Features -none-


This epic ride is based out of Big Flat Parking Lot, and shows you a great amount of Central Michaux. The tour has all different kinds of terrain where the well-rounded rider prevails. There are fast descents, steep rock chutes, tricky rock gardens, and steep loose climbs. It all goes through the rolling, mountain-laurel covered hills of Southcentral PA.


In the Big Flat parking lot, park in the area farthest from the road. Looking south, the Wildcat entrance is your left-hand side. Ride along the doubletrack for about a mile. The singletrack entrance (which is marked) will be on your left. At the power lines, go straight across and pick up the trail again.

Eventually, you'll come a large sandy roller. On the other side is the real descent. Steep and loose, make sure your brakes work and you aren't running semi-slicks! The many small rocks can throw your bike off-line and you off your bike if you don't know what you are doing. In the middle of the trail, half way down, is a wooden bridge. Go around it to the left and continue descending. At the bottom, there is a fork. To the left is doubletrack, and to the right is singletrack. Go right up EUB Camp Haul Road to the Abigail Trail.

The trailhead (also marked) will be on your right. Climb up the steep grunts of Abby to the ridge. On the ridge there are many small rocks, none that require a good line but a full suspension helps. On the ridge, you'll come to a clearing with different routes. Go left. You know the descent is close when the rocks get big. These require a good line and bike-handling skills.

The Abigail Trail descent is a rocky, flowy descent if you can hold your line and carry speed. This kind of tech-gnar is hard, but going faster over the rocks really helps. At the bottom of the trail, turn right and head onto the Long Pine Trail. This trail parallels the lake and only has a couple roots to worry about. If you are in a rush, take the road, they lead to the same place.

Once you hit Birch Run Rd., turn left and ride on the road for about one mile. Turn right up Greenwood Road Trail. Once you get to the power lines, turn left and cross the field. Once you get to the four-way intersection, veer left and climb to the top of the ridge. There are a couple steep, loose and rocky climbs in there, be ready to whack it into an easy gear.

Once at the top of the mountain, Yellow Ridge Descent awaits you. A fast, wide open trail ready to rip. There are a few scattered rock gardens, but you can just drive your bike through them. At the bottom, turn right on Quarry Gap Rd. and another right onto Locust Gap Trail. This doubletrack brings you back to the four-way intersection.

At the intersection looking north, turn left onto Butterfly Trail. While not steep, there are several rock gardens with rocks that look like they were just thrown there in a pile. They are not planted to the ground. After Butterfly Trail, turn left up Milesburn Road. After about a mile, turn right on Lower Lollipop. For the most part this isn't too technical but there are a couple of steep sections. At the top of Lower Lollipop, make your way to Camps Trail.

Camps is a gradual downhill to Fegley Road. Camps' features are either very technical, or easy. There are a couple of flatter rock gardens with only one precise line through them, and there are also a few steep rock chutes where you need to get back on the bike. After Camps Trail, turn right on Fegley Road for a short bit. Then, turn left and start climbing up Birch Run Road. At the end of a ride, this can be a killer on a hot day so don't drink all of your water beforehand.

History & Background

This is the 20-mile course for the Volvo Endurance Series Michaux Curse of the Dark Hollow. While the event does not attract people from around the state like the Mid Atlantic Super Series, all of the hardcore local riders show up and see who is fastest on the technical rocks instead of all out "roadie sprint mountain bike races".
