See Sloths & Blue River Waterfall in Costa Rica

Summary

Wildlife Watching & Waterfall Adventure in Guanacaste

You’ll swim under a hidden waterfall, hike to a surreal blue river, and spot wild sloths—all in one day. It’s a real taste of Costa Rica’s wild side, with local guides who know every shortcut and secret spot.

What’s the experience like?

Sunlight filters through the trees as we pull up to Llanos de Cortés Waterfall. The air smells faintly sweet, almost earthy, and you can hear the water before you see it. The falls aren’t huge, but there’s this wide pool at the bottom—locals sometimes bring their kids here to cool off. I dipped my toes in first (it’s colder than you’d think), then just went for it. Some folks were cliff jumping off the rocks to the left—our guide, Daniel, pointed out the safest spot if you’re feeling brave. I just floated on my back, looking up at the green canopy overhead. It’s a good place for photos, but honestly, it’s better just to soak it all in.

Next up: the hike to Blue River waterfall. It’s about an hour, not too tough, but you’ll want shoes with grip—some parts get muddy if it rained the night before. The trail winds through thick forest, and you’ll hear birds you probably can’t name (I sure couldn’t). When you finally reach the waterfall, the water really is this wild blue color—almost milky. Our group just stood there for a minute, nobody talking. It’s one of those places that feels kind of unreal. I snapped a few pictures, but mostly just sat on a rock and listened to the water crash down.

The last stop is what everyone was waiting for: sloths in the wild. There’s a short trail, maybe 20 minutes tops. Our guide had this knack for spotting them—he’d point up and suddenly there’d be this little ball of fur hanging out in the branches. Sometimes you see two or three if you’re lucky. They move so slowly you almost miss them unless you’re patient. We even saw a baby clinging to its mom. The guides know all about their habits and favorite trees. If you want a selfie with a sloth in the background, this is your shot (just don’t get too close—they’re shy).
