Top Reasons to Go

Soak in a volcano-heated hot spring: For four decades Arenal was one of the world's most active volcanoes, but it has been in a state of slumber since 2010. It still provides a majestic backdrop for the steamy thermal waters nearby.

Hike to a waterfall: The reward for a tough hike down to La Fortuna Waterfall is a magnificent waterfall, plummeting nearly 250 feet into a freshwater pool.

Float on a cloud: Explore Monteverde's misty world on treetop walkways or on exhilarating ziplines up to 328 feet off the ground.

Watch wildlife: Birds, monkeys, turtles, caiman, and sloths abound in the 25,000-acre Caño Negro National Wildlife Refuge.

Set sail: Lake Arenal is one of the top windsurfing and kitesurfing spots in the world; winds can reach 50 to 60 mph mid-November through April.
