Belize: Cave Tubing at Nonoch Che’en Caves
Cave tubing at Nonoch Che’en caves: you hike through jungle for an hour with a large inflated tire-like tube, plop yourself into it in front of a cave entrance, and float through incredible sights of narrow passages, underground waterfalls, terraces, and bats zipping around you. There are two long caves with river running through them with opening and skylights abound.
