Canyoning in the Lost Canyon, Arenal/La Fortuna

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! You'll also pass several other lagoons on your way before reaching the magnificent Hule, located at the base of the Cerro Congo Volcano. Enjoy a traditional Costa Rican lunch in the home of a local family before returning to La Fortuna.

Embark on an adrenaline-pumping whitewater rafting adventure down the Río Balsa. You'll transfer from La Fortuna to the put-in spot on the river, where you'll receive safety instructions and get outfitted with a helmet and life vest. Then push off into the current and start paddling through rolling Class II and III rapids with names like Morning Coffee and Rock around the Croc. Enjoy wildlife spotting along the way — you'll even have a chance to swim while passing through calmer stretches of the river. 

Get your thrills at Sky Trek, a zip line circuit and aerial amusement park. You'll start in an open-air gondola, rising up over the rainforest and enjoying sweeping views across the mountains. 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.

Venture into Tenorio Volcano National Park for a refreshing hike along the Río Celeste, one of the most stunning natural attractions in Costa Rica. As the legend goes, after God finished painting the sky, he washed his brushes in this river, resulting in its famous electric-blue waters. There's nothing quite like it anywhere in the world! On this guided four-hour hike through the tropical rainforest, you'll stop at Los Teñideros, where two streams of crystalline water come together. You'll also see volcanic furnace vents that expel gases of extremely high temperatures. Take in views of the spectacular Río Celeste waterfall on your descent. Enjoy lunch at the end of the journey.

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. Venturing along these spectacular elevated walkways, up to 180 feet (55 meters) above the rainforest floor, you'll have a chance to appreciate this area's incredible biodiversity, including some of the 350 avian species that live here.

First, you'll head towards the base of the volcano to hike Arenal 1968. This is a network of trails named after Arenal's last major eruption. The event was so catastrophic it transformed some of the region’s topography, and lava fields now dominate one side of the volcano. The trails wind through those lava fields as well as the surrounding rainforest. Along the way, you'll find lookout points featuring prime views of Arenal.

Later in the afternoon, you'll experience the other star of the Arenal Volcano region: La Fortuna Waterfall. If Arenal is the most famous volcano in the country, then La Fortuna is easily the most famous falls. It's located a 15-minute drive from the town of La Fortuna, at the base of the dormant Chato Volcano. The waters here plunge 210 feet into a tropical lagoon, and a 500-step downhill hike provides the opportunity to see the falls from the bottom up. Besides taking photos, be sure to swim and relax in the La Fortuna River below the falls.
