Great Smoky Mountains National Park, TN · NC
A remote creek connector with slippery crossings and a steep ridge climb.
Overview
Cold Spring Gap Trail is a remote, roughly 4-mile one-way connector between Hazel Creek Trail and Welch Ridge Trail. Going from Hazel Creek up to Welch Ridge means about 2,300 feet of climbing. This is a backcountry link, not a short walk from a parking lot: one documented approach to the Hazel Creek junction is a 6.7-mile hike from campsite 86 on Fontana Lake. Allow about four hours for the connector, then add the miles needed to get in and out. I’d save it for a planned backcountry route. Overnight camping requires a permit and advance reservation, and dogs aren’t allowed on this trail.

About 0.3 miles from the Hazel Creek junction, the trail crosses Hazel Creek at a ford roughly ten feet wide; rusted auto parts sit nearby. The sandy bottom offers firmer footing than the slick rocks, but water depth changes with rain. Don’t cross if the water is high.
Switchbacks lead away from the creek past old homesites. Cold Spring Branch appears around 1.2 miles in, near a stone wall, and the upper trail crosses the branch several more times. Expect rocky, muddy footing and a steep climb. From the Welch Ridge end, this same stretch is a steep descent into the valley. The separate High Rocks Trail branches at the ridge junction; it isn’t part of the Cold Spring Gap line.
The homesites and stone wall are reminders of earlier settlement, though no dates or occupants are established. Spring wildflowers are a highlight, but the species along this route haven’t been reliably identified.
