Some 10% of Mexico's total area is protected and there are 67 national parks. Here you can find tundra, high sierra, rainforest, and coral reefs. You can experience desert stargazing amid centuries-old cacti; silent canoe trips through near-impenetrable mangroves; heart-stopping races down river rapids; hiking through thick forests and mountain scenery. Wildlife varies from delicate monarch butterflies, to javelinas (skunk pigs), to monkeys and jungle cats. Ranging in size from the 20 acre El Sabinal National Park, lining a wet arroyo near Cerralvo in Nuevo Leon, to the 1,289-square-mile Arrecife Alacranes off the shore of Progreso, Yucatán, Mexico offers hugely varied adventures. And don't miss the Basaseachi Waterfalls National Park, famous for its thick pine and oak forests, spectacular rock formations, amazing views, and the country’s two highest waterfalls: Piedra Volada and Basaseachi.
