A smallish horseshoe curve of fine white sand, framed by almost vertical pine-covered cliffs, is where Menorca's only river, the Agendar, reaches the sea through a long limestone gorge. The surrounding area is under environmental protection—the handful of resort hotels and chalets above the beach (usually booked solid June to September by package tour operators) were grandfathered in. Cala Galdana is family-friendly in the extreme, with calm shallow waters, and a nearby waterpark/playground for the kids. A favorite with Menorcans and visitors alike, it gets really crowded in high season, but a 20-minute walk through the pine forest leads to the otherwise inaccessible little coves of Macarella and Macaretta, remote beaches popular with naturists and boating parties. Amenities: food and drink, lifeguards, showers, water sports. Best for: swimming, walking.
