The 2-year-old Hacienda offers a long list of family-friendly activities, including a save-the-turtles program, which gives visitors a chance to release baby turtles to the sea.
Within the last few months, guests have helped send more than 1,400 turtles on their way.
"We work closely with local officials on the turtle release program," said Ricardo Ramirez, Hacienda Beach Club & Residences general manager, who described the activity as a "one-of-a-kind experience" for guests.
Every year, female turtles, many of them Olive Ridley sea turtles -- also known as Golfina turtles -- lay thousands of eggs in nests on the beach. The eggs are protected from the time they're laid until they hatch in fall and winter, when the babies are aided in their struggle to reach the sea.
Besides the turtle-release program, the 22-acre, $250-million resort offers catamaran excursions, fitness courses and other activities.
Rates start at $550 a night, but a current special offers a 25% discount for guests who stay four nights and a 30% discount for those who stay five nights.
