Dr. Alfredo Barrera Marín Botanical Garden is just a 10-minute taxi ride from Puerto Morelos. It's a fun and fascinating place to spend an afternoon when you're not swimming in the sea and cenotes.

Opening in 1982, this botanical garden is one of the largest in Mexico. It encompasses the last patch of preserved forest between Cancun and Playa del Carmen.

Naturally, the mission of this botanical garden is to conserve local and regional flora. There are over 300 species of cacti, palm trees, and more growing on this lush 160-acre woodland. There's also a walking trail to a ruined ancient Mayan site.

It's open 8:00 AM-4:00 PM from Monday to Friday. The entrance fee for foreign visitors is around 500 pesos.
