Jardín Botánico Dr. Alfredo Barrera Marín
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.
