Davidson Gap, Little Cataloochee Trail, Great Smoky Mountains National Park, 22 May 2011. The Little Cataloochee Trail connects the cove known as Big Cataloochee with the Cove known is Little Cataloochee. Both coves were populated before the creation of the national park. It is possible to drive into Big Cataloochee, but the only way into Little Cataloochee is to hike in from one end or the other of the Little Cataloochee trail. Davidson Gap is at the top of the ridge separating the two coves.
