Best Sloth Tours in Manuel Antonio: Wild Park vs Sanctuary

Updated September 2026 · Manuel Antonio

Our pick: Want a guaranteed, up-close sloth encounter, and don't mind it being a rescue sanctuary rather than the wild? Book the KSTR Wildlife Sanctuary tour. Want the thrill of finding one yourself in the rainforest, with no guarantee? A guided national park tour with a spotting scope is your best real shot.

“Best sloth tour” searches usually assume there’s one answer, there isn’t. A guided walk in the national park gives you a real, wild encounter with no guarantee. The KSTR Wildlife Sanctuary gives you a close, reliable encounter with a rescued animal. Neither is the wrong choice, they’re just different things.

Which to book

  1. Want the thrill of a genuine wild find, and you’re okay with “probably” instead of “definitely”: book a national park guide. Reviewers regularly report sloth sightings, including mothers with babies, but nothing wild is ever certain.
  2. Traveling with kids, short on time, or want a guaranteed close-up: the KSTR Sanctuary delivers a sure thing, plus other rescued wildlife and a genuinely useful look at conservation work in the region.
  3. Want both: they’re only 2 hours each and cover different mornings well. Many visitors do the national park early (best wildlife activity before 9 AM) and the sanctuary in the afternoon.

Common questions

Where is the best place to see sloths in Manuel Antonio?

Two real options: guided walks inside Manuel Antonio National Park, where sloths live wild but sightings aren't guaranteed, and the KSTR Wildlife Sanctuary, a rescue and rehabilitation center where you'll reliably see sloths up close, just not in the wild.

Is it guaranteed you'll see a sloth in Manuel Antonio National Park?

No. Sloths are wild, camouflaged, and often motionless 20+ metres up in the canopy. A good guide with a spotting scope dramatically improves the odds, and many tours report seeing one on most visits, but nothing in a wild park is ever guaranteed.

What is the KSTR Wildlife Sanctuary?

KSTR is Manuel Antonio's only animal sanctuary, running for roughly 20 years on rescue, rehabilitation, and reforestation work. Guided visits let you see rescued sloths, monkeys, and parrots up close, with proceeds supporting the sanctuary's conservation work.

Are the sloths at KSTR wild or captive?

They're rescued and rehabilitated animals, not wild sightings. Some may be non-releasable due to injury and live at the sanctuary permanently; others pass through during rehabilitation. It's a genuinely different experience from a wild park encounter, worth knowing before you book.
