DORADO RIVER TUBE FIELD GUIDE
Tubing the Underground: Cave Rivers and Jurassic Rainforest of Dorado
A Caribe Adventures outing from Dorado that packs 4–5 hours of river tubing, cave passage, canyon hiking and waterfall jumps — this guide explains what to expect and how to prepare.
Tubing the Underground: Cave Rivers and Jurassic Rainforest of Dorado.
Set deep into Vega Baja’s limestone, the Rainforest Cave Tubing Adventure threads river channels through Charco Azul and the Arenales caves, then climbs into a green, canyon-cut rainforest. Expect a day of subterranean passages, river tubing, steep trail sections and occasional jumps into clear pools — an experience that reads like a compact Jurassic excursion through water and stone.
