Cala Rossa, Favignana

Cala Rossa transforms an old tuff quarry into a natural infinity pool with impossibly blue water that registers a pH of 8.2 and visibility exceeding 20 meters. Despite its popularity, the beach remains uncrowded on weekdays, with numbers staying under 200 visitors per day. The tuff walls provide natural shade from 3 p.m. onward, reducing the need for umbrellas by half.
