The stretch near the water’s edge has a pebbly seabed. A few metres further out, the pebbles make way for the sand and the colour of the water suddenly becomes turquoise, giving you the feeling of a natural pool surrounded by greenery. Cala Regina is a bay surrounded by cliffs covered with eucalyptus and pine trees, located along the coast of Quartu sant’Elena, alongside which the scenic provincial road SP 17 runs. The beach consists mainly of rocks and pebbles, with some areas of amber-coloured sand. The transparent, turquoise water alternates with emerald green reflections and the seabed is ideal for snorkelling, underwater fishing and diving, especially near the granite rocks at the foot of the western promontory. Here, you will spot shoals of seabream and damselfish, as well as numerous octopuses and cuttlefish.
