Seclusion factor: You take a ferry or boat to reach the island―look for porpoises on the way. Be ready for a rustic atmosphere. Streets are sand, so no one is in a hurry. Sign up for the biggest attraction: tours to see pods of whale sharks, which thrive offshore.
What makes it special: Here, you’ll find no nightclubs or crowds. Above all else, Holbox is a fishing village. You can’t find fresher snapper, lobster, or ceviche. For dessert, wander into Helados Maresa, a private home that doubles as an ice-cream parlor.
