S'Enclusa - also known as S'Arenalet - forms part of the Sivinar de Mongofre Nou that reaches up to the gravel and sandy beach. This hard-to-reach beach is 120 metres long and 25 metres wide.
It was planned to establish an information centre about the biosphere reserve on this hill which had been used by the US-army until the nineties and had since then been abandoned.
This peak, the "Puig de S'Enclusa", in the municipality of Ferrerias, is 174 metres high and thus the second-highest elevation on Menorca after Monte Toro.
The project is frozen for the time being due to the lack of 7 million Euro required for the centre.
