This is two Islands at high water. One at low pond after Labor Day. There are a couple of places to setup tents or hammocks. There are no services
Double Island Remote Campground Fontana Lake in the Smoky Mountain National Park is available by watercraft only. There are boat ramps in the surrounding area that provide access.
Campground use is via the Check-in Stations, there is one at Fontana Dam Boat ramp.
I have camped there on three occasions. More fun while boating when the water level is up prior to Labor Day. We did see more wildlife including bear when the level was down as they had to travel down to the low level shore.
There is plenty of downed driftwood firewood in the area you have to leave the Island though and forage the shore.
This is a pack it in, pack it out type location. The Rangers typically stop by in the Summer to check your papers. Make sure you have plenty of ice. It's a long way back to Fontana Dam or a local Marina…unless you are in a power boat.
