A few kilometers west of Puerto Escondido, the Palmarito sea-turtle camp collects tens of thousands of new-laid turtle eggs each year, and reburies them in a fenced enclosure to protect them from human and animal predators. When the baby turtles hatch after about six weeks, visitors can help release them into the sea (donations welcome).

Lalo Ecotours and other agencies take groups from town to participate for around M$300 per person: look for 'Liberación de Tortugas' signs. The camp is down a track off Hwy 200 just after the Km 134 marker, 3km past the airport.
