3 Best Sights in Puerto Morelos, The Riviera Maya

The biologists running the Croco Cun Zoo, an animal farm just north of Puerto Morelos, have collected specimens of many of the reptiles and some of the mammals indigenous to the area. They offer immensely informative tours—you may even get to handle a baby crocodile or feed a monkey. Be sure to wave hello to the 500-pound crocodile secure in his deep pit.

This 150-acre botanical garden is the largest in Mexico. Named for a local botanist, it exhibits the peninsula's plants and flowers, which are labeled in English, Spanish, and Latin. The park features a 130-foot suspension bridge, three observation towers, and a library equipped with reading hammocks. There's also a tree nursery, a remarkable orchid and epiphyte garden, an authentic Maya house, and an archaeological site. A nature walk goes directly through the mangroves for some great birding; more than 220 species have been identified here (be sure to bring bug spray, though). Spider monkeys can usually be spotted in the afternoons, and a tree-house lookout offers a spectacular view—but the climb isn't for those afraid of heights.

Newcomers to Puerto Morelos might be disappointed by the blankets of seaweed and boats that dock ashore—after all, this place is more about snorkeling on the reef than sunning on the sand. Your best bet is to head for the stretch of beach two blocks north of the square in front of Ojo de Agua Hotel. Park on the town square or adjacent streets. Amenities: food and drink; parking (no fee). Best for: snorkeling; walking.
