Tanama River Cave Tubing: Arecibo Karst Canyon Hike, Cave & Float
Explore Puerto Rico’s Northern Karst on a half-day trek and tube tour of the Tanama River—hike old trails, enter low caves, then float through limestone tunnels and spring-fed pools. Guides provide gear, local stories, and pictures for a hands-on outdoor day.
The Experience
Before You Go
Wear grippy shoes
Closed-toe hiking shoes with good traction are essential—river rocks and cave floors are slippery.
Bring ample water and snacks
The tour lasts 5–6 hours and guides recommend high-calorie snacks and at least 1–2 liters of water.
Protect electronics
Use a waterproof case or dry bag for phones and cameras—guides usually take photos but bring protection for personal gear.
Know your limits
Cliff jumping and longer swims are optional; communicate health issues to guides before departure.

Conservation Note
The Northern Karst is ecologically sensitive—stay on established paths, avoid touching cave formations, and pack out trash to protect springs and endemic species.
