Costa Rica's Caribbean coast is a world apart from the rest of the country. The pace is slower, the food is spicier, the tropical heat is more palpable, and the rhythmic lilt of patois and reggae music fills the air. This remains one of Costa Rica's least discovered and explored regions. More than half of the coastline here is still inaccessible except by boat or small plane. This isolation has helped preserve large tracts of virgin lowland rainforest, which are now set aside as Tortuguero National Park ★★ and Barra del Colorado National Wildlife Refuge ★. These two parks, on the coast's northern reaches, are among Costa Rica's most popular destinations for adventurers and ecotravelers. Of particular interest are the sea turtles that nest here. Farther south, Cahuita National Park ★★ is another popular national park, located just off its namesake beach village. It was set up to preserve 200 hectares (494 acres) of coral reef, but its palm tree-lined white-sand beaches and gentle trails are stunning. When you’re ready for nice lodging, fine dining, and a hearty party, the village of Puerto Viejo ★★ is hard to top anywhere in Costa Rica.
