Description

See wild sloths in La Fortuna, Costa Rica

These slow-moving, tree-hugging mammals have captivated nature lovers worldwide, and once you see one in its natural habitat you’ll understand why. Sloths spend up to 20 hours a day resting in the canopy, move at a top speed of 0.03 mph on the ground, and have a metabolism so efficient they can survive on as few as 162 calories a day.At Proyecto ASIS we are home to two species of wild sloth: the brown-throated three-toed sloth (Bradypus variegatus) and Hoffmann’s two-toed sloth (Choloepus hoffmanni). Our guided sloth tour walks you through our small private reserve where both species live freely in the trees. You’ll learn to spot the subtle differences between them and understand the role they play in the rainforest ecosystem.
