Requires a high level of cardiovascular fitness, good balance, and comfort with scrambling over rocks and roots.
A punchy, technical hike and swim near Tamarindo: 3 km of rocky trail, stream crossings and a plunge pool that makes the effort worthwhile. Expect a small-group, safety-first outing with local guides and a typical Costa Rican lunch.
You step out of the air-conditioned van into a pocket of heat and green; the truck hums away and a ten-minute dirt ride bucks you to a small trailhead where the forest closes behind you. The first steps are forgiving — gravel underfoot and the chatter of tropical birds — but the trail quickly tightens, roots and boulders forcing concentration. La Leona announces itself in stages: a braided stream daring you to find a foothold, vines hanging like handholds, and, finally, a broad blue pool where the river drops into a hollowed rock bowl.

Water shoes or lace-up trail sneakers with good tread are required — rocks and roots make the trail slippery.
Pack a towel and dry clothes in a waterproof bag; you’ll want to be comfortable for the return ride.
Carry at least 1–2 liters of water and take breaks before tricky climbs; the hike is short but intense.
Guides control access to steep sections and provide life belts — follow instructions for safe river entry and exit.
The trail follows waterways carved through volcanic rock; local families have long used these rivers for freshwater and small-scale agriculture.
Operators run small groups to reduce erosion and limit noise; stick to the trail and avoid leaving trash so pools and fish habitats stay healthy.
Grip and quick-drainage for wet rocks and stream crossings.
Protects against sudden tropical downpours and keeps you warm after swims.
You’ll want dry layers for the return van ride and to avoid chill after the swim.
Keeps bugs away on shaded trail sections and protects skin near reflective water.
