The Itinerary: From La Fortuna to the Heart of the Caves
The tour kicks off early from La Fortuna, with free hotel pickup included, so you don’t have to worry about finding your way. The roughly 45-minute scenic drive takes you through Costa Rica’s lush countryside to the entrance of the caves, located in San Carlos. The small group size (max of 30 travelers) means you’ll get personal attention and have plenty of opportunities to ask questions or just marvel at the surroundings.
Once at the site, your guides—like Diego or Gonzalo—equip you with helmets, lanterns, masks, and rubber boots. These aren’t just for fun; they’re essential for navigating the narrow passages, climbing over rocks, and squeezing through tight spaces. We’ve read that the guides prioritize safety, carefully adjusting routes based on the group’s physical level, which means even those with some apprehension can feel confident with the right guidance.
Walking Through History and Geology
As you step into the caves, you’re immediately struck by the cool, dark atmosphere, contrasting sharply with Costa Rica’s tropical heat above ground. Your guide will share insights into the geological processes that created the caves over millions of years—exposing ancient seabeds, underground rivers, and sea beds that now lie dry.
Among the formations you’ll see are “the papaya,” “the coral,” “the altar,” and “the birthing canal”—names that give a hint of their shapes and the fun of discovering them. Some stalactites and stalagmites hang from the ceiling, forming surreal, otherworldly sculptures. According to reviews, the experience feels like stepping into a movie scene—twisting through tight tunnels, crossing small bridges, and climbing over rocks.
Wildlife and Natural Encounters
One of the real highlights is the abundance of wildlife thriving in these cool dark caves. Expect to see bats, which roost in large colonies, along with frogs and even crabs, all living their quiet lives underground. Several reviews mention seeing sloths during the drive to the caves, an extra little bonus of spotting Costa Rica’s iconic wildlife.
Freida from the reviews comments that “Diego was a great guide. The caves were very interesting. Being mobile/active is a necessity. Definitely bring a complete change of clothes because you’ll get soaked.” This points to the importance of being prepared for a wet, physical adventure.
Getting Wet, Getting Dirty, and Having Fun
This is not a sightseeing tour where you stay dry and clean. Expect to climb, crawl, and squeeze through narrow tunnels**. Many reviewers mention the exhilaration of navigating tight spaces, with some describing it as “some climbing, some squeezing, and some crawling.” If you’re worried about getting dirty or wet, waterproof gear and good water shoes with treads are highly recommended. The tour includes towels and showers afterward, which are perfect for cleaning up before heading back to your hotel.
Dax from the reviews notes, “Tour was very safe. You will get wet! Bring waterproof phone case, and change of clothes. This is a great experience and a must-do.” It’s one of those activities where the physicality is part of the fun, and if you’re prepared, you’ll find it rewarding.
