XcaretThe massive nature park called Xcaret may be the Riviera Maya’s most touristy attraction, but there’s a reason it’s popular: It’s the only place in the area where you can do it all—snorkel, visit animal habitats, swim through an underground river, try different Mexican delicacies, play with dolphins, learn about Mayan culture, and take in traditional regional dances at an extravagant nightly show—all in a single day. What’s more, it’s remarkably baby- and toddler-friendly. The so-called Plus pass is a smart option that includes lunch, lockers, and snorkel gear for a price equal to general admission and a meal. Best day of the week to visit: Tuesdays, for smaller crowds. Best season: early November, for Day of the Dead.
