Arriving at the end of the line, the exhilarating adventure of whizzing down the mountain begins. Connect to a zip line cable stretching over rainforest treetops and clifftops. After traversing seven cables and reaching heights of 660 feet (201 meters), you'll arrive back at the starting point of the adrenaline-pumping adventure.

Explore the thrilling Arenal Hanging Bridges on this popular excursion. The trail system, located inside a rainforest reserve, features suspension bridges that take you high above the treetops before treating you to a once-in-a-lifetime view of Arenal Volcano.

Go waterfall rappelling, also known as canyoning, in the jungle. This activity is one of the most popular adventure sports in Costa Rica. In a canyon in the heart of the rainforest, your guide will provide brief safety instructions and outfit you with a harness. You'll then rappel down the side of three different waterfalls, feeling the mist and spray of the falls as you descend along a wall of rocky cliffs. Finish with a splash into the largest waterfall's pool before drying off for lunch at a Costa Rican restaurant on the banks of the La Fortuna River.

Begin the day with a scenic ride up a mountain in an open-air gondola.

Finish the adventure with a guided walk of the forest canopy, where your knowledgeable guide will lead you along natural trails and hanging bridges, pointing out various flora and fauna. 

Hike to one of the natural highlights of Costa Rica, the volcanic Hule Lagoon. The moderate trek begins in Juan Castro Blanco National Park. You'll hike 5 miles (8 km) through the plains bordering the volcanic crater before heading up into the rainforest toward the 136-acre (55-hectare) lagoon. Along the way, enjoy the rich biodiversity of the area. Keep your eyes open for tropical birds, monkeys, and even three-toed sloths!

During this two-hour tour in a private nature reserve just outside La Fortuna, you'll not only have the opportunity to view these slow-moving creatures hanging out in the trees, but you'll also learn all about the sloth's lifestyle, the history of the species, and the importance of sloth protection. Your expert guide will point out two- and three-toed sloths and bring your attention to other noteworthy flora and fauna as you walk along a 1-mile (1.5-km) trail. If you're lucky, you might even spot a mother sloth with her baby.
