Photos of South Cumberland State Park Camping Trails

To echo other reviews, Fiery Gizzard is a rock festival almost the whole way through the gulf. You'll want to be sure footed and a trekking pole or two is a near necessity. This is mainly what makes it "hard" as the elevation changes are pretty minimal. After the climb up the boulders are fewer, and Dog Hole is pretty clear until it drops back down.
The trail is well marked by a combination of tree tags and paint. It gets a lot of traffic so pretty well worn as well.
There are some interesting rock formations, the river has several falls from medium to small, and a couple of good swimming holes. Not much in the way of views even with the leaves off until Ravens Point. Dog Hole has a couple of overlooks as well.
