6 Hidden Gems In The Great Smoky Mountains | Hidden Gems You Probably Didn't Know About
This tunnel, Thomas Divide Tunnel, was designed to keep hikers from having to cross over Clingmans Dome Road. More history on the Tunnel can be found here. How to get here: At the beginning of the road to Clingman’s Dome you’ll see the access gates and during December through around the beginning of March they are closed for the season. If it is not the off-season and the gates are open then you will drive up some and there is a pull-off on the right side of the road right after the access gates. If it is the off-season you can park in the Newfound Gap Parking Area and walk up the road. From the pull-off after the access gate, you will walk under a ¼ mile up Clingman’s Dome road to the stone bridge. The Tunnel is right under that bridge.
