River Gorge Explorer September 2, 2010

Part thrill ride, part nature tour, the Tennessee Aquarium's high speed catamaran offers a riverboat tour to remember. At speeds up to 50 mph, this 70-passenger riverboat takes passengers quickly down the river in a climate controlled cabin and then offers rooftop viewing as it slowly moves through the beautiful and unique Tennessee River Gorge. River cruises last two to three hours. The boat departs 3-4 times a day. Check the website or call for specific times.
