RiverRocks is a fun-filled, family-friendly, environmentally-conscious event that celebrates the Tennessee Valley’s incomparable natural resources, the health benefits of an active, outdoor lifestyle and Chattanooga’s commitment to environmental stewardship and land conservation.

Events and activities include rock climbing, trail running, kayaking, rowing, cycling, off-road biking, hiking and hang gliding for both expert and novice competitors as well as casual participants of all ages. The 10-day event will also feature entertainment such as live music, hot air balloons, river cruises and more. RiverRocks celebrates the majesty of the area’s mountains, rivers and forests by holding many of the festival’s events in some of the Tennessee Valley’s unsurpassed parks and conservancies. These natural resources inspire the kind of outdoor activities that promote healthy lifestyles.

But RiverRocks also exists to help save the abundant land and watersheds set aside through conservancies and land trusts for future generations. In fact, our goal is to ultimately redistribute 50¢ of every dollar collected by RiverRocks to non-profit trusts and conservancies right here in the Tennessee Valley.

Local land trusts and conservation organizations that will benefit from RiverRocks proceeds include the Tennessee River Gorge Trust, the Trust for Public Land, Lula Lake Land Trust, North Chickamauga Creek Conservancy, Cumberland Trail, Lookout Mountain Conservancy, Friends of Moccasin Bend and Reflection Riding Arboretum & Botanical Garden.
