Most of the 125 beaches on Menorca’s jagged coastline have little, if any, development. Along the south coast, paths that start at inland parking lots wind through forested ravines to beaches. Cala Mitjana’s white sand is surrounded by cliffs. The shallow water makes it easy to explore a cave and the rocky crags with snorkeling gear. In the north, Cala Cavalleria is easier to get to. The water may feel warm into autumn, and visiting after the peak summer months means paying half-price for activities like hiring a boat with private captain.
