I haven't rode it yet. Went to the park with the wife and her beach cruiser so . . . didn't ride the trail but I heard it was pretty sweet.
From HWY 78 Take Veterans Ave. Exit to the right. Follow signs to Elvis Presley Lake. Once through the gate stay to the right and it's on the right almost immediately.
