Rock Island State Park is located just north of McMinnville, TN. Once you leave the town, it's about a 25 mile drive on Sparta Hwy/Hwy 70s. You will see the signage for the park once you get close. To park close to Twin Falls, you have to cross the damn and take the first left. That road dead-ends into a parking area right next to the falls.
This was taken on a perfect Autumn morning at Rock Island State Park. My friends and I that were shooting that morning agreed that this was THE perfect set of conditions....great flow in the falls, Autumn color and a nice foggy veil to add depth and mystery to the scene.
