Cala Sa Nau is a hidden gem on Mallorca's southeast coast, tucked away in a mini fjord-like bay with crystal-clear waters and white sandy beaches. Perfect for a day trip, this idyllic cove offers great swimming and snorkeling opportunities, with rocky cliffs on either side of the bay adding to its charm. While it may be a bit tricky to get to, the lack of crowds and unspoiled beauty make it well worth the effort. Plus, there's a beach bar serving up refreshing drinks and snacks, making it a relaxing spot to soak up the sun and enjoy the peaceful surroundings.
