal water springs. In the sea, there are submarine geothermal springs. The mountain of Pico, majestic and with an intact cone, appears to be protecting all this geological wealth. The volcanism of the archipelago impresses for its diversity and creates its own magnetism. It is a witness to the power of Nature, and the basis for very special experiences.
