Speleology

Several islands turn out to be irresistible for the unusual formations and the flora that volcanoes originated, as,like in Terceira to the Algar do Carvão. It is gooo to have a guide to the Caves of the Balcões, Agulhas and Natal, as well as to the Algar do Montoso if São Jorge is visited or to the Furna of the isla of Pico.
