Trail shared by Liz

A nice, chunky loop that shows off the best of what Harold Parker State Forest has to offer.


E-Bikes Unknown

Features -none-


A good sampler of the trail network that features some highly technical rock moves. This route is loaded with alternative/advanced lines, rock features, and challenging terrain! Rocks and roots galore!

Need to Know

Bikers must remain in control of their bike at all times and should announce themselves as they approach hikers and horses to avoid startling other users. Hikers yield right-of-way to bikers in this area but please slow down and be respectful when passing.


Heading east out of the new parking lot on Jenkins Road, take the first right onto the singletrack to follow Root Ball. Before long, take a left onto an unnamed trail (here referred to as Harold Parker Trail), which will take you north to the Yellow Diamond Trail. At this intersection, turn right and follow the Yellow Diamond Trail for a little less than a mile. Turn left onto Road NA17 then take an immediate right onto Road NA16 to a junction with the Acorn Trail. Take the Acorn Trail west to the junction with Upper Salem Pond Road and head south and west on the NRT.

About 2.6 miles into the ride, the NRT rejoins the Yellow Diamond Trail. Take a left on the Yellow Diamond Trail (you'll need to ride a short distance on Salem Pond Road). Follow the Yellow Diamond Trail along the banks of Salem Pond to where the trail closes its loop. Turn left to head down either an unnamed singletrack or Bradford Pond Road, before veering right back onto Root Ball.

Take Root Ball all the way back to the start of the ride, crossing Berry Pond Road and passing the parking lot to jump onto White Rabbit Trail. Take White Rabbit Trail north past the swamp to its end at the junction with Bay Circuit Trail. Turn right on Bay Circuit Trail to its junction with Berry Pond Trail onto which you'll turn right and head south. Take a right to take the short connector to rejoin White Rabbit Trail and head south back to the parking lot.

This is a great afternoon/evening ride with plenty of challenges available for riders of all skill levels. This can be a pretty technical ride, and riders will need to be able to navigate an abundance of rocks and roots. Beginners/intermediates will surely need to walk some sections, but overall it is an excellent challenge.
