Round Mountain Campground is located near Del Rio, TN. The trail is primarily used for camping and is accessible from May until December.
We first were introduced to Round Mountin Campground in 1968 by the local Jim Runnion family.
(It's name then was Rattlesnake Campground but later changed as to not unduly frighten visitors. There are timber rattlers in the part of the country however.)
We lover the area so much that we bought Boomer Den nearby
My wife and I camped here two nights in June, 2013. The campground is reached on a gravel road that is not too difficult to drive on. We camped in Site 6, which has a small stream running beside it. There were few other campers. WARNING: At the time of this writing, no potable water was available, so bring or purify your own. The vault toilets are modern, clean, and well maintained. Bear-proof trash containers are used and detailed instructions are given on how to deal with bears. We didn't see any bears, however, possibly because campers were taking proper food-management precautions. On both nights, we viewed the amazing synchronius-firefly display. If you are there when they are active, be sure to get out of your tent, RV, or whatever around 9:30pm. If you decide to drive to Rattlesnake Gap, know that it's a very narrow road, and pray that you don't meet any cars coming the other direction.
