4.6 (28 reviews)

Overview

Experience the charm of sloths in their natural habitat during a guided walk of a family-run ecological project just outside La Fortuna.

Highlights

  • Observe two-toed and three-toed sloths in their natural habitat

What you'll do

Your adventure begins with a convenient pickup from your hotel in La Fortuna, where you'll be whisked away to a private nature reserve located just 10 minutes outside of town. You'll meet your guide, who'll share some background about the sloth and its habits—and give you a flashlight if you're on a night walk—before you hit the 1-mile (1.5 km) trail.

As you make your way, your guide will stop at red flags that mark where other guides and property staff have recently spotted sloths. Be sure to look up: sloths love to laze about in the trees (the guarumo tree is a source of the sloth's favorite food). Your guide will point out these trees as well as share fancy viewing equipment for an up-close view, as you hike through dense forest and along a river that borders the reserve. Although sloths are solitary animals and spend most of their time sleeping or eating, your guide is an expert at finding them, so you're guaranteed a chance! You'll also look for other wildlife, take photos, and learn a lot about sloths, the local habitat, and other critters you see along the way.

During the excursion, you'll listen to your guide share insights about the importance of sloth protection. Growing threats of habitat loss and due to the sloth's popularity, illegal trade of this species has increased significantly. This ecological sanctuary promotes the animals' security by protecting their natural habitat. 

For an extra treat, sign up for the evening walk to observe nocturnal animals in addition to the possibility of seeing two-toed sloths that are more "active" at night. Then, when it's time, you'll be transported back to your hotel, concluding the activity.

Tips for future travelers

As is true for any outdoor activity in Costa Rica, be prepared for rain and insects.

We saw about 12 sloths, but far away. If you want to be close look for conservatory. Also seeing sloths could be a miss. But the end of trip coffee and snack was nice. Read more

We were picked up by Callidryas Tours for a sloth viewing expedition. For this tour, you do need the guides driving because they search for sloths in the wild while driving the local streets! They have amazing eyes to pick them out of the trees and we stopped multiple times to view the sloths in their natural environment through telescopes. We were able to see both two toed and three toed sloths and also found moms and their babies! Read more
