[4k] Gangplank Falls is Fun Little family Raft water ride in Disney's Typhoon Lagoon at Walt Disney World.
"Get swept away by rushing rapids down a 300-foot-long waterslide aboard a 4-person inner tube. Big kids, teens and adults can all climb in and whoosh through rocky caverns, beneath drenching waterfalls and under rustic wooden bridges on their path down the mountain—all while rotating this way and that and banking from side to side." - Walt Disney World website
