Features -none-


The 36-mile Rothrock TrailMix course provides a combination of some of the best trails within Central Pennsylvania's Rothrock State Forest. The Nittany Mountain Biking Association (NMBA) has been hard at work over the last few years rerouting many old legacy trails to more sustainable trails that are even more enjoyable to ride! NMBAs hard work has turned Rothrock State Forest into a mountain biking destination.

The TrailMix has it all - ridge tops, technical trails, awesome descents, grueling fire road climbs, and some new machine-built trails that are smooth, flowing, and fast. This 36-mile ride is nothing short of Epic. It will challenge even the most seasoned mountain biker. Expected ride times for a pro-rider are around three hours, and up to six hours for the experienced recreational rider.

Happy Valley Biking promotes the Rothrock TrailMix race annually - the second Saturday in June - and proceeds are donated to the Nittany Mountain Biking Association (NMBA).

Need to Know

The ride begins at the Galbraith Gap parking lot, just passed the Tussey Mountain Ski Resort. There is ample parking available. Spring Creek runs just below the parking lot and is a great place to cool off after the ride.


Begin at the south end of the Galbraith Gap parking lot and ride up Black Gum Trail. Now, turn right and cross the bridge and turn left on to Galbraith Gap Trail. When you pop out onto the road, look ahead and to your left and you'll see Lonberger Path (reroute). Give it a climb up the beautiful rock armored section.

When you get to the top, take a right onto Three Bridges Trail. Here, you'll have three bridges and a beast of a rock garden to start off your Epic ride. If you were able to climb the rock armored trail and clear the three bridges and rock garden you are in good shape for what to expect along the rest of the ride.

If you needed water for your pack, the spring after the three bridges and before the rock garden is a great place to fill up to start your ride.
After you clear the rock garden, continue your climb up Laurel Run Rd. Turn right onto Bald Knob Ridge Trail for a short distance, and then turn left onto Green Shoot.

Initially you'll encounter rocks, rocks, and rocks, but the trail will smooth out as you climb. At the top of Green Shoot, you'll make a left to rejoin Bald Knob Ridge Trail, a rocky ridge trail with many tombstone style rocks. Your hard work will be rewarded as you begin your descent down Maguire Trail.

Turn left onto Lower Trail - the heart of Shingletown and weave along Roaring Run stream. If you visit in the spring, the mountain laurel will take your breath away. Turn right onto Laurel Run Rd and then take a left on the dirt road that leads to Little Flat Tower.

New Laurel Run Trail, an exhilarating technical descent, will be on your right. Turn left onto Laurel Run Rd, descending for a mile, then take a left and head up, up, up Bear Gap Rd, where you can stop for water and enjoy the view! A half-mile past Gettis Ridge Road, you'll see Croyle Run Trail. Croyle will be on the left and is a very fast and technical one-mile descent. Croyle will leave your arms screaming even with a full suspension 29er.

At the bottom of Croyle, you'll take a left on Beidleheimer Rd. In a half mile, youre going back up, turning left on Gettis Ridge Rd Trail. Do not stop at Wampler Road, but continue to climb Gettis Ridge Road to North Bear Meadows Rd. Time to give the legs a break. Down you go, stopping at another magnificent view on the way down if you wish.

Two miles later, you'll be turning right onto Bear Meadows Rd for a few hundred feet, setting up your entrance to Tussey Mountain Trail, an awesome, most spectacular ridge top trail with rocks, short climbs, flow, and so much beauty you'll be planning your next trip before you even leave! Pass the beer tap and continue down Tussey Mountain Extension, a very fun, fast descent on a narrow bench cut trail.

Turn left onto Leniency Trail, a smooth and fast, machine-built trail with banked berms. As your descent slows, you'll come to a small meadow and a trail intersection with Bail Out Trail, stay on Leniency Trail and come back up to Tussey Mountain Extension and take a left.

Follow the trail out Treaster Kettle Rd and turn left. In a half mile, turn right onto Thickhead Mountain Rd and climb until you see the sign for John Wert Trail. Ride down this gated camp road and across the gas line where the beauty of John Wert begins, a flat, technical trail that has two large rock gardens that can prove challenging to even the best riders. Unfortunately, John Wert comes to an end, where you'll turn right onto Bear Meadows Rd.

Take a left at North Bear Meadows Road, and then a right onto Upper Lonberger Trail. Upper Lonberger is rocky and technical, but Lower Lonberger Trail is fast and fun.

You'll be back to where you started your initial climb, enjoy your descent down to the parking lot.

Reading prior riders' comments, bumped up tire width. 2.4 front / 2.3 rear -> 2.6 front / 2.4 rear. Improved both traction and shock absorption. Both were very helpful for all the rocks. Oct 6, 2018
