Here, by a barn on a hill is the entrance to the trails up Bald Hill. If you are truly an animal you can try to tackle this before continuing on but I wouldn't suggest it.... Check out my other guide for this if you are interested.

7. Bald Hill Parking Lot

Just before the bridge over the creek to the parking lot take a left and continue on a dirt path alongside the road past a cow pasture.

8. Oak Creek Drive

Take a right and then a left to head north on Oak Creek Drive. There is no bike lane but the shoulder is big and locals know this a popular bike route so it's not very dangerous.

Bare right to continue on Oak Creek Drive.

10. Homestead Trail

From the parking area here just before the trail signs take a left into the woods onto the Homestead Trail.

Head left onto a single track bike path that will take you to the top of McCulloch Peak.

13. McCulloch peak

Don't bomb down the trail though as you will soon exit back onto Road 600 again to head towards Lewisberg Saddle.
