Jardín Botánico Dr Alfredo Barrera Marín Puerto Morelos

One of the largest botanical gardens in Mexico, this 65-hectare reserve has about 2km of trails and sections dedicated to epiphytes (orchids and bromeliads), palms, ferns, succulents (cacti and their relatives) and plants used in traditional Maya medicine. The garden also holds a large animal population, including the only coastal troops of spider monkeys left in the region. It's 1.3km south of the Puerto Morelos turnoff. Bring mosquito repellent (June to November) and water.
