Mexico is one of the planet's most underrated wildlife destinations: it sits at the meeting of two oceans, hosts the entire monarch butterfly migration, has the world's second-largest reef, plus jaguars, whale sharks, gray whales and three species of sea turtle. The catch — most of these are seasonal. This guide gives you three 10-day variants depending on when you can travel.
Why Mexico for Wildlife
Few countries pack this much biodiversity into a single trip. The Mesoamerican Reef along the Caribbean coast, the cold Humboldt-influenced Pacific, the central highlands' fir forests, and the Yucatán's underground rivers create radically different ecosystems within a 2-hour flight of each other.
