One of the Great Smoky Mountains most eerie, hidden spots is the Calderwood Lake Train Tunnel, a flooded railroad passage left behind from the region’s early industrial days. Built in the early 1900s, the tunnel carried trains along the Little Tennessee River during railroad and dam work in the remote valley. When Calderwood Dam was completed in 1930, the rising reservoir covered the old rail line and brought the lake to the tunnel entrance.

Today, the tunnel can only be reached by kayak or canoe. Paddlers can enter the low opening and move through cool, dark water surrounded by stone walls. Sounds echo inside, water drips from above, and daylight remains visible at the far end, creating an eerie experience. Depending on water levels, the tunnel may feel narrow and shadowy, so carrying a light is smart should you visit.

Most visitors launch from the Magazine Branch boat ramp in North Carolina and paddle about 2.5 miles to reach it. Calderwood Lake stretches through a narrow mountain valley, with clear water, rocky banks, wooded slopes, quiet coves, and little development along the shoreline. The deep reservoir was formed by Calderwood Dam on the Little Tennessee River and still feels wild and remote. Its calm surface, high ridges, and thick forest make the half-submerged tunnel seem even more hidden.
