Nickajack Lake in Tennessee offers paddlers a scenic reservoir experience with opportunities for wildlife viewing and historical exploration. The lake covers 10,900 acres and is part of the Tennessee River system. Access points include the Shellmound Campground boat ramp on the north side and the Maple View Public Use Area boat ramp on the south side.

A popular paddling destination is Nickajack Cave, located about 2 miles from Shellmound Campground. The partially flooded cave houses a large colony of endangered gray bats, best viewed at sunset from late April to early October when an estimated 100,000 bats emerge to feed. Paddlers can explore the cave entrance by canoe or kayak, but should be mindful of the sensitive bat habitat.

The lake's undeveloped shoreline provides a natural setting for paddling, with upland hardwoods and pines lining the banks. Wildlife sightings may include osprey, river otters, and occasionally bald eagles. The surrounding area marks the beginning of the Tennessee River Gorge, often called the "Grand Canyon of Tennessee".

Paddlers should be aware of potential hazards like boat traffic and changing weather conditions. During one reported trip, paddlers had to seek shelter due to an active lightning storm. The lake is also used for commercial barge traffic.

Amenities for paddlers include campgrounds, swimming areas, and boat ramps at locations like Shellmound and Maple View. Some areas offer bathhouses and picnic facilities. Fishing is popular, with species like bass, crappie, and catfish present.

The best time for paddling is generally late spring through early fall. Water activities are most enjoyable from late April to early October, coinciding with the bat viewing season. Paddlers interested in Nickajack's history can research its past as a Cherokee settlement and its role during the Civil War, though much of this history now lies underwater due to the dam's construction in 1967.
