The Montaña Amarilla is a protected Natural Monument whose marine part is located within the ZEC “Sebadales del Sur de Tenerife”. The predominant landscape is typical of the southern coast, with two main terrestrial ecosystems: the cardonal-tabaibale belt and the coastal halophytic belt. Its geology is spectacular and the presence of a fossil dune at the foot of the caldera stands out. It is a little gem that has been freed from tourist construction. It is bordered to the south by a small bay well protected from the prevailing trade winds. It’s a great place for hiking, birdwatching, and various water activities like bathing, swimming, snorkeling, or diving.  The submerged part is also spectacular: large rocky outcrops of volcanic origin stand out vertically above the sandy bottom, such as those called La Puerta, La Aguja or La Piedra Narayán. The fossil dune at the foot of the caldera continues underwater, with spectacular formations. We can appreciate almost all the shallow underwater ecosystems of Tenerife: algae and blanquizales on rocks, sandy bottoms (including eels and sebadals) and a large number of holes and crevices. In recent years there has been a regeneration of life and species of interest to diving.
