Kayak a stream 200 feet underground on the Deep Darkness tour at Indiana Caverns, part of the Binkley Cave system—Indiana’s longest cave system, and the 7th longest in the country. Each tour begins with a 93-foot climb down a ladder with belay, then continues with another descent down a slope to a subterranean river. The expedition continues upstream by foot, then by kayak as the water deepens. Wear comfortable clothing in layers and sturdy shoes, and the rest of the equipment will be provided for you. Tours last four hours.
Deep Darkness tours are available by reservation only.
