There are two entrances on the Alcoa Highway side. Take the Northern one that leads to lake and parking area. The southern entrance is closed (the one that leads through a wooded area).
You can enter from Maryville pike to access some of the bike trails and dog park. I know the south gate off of Alcoa HWY has been closed for some time. I don't know the status of the north gate off Alcoa HWY.
