Outdoor Chattanooga hosts a guided and equipped canoe trip to Nickajack Cave, where thousands of endangered gray bats come each summer to raise their young. We will begin with essential canoeing instruction for the novice paddler and set out for a short paddle to the mouth of the cave at dusk and watch the bats fly to start their nightly feeding. Boats anchor just off the cave entrance to view the emerging bats. Visitors should be careful not to shine beamed lights of any kind on the bats during emergence as it affects the bats and the viewing. A short return paddle in the twilight tops off the experience. No public admittance within the cave is allowed.
