A bilingual guide will lead you on a nature walk through the Ecological Park & Butterfly Garden Danaus on this half-day tour. You'll have the chance to spot tree frogs, caimans, monkeys, sloths, and a wide variety of birds as you follow your guide on a nature trail. Stop at botanical gardens, a butterfly garden, and a wetlands area that serves as a bird nesting site. Finish the tour with a visit to a Maleku cultural center to learn about Indigenous traditions and environmental practices.

See sloths in their natural habitat on this family-friendly excursion! 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.

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.

Experience the rainforest after dark on this unique guided excursion to Ecocentro Danaus, a private ecological reserve near La Fortuna. As the sun goes down, you'll venture into the jungle, exploring this haven for plants, insects, reptiles, and other nocturnal animals. Highlights your guide will point out along the way include bats, spiders, sloths, snakes, and some of the reserve's many native frog species, including the brightly-colored poison dart frog, one of the planet's most poisonous frogs. Since the reserve is closed to most groups by night, this is an exclusive opportunity to see how the rainforest transforms after dark.

Embark on a two-hour hiking excursion along the "sloth trail" with a bilingual guide. Discover the tropical forest while spotting sloths, birds, and reptiles in their natural habitat.

Explore Juan Castro Blanco National Park, one of the lesser-known and least visited of Costa Rica's national parks, and its resident wildlife with a naturalist guide. Nicknamed "the National Park of Water," this biodiverse tract of rainforest and cloud forest is northern Costa Rica's primary water source. The park is a highly regarded place for bird-watching: during your hike, you may spot the resplendent quetzal and the clay-colored thrush. 

Get an "early bird" start for this popular bird-watching excursion to Arenal Mundo Aventura Park. There's a good reason for the early wake-up time: the park is home to a stunning variety of birdlife, and most species are at their most active in the morning. Follow a naturalist guide through the park's different ecosystems, including a new tree-planting zone, open pastures, regenerating forests, and small streams. The mix of terrain allows for optimal bird viewing. You'll likely spot the great kiskadee, tropical kingbird flycatchers, black-cheeked woodpecker, and possibly the red-billed pigeon. An included breakfast follows the birding hike.

Visit Proyecto Asis, a wildlife rehabilitation and rescue center. A naturalist guide will lead you on a tour, introducing you to the resident animals and sharing their stories. You'll likely see anteaters, monkeys, snakes, parrots, sloths, and more. 
(Because the center's goal is to release as many animals back into the wild as possible, the wildlife present at the center is subject to change.) During your visit, you'll also learn about conservation and sustainability.
