“An easy trail with switchbacks and smooth enough terrain for lots of enjoyment.
— Chris Gibbs
From the guard shack on the west end of Oak Ridge, park your car and take your bike around the gate (yes you're allowed to.) After a small incline and turn, the trail will start on your left going up and back towards the start of the gravel. After a .1 to .2 mile section, this trail segment will dump you off looking at the turnpike. Take a right and head straight for the road, cross it and there is the entrance to the other segment of the trail.
This segment lasts about a mile and will set you down on a gravel road named Quarry Rd. A left will take you straight back to the turnpike, where you can use the road/sidewalk to return to your vehicle. You could take a right and find out why it's named Quarry Rd.
If you continue past the end of this trail, taking a right and going maybe a mile to further, go through some challenging trail (not entirely rideable) and find the hidden cove. The water is cold, clear, and refreshing. If you want to take the long way, instead of going straight through the trail, go right, up and around. You'll pass a trail on your right that is off limits to bike. You have been warned.
