No restaurants. No hotels. No beach vendors. No people. That's the appeal of Playa Sanctuario De Las Tortugas, a stretch of empty sand about a mile and a half south of La Barra De Potosí.
Getting there takes a bit of effort. Part of the year, a lagoon separates the village from the beach — you can rent a kayak to cross it. When the lagoon dries up, the trip can be made on foot or by horseback. Either way, it's a half-hour walk through an abandoned coconut plantation, passing iguanas, lizards, wildflowers, cacti, and the occasional coati.
The beach itself isn't great for swimming — powerful breakers crash right at the shoreline. But for walking, birdwatching, and solitude, it's hard to beat. Pelicans, kites, and other seabirds are constant company. Once in a while you might spot fishermen casting nets at the base of the cliffs to the west.
Bring water and a good book.
