Cala Cumpultittu is a small, secluded beach on the western coast of Sardinia, in the district of Bosa.
The shoreline has a fine grey sand, surrounded by volcanic rocks, smoothed by the sea on both sides.
The seabed slopes down slightly and the beach is basically protected against all the dominant winds in the area.
Typical rocks in this area include ignimbrite (also known as tuff), linked to the ancient eruptions of volcanic ash (around 16 million years ago).
The action of the sea formed the tuff creating unusual shapes and small caves.
The beach is easy to reach down a steep but manageable path which starts from the panoramic parking area.
Like all the beaches in this area of the island, Cala Cumpultittu is also part of the Sites of Community Importance (SCI) “Hinterland and coastal area between Bosa, Capo Marargiu and Porto Tangone” (ITB020041), regulated by the Rete Natura 2000.
