Dan's Trail is one of many trails and fire roads within the McDonald Research Forest of Oregon State University. Dan's is about the most popular/well known trail in the forest. It is a well maintained, year round trail that takes you to the top of Dimple Hill. It has many switch-backs and a pretty consistant grade. The base of the trail is about 500' in elevation and the top of Dimple is 1,473'. The trail is broken into three sections: Upper, Middle and Lower. Upper and middle are usually in the best shape, lower is a more technical section that drops down to the end of Middle.
One popular way to ride Dan's is to enter the forest at the Oak Creek Gate and ride up the 600 gravel access road to the top of Dimple hill and then ride down Upper and Middle Dan's trail and then take a fire road back into Corvallis. But there are a wide variety of choices within the Forest which is open to the public year round. Inquire within one of the local bike shops along 2nd St. in Downtown Corvallis for more info.
How to get there:
Once in Corvallis find Harrison and drive west on it to the Oak Creek research station (about 6 miles from downtown, this will get you to the 600 road). Or go north on Highland Drive and follow the signs into Chip Ross Park. A short trail through this park gets you to the bottom of Dan's Trail.
