This is an under-developed trail at Smith Mountain Lake State Park. It is under-developed due to lack of staffing. Thus, the trail exists, but there are no official blazes along the way. The only marking are those by hunters and tags on branches.
The trail states that it is 3.0 miles, but we were closer to 4.0 by the time it was done. It could be because the path was not properly marked, we wandered off trail. This is something that you need to have a GPS (we used phones) to make sure you are going in the right direction. On this trip, the lake level was high due to rain, so we had to also go off trail to walk around the shoreline.
We stopped about 2/3 of the way in to drink some hot tea and enjoy the environment. We were pretty isolated on this trail, so it was very zen while we sat and rested.
