Nickajack Lake lies on the Tennessee River just west of Chattanooga, and its quiet coves are home to one of the region's more unusual wildlife shows. A cave on its shore shelters a large colony of bats, and in the right season the evening emergence draws visitors and photographers. A guided kayak tour makes the experience accessible, providing equipment, instruction and a route across calm water. It suits beginners and experienced paddlers alike, and it is a gentle way to see a side of the Tennessee River that most city sightseeing misses.
The paddle
Guides provide kayaks, paddles and life jackets and give a short lesson before setting out. The water on the lake is generally calm, which suits beginners. The route follows the shoreline to the cave area, and guides explain the ecology of the bats and the cave, as well as the history of the lake. Boats must keep a respectful distance to protect the wildlife. Birdlife and scenery add interest throughout.
Timing
The bat emergence is seasonal and tied to the warm months, so choose the time of year carefully. Evening departures are generally the ones that match the emergence. Weather and water levels can affect operations. Bring insect repellent, a hat and sunglasses in summer, and a light jacket for the return as the air cools. A dry bag helps protect phones and cameras.
Who it suits
Active families, couples and nature lovers will enjoy the trip. Participants should be comfortable in a kayak and able to follow instructions; age and swimming requirements apply. The tour is a quieter alternative to rafting, offering a relaxed pace and a chance to see wildlife. Check the operator information for the specific schedule.
Making it part of a trip
The lake is a short drive from the city, so you can pair it with a morning at the Aquarium or an afternoon at Raccoon Mountain Caverns. If you enjoy paddling, the operator also offers other trips on the river, including a lock paddle and seasonal wildlife tours. Combine the evening paddle with dinner on the way back into town.
About the bats and the ecology
Bats are vital to the health of ecosystems, eating huge numbers of insects each night, and the colonies that use caves along the Tennessee River are an important part of the region's natural heritage. Caves like this one are protected and sensitive, since disturbance can harm the animals. Guides will explain the rules, such as keeping noise low, avoiding bright lights and staying on the water at a respectful distance.
Watching the bats stream out at dusk is a quiet, memorable event, and many visitors say it is the highlight of the trip. Bring binoculars if you have them, and a camera that works well in low light.
The lake and the river
Nickajack Lake is a reservoir created by a dam on the Tennessee River, and its shores support herons, kingfishers, turtles and other wildlife. The calm water makes paddling comfortable even for newcomers, and the surrounding hills give the lake a pretty, rural feel. In summer, an evening paddle is also a welcome escape from the heat of the day. Remember to check the forecast, since thunderstorms can cancel an outing and strong wind makes paddling harder.
