Isla Mujeres Tortugranja

Although they are endangered, sea turtles are still killed throughout Latin America for their eggs and meat, which is considered a delicacy. Three species of sea turtle lay eggs in the sand along the island's calm western shore, and they are now being protected - one tortugita (little turtle) at a time.

In the 1980s, efforts by a local fisherman led to the founding of the Isla Mujeres Tortugranja, 5km south of town, which protects the turtles' breeding grounds and places wire cages around their eggs to protect against predators. Hatchlings live in three large pools for up to a year, then are tagged for monitoring and released. Because most turtles in the wild die within their first few months, the practice of guarding them through their first year greatly increases their chances of survival. Moreover, the turtles that leave this protected beach return each year, which means their offspring receive the same protection.

There are several hundred sea turtles, ranging in weight from 150g to more than 300kg. The farm also has a small but good-quality aquarium, displays on marine life and a gift shop. Tours are conducted in Spanish and English.

If you're driving, cycling or walking from the bus stop, bear right at the 'Y' just beyond Hacienda Mundaca's parking lot (the turn is marked by a tiny sign). The facility is easily reached from town by taxi.
