The Monchique Islet is a small islet, west of the village of Fajã Grande, off the coast of the island of Flores, in the western part of the Portuguese archipelago of the Azores. It is the westernmost point of Portugal and if considered part of Europe is its westernmost point as well.
Approachable only by boat, the bay, which has water depth of about 43 metres, provides opportunities for scuba diving during the day in the summer. The islet and the waters around it are protected for its rich biodiversity; ninety-six species of flora and fauna have been identified congregating on or in the waters of the islet, including the species of brown algae, limpets, barnacles and Mediterranean rainbow wrasse.
