With its soaring volcanos, tropical rainforests, and white-sand beaches, Costa Rica is a veritable paradise for outdoor adventure. And with the right guide, nothing is too extreme. Although many Costa Rica tours will give you an adrenaline rush, like ziplining or whitewater rafting, there’s also no better place to take a rest day. Set sail from the Caribbean or Pacific coast, sample farm-fresh cacao and coffee, or explore the museums and markets of San Jose.
