Float through limestone tunnels and spring-fed pools on a 5–6 hour Tanamá River eco-adventure. This guided trip blends hiking, cave passages and calm tubing in Puerto Rico’s karst country.
More ways to explore the area's outdoor wonders
You step off the trail into a pocket of humid air where limestone walls rise like weathered ramparts and springs leak cold into a slow, green river. Guides clip on helmets and life jackets, tell a short history of the place, and the group eases into the current: the river takes over, carrying you through cave mouths, past cliff faces streaked with mineral veins, and into pools that invite a long, cool float.
