La Leona Waterfall Hike: Cave Swim & River Adventure Guanacaste

Summary

Hiking riverside trails to La Leona’s hidden cave waterfall in Guanacaste

You’ll trek riverside trails near Rincon de la Vieja with a local guide, scramble over rocks and ladders, cross cool streams, and finally swim into a hidden cave to reach La Leona Waterfall. Expect muddy shoes, new friends from around the world, and that jolt of cold mist on your face when you finally see the falls up close.

What’s the experience like?

I didn’t really know what I was signing up for until we were actually standing at the start of the trail in Guanacaste, just outside Rincon de la Vieja. Our guide, Diego, handed out dry bags and grinned like he knew something we didn’t. The Blanco river was right there—loud and milky from the volcano upstream—and you could smell wet stone and something sharp from the forest. We set off as a group (I think there were folks from at least four countries), everyone sort of sizing each other up but in that friendly way.

The hike isn’t easy, just so you know. There’s mud that sucks at your shoes, rocks that look steady but aren’t, and these ladders bolted into the cliff where I honestly hesitated. Diego kept checking on us—he called me “amiga” every time I slipped—and pointed out birds I never would’ve noticed. At one point we had to cross a stream by stepping from stone to stone, and someone behind me started singing quietly (no idea what language). I remember thinking how weirdly close you get to strangers when you’re all trying not to fall in.

The last part is wild—you pull yourself along a rope through chest-deep water into this dark cave. My heart was pounding so hard I could hear it echoing off the rock. And then suddenly there’s La Leona Waterfall right in front of you, crashing down in this blue-green pool that looks fake but isn’t. The spray is freezing and tastes almost sweet on your lips. Some people swam right in; I just stood there for a minute, trying to take it all in. There’s something about being inside that cave with everyone laughing or yelling over the roar—I still think about it when I hear running water back home.
