The Harmonie Intermediate Loop is made up of the Walnut Connector, Walnut, and Oka Run. This is 10 miles of fun, rolling singletrack great for riders looking to advance their intermediate riding skills.


It is best to access this ride from the main Harmonie State Park parking area, where you'll start on the Walnut Connector. This is an easy/intermediate trail with a little more exposure, roots and climbs than the easy trail. Its 1.8 miles to Walnut Pond, which is a great place to stop for a breath of fresh air.

Veer to the right at the sign for Oka Run, and start a climb up beside the pond. This will take you to a sharp turn at the top. Follow the trail through a nice flowing section with a few vine crossings and a small log drop. The down grade increases a bit and the trail gets a bit tighter in places. Keep riding up and down and all around the forested trail. Coming up is Dead mans curve (most say the name is an exaggeration, some not so much). The trail now has more ups and downs, roots and twists and turns. To the right is a short hike a bike trail (bail-out) to the Walnut Ridge parking area.

You're now heading to one of the longer downhill sections. Drop your seat and get ready for some flow, small jumps and banked turns all the way to the small bridge crossing the creek.

From there, drop some gears and get ready to pedal. You'll climb next to the creek, and keep climbing past it. At the top, cross an old road to enter the goat trail (it feels down hill both ways). At the end, cross the creek. Gear up for the steep climb that takes you to a split in the trail. Left leads to a short steep climb, right leads to a log crossing and rock garden before it meets back up with the trail.

At the next fork in the trail, you can bail out on the right, or keep left on the Walnut Trail. Some tight banked turns send you into some big rollers, before heading up a short but steep climb and on to some nice relaxing trail.

More down is coming up, with technical features such as logs, roots and rolling trail.

When you come to the large ditch crossing, you can carry on or bail out. To stay on Walnut, drop into and up the other side of the ditch. Another long section of flowing wood riding with enough variety to keep you on your toes. After you go over the large log crossing followed by a sharp left through the creek and up the other side, you head down a straight but rolling section.

From here, the trail gets sandy and more technical, with roots and punchy climbs requiring a lower gear. After the real sharp S turn you can shift back up and head down to the picnic table. If its time for a break, this is a nice place, with a view of the Oka Run Creek.

After your break, it's time to get ready for the next long sandy climb. At the top youll find some nice rollers and a jump. After riding along some mild trail you start a descent along some more sandy trail to a creek crossing. Now you follow back along the bank, where you'll cross a large tricky double root crossing.

After this its a short trail ride to Artisan Well Road. Turn left, down Artisan Well Rd. and follow the trail signs to the Oka Run Trail. Continue on the trail with some tight turns and short ascents and descents until you reach the creek crossing, with a bridge.

Turn left at the Y and get ready for a long, tight and sometimes challenging uphill section. After the climb you are now on the ridge line at the highest point of the trail. Shortly, you'll see a sign to your right for the Li'l Rampage - Downhill Trail. Turn left and you'll meander along a moderate descent, to a series of tight downhill switchbacks.

Now its on to the Oka Run creek crossing. For safety, you might want to stop and check this section before proceeding. The Oka Run creek crossing can be a "walk-a-bike" section for some riders. After crossing the creek, a short ride on some lively singletrack, will take you back to the Walnut Pond. Now ride 1.8 miles back on the Walnut Connector to Sycamore Ridge.

Found this ride completely on accident - while traveling, was a pleasant suprise and an enjoyable ride well marked with no killer climbs
