“Some of the best singletrack in the College Forest. Don't miss this Corvallis classic.”— Ty Atwater
After passing several other forest roads on the right (north), you come around a right-hand turn and the road flattens out a bit. There is a sign on the right and the Upper Horse Trail dives off to the left and downhill immediately. Take this and enjoy running down the singletrack and through several switchbacks. The trail comes to a junction that often has a pile of gravel, continue on the singletrack the is overtop of an overgrown road grade.
If you want to head back to the trailhead, jump over to the road to the east (Rd. 610) and turn left for the saddle. Staying on the singletrack will continue to the south and downhill to a junction with Rd. 610. Cross the road and continue downhill. The forest after this junction is one of my favorite in western Oregon; run it and you'll know why. This section of trail is now the Lower Horse Trail. Continue on this downhill until the trail breaks out into an open hillside and meadow.
This is an old orchard and there is a caretaker's cabin up the Jackson creek drainage. The trail T's into another gravel forest road (Jackson Creek Rd.), turn right run a short distance until another forest road leaves to the left, take this fork uphill for a short distance and cross a creek. There is a new trail that crosses the road, turn right on this trail (Lower Dan's Trail to the left and Middle Dan's to the right). This new singletrack is mostly rolling hills for a bit and then crosses a creek on a wooden bridge after a sharp right turn, this bridge and be slick when wet.
After crossing the bridge, the trail heads uphill to a 4-way intersection. There is a new trail on the left, Upper Dan's that cranks up to the top of Dimple hill, take this. Keep breathing, keep those arms pumping and remember there's no shame in going slowly.... ~1.5 miles to the top and ~800 ft of elevation gain and you'll pass a trail on the right, you're almost there!
Top out atop Dimple Hill and take in the view. This is a great spot to stop and chill out for a bit, even if you're just enjoying the view. When you're ready to keep running, you can either head north towards the very top of the hill and take a short, steep and muddy trail, Into the Wardrobe, back to the road, or take the 650 Rd from the top to circle around the back of Dimple. Alternatively, you can turn around down the trail you just came up and take the spur on the left (sharp turn). No matter your choice you'll find yourself on a new forest road, 650 Road, take this downhill to another 4-way intersection, take the right turn on Patterson/600 Road downhill (if you take the left you can connect to the Oak Creek Parking area). Now that you're back on Patterson/600 Road, cruise downhill to the trailhead!
