Now through the end of the year, guests of the four-diamond CasaMagna Marriott Puerto Vallarta Resort & Spa can experience a spectacle of nature as well as a special offer from the luxury beach resort.

Along with its Sand Dollar Package, the Puerto Vallarta hotel is proud to continue its Sea Turtle Protection Program. Since beginning 11 years ago, the hatching initiative has safely delivered more than 337,000 baby turtles to the sea. In 2012 alone, the hotel recovered 784 nests and released 44,631 turtles back into the wild.

The beach protection area at the Puerto Vallarta resort is more than a half-mile long and houses 30 percent of the area’s nests. From June through December, the resort coordinates with renowned biologist Catherine Hart and her team as well as government officials to help conserve the Olive Ridley sea turtle.

Every night during the summer through fall, dozens of turtles arrive at the hotel’s beaches. From 11 p.m. to 5 a.m., biologists protect the sea turtles and collect their eggs so beach-goers can’t accidentally disturb the nests during the day. The eggs are taken to a nursery at the resort where, after about 45 days, baby turtles are born. Biologists and hotel staff allow resort guests to see the turtles and learn more about them. Children are invited to name the turtles, wish them luck and then set them free. The turtles are returned to the sea at the edge of the resort’s beach, where some of them will return a decade later to start the process again.

The best way to enjoy the sun and surf at the resort is by taking advantage of the Sand Dollar Package. The package includes a deluxe room starting at $119 per night, $50 USD daily resort credit and every fourth night free.

The Puerto Vallarta resort offers luxurious surroundings, exceptional guest rooms and fine dining. All rooms feature wonderful views from private balconies, Marriott’s popular Revive bedding for a restful night’s sleep and available high-speed Wi-Fi Internet access.

For dining, the resort features La Estancia’s old world Mexican charm combined with contemporary style. Mikado has Thai and Japanese and sushi. The pool and beachside Las Casitas makes fresh seafood and salad dishes as well as grill specialties. Champions Sports Bar is perfect for catching a big game in a casual atmosphere.

The CasaMagna resort also features a high-tech fitness center and the luxurious full-service of Ohtli Spa. The fitness center has updated equipment and offers Pilates, yoga and spinning classes. Guests can enjoy the quiet splendor of Ohtli Spa, which features body scrubs and wraps, facials and therapy baths. Couples also can enjoy a massage together at the luxurious Iyari Suite. The resort also has several other water options, including an indoor pool, infinity pool and outdoor kid’s pool.

Besides the Sea Turtle Protection program, visitors can also enjoy the nature at the Vallarta Botanical Gardens or visit the hidden beach at Marietas Island.

More adventure can be found in downtown’s shopping and nightlife districts.
