Follow an underground river through 15–20 million-year-old limestone passages on a 4–5 hour guided spelunking tour from La Fortuna. Expect wet, muddy crawls, fossils, bats, and tight squeezes—this is hands-on cave exploration for travelers in moderate shape.

You step off the minivan into humid air and follow the guide down a slope where the forest closes in like a curtain. The mouth of the Venado Caves breathes cool, mineral-scented air; an underground river hurries away, daring you to follow. Headlamps cut cones of light across slick rock as you duck into passages rimed with stalactites and stalagmites and hear water somewhere deeper, patient and insistent.
