The highlight of the tour is visiting the Charco Azul Caves, where you’ll explore massive limestone caverns with natural formations and Taíno petroglyphs, offering a glimpse into indigenous history. We loved how our guide explained the significance of these markings and pointed out other ecological details. The caves are massive but slippery, so sturdy water shoes are a must—many recommend shoes with good grip to avoid slipping on wet rocks.
Inside the caves, you’ll swim in underground rivers and be surrounded by glistening limestone walls—a surreal experience. Several reviews mention how clear, clean, and refreshing the water was, making the swimming feel like a true nature retreat. Expect to get wet; waterproof cases for phones are highly recommended if you want photos.

The guide will help you navigate the terrain, ensuring safety as you swim through narrow passages.
At Charco Azul, you’ll find a natural pool perfect for relaxing—think calm, warm waters surrounded by jungle. Many enjoy just floating and soaking in the scenery, but for those craving more adventure, cliff jumps are available. Jumping is optional but encouraged, with most reviewers saying it’s not too high and a lot of fun.
Climbing and Navigating the Terrain
This tour isn’t just about sitting in water—you’ll be climbing over logs, navigating rocky surfaces, and sometimes balancing on slippery terrain. Wesley, a guide praised in reviews, often kept everyone calm and encouraged even the most hesitant. Expect a moderate level of physical exertion—good shoes and a positive attitude are essential.
The Scenic Waterfalls
Midway through, the group stops at a beautiful waterfall, often described as a hidden gem. Some reviews note that it’s not as secluded as some might hope, mentioning trash in the area, which is a reminder that even pristine environments need respect and care.
Cliff Jumping and Family-Friendly Fun
For the thrill-seekers, cliff jumps of about 10-16 feet are available. Many reviews highlight how safe and well-guided these jumps are, with guides like Rosa and Juan making everyone feel comfortable. For families, this can be a fun and bonding experience, as long as everyone is physically able and comfortable with heights.
