Not quite 3 km (2 miles) north of Punta Chiqueros, a long stretch of beach begins along the Chen Río Reef. Turtles come to lay their eggs on the section known as Playa de San Martín. Soldiers or ecologists sometimes guard the beach during full moons from May to September to prevent poaching. This is a particularly good spot for swimming when the water is calm (and the turtles aren't nesting). When the wind is blowing from the south though, the water is best for kiteboarders and windsurfers. When you're ready to kick back, La Palapa de St. Martin serves cold drinks and seafood. Amenities: food and drink; lifeguards (part-time); parking (free). Best for: swimming; solitude.
