Santa Teresa Gallura is surrounded by wonderful beaches, such as La Marmorata, Porto Pozzo, Valle dell'Erica, and Porto Quadro.
Under the Longonsardo tower is Rena Bianca beach, which has been held the Blue Flag since 1987, in the inlet protected by Municca Island. "Porto Longonsardo" has held the same recognition since 2000.
 
Moving towards Capo Testa, you can admire the marvellous granites of Cala Spinosa, Costa del Faro and Cala Grande that take on fantastic shapes such as a dinosaur, a camel and an elephant.
In the narrow isthmus that joins Capo Testa promontory to Sardinia we find "Due mari" (Two seas) beach (ponente Ovest, Levante Est).
