Mountain Biking McDonald / Dunn Forests

*****   Add a review
#36 of 301 mountain bike trails in Oregon
#1,616 in the world

McDonald Forest Maps are sometimes available at these locations. Rides can vary from easy to pretty technical. There are other starting points that require more knowledge of the area and talking to the righr person. As always, please stay on the trails. Most of the trails require uphill riding on fire roads to get there. Some awesome trails in Corn Valley for sure!!

    Fall is a great time for a ride in the forest, it's so pretty that it doesn't matter that it's a little cold or slightly sprinkling.

    Reviewing Dans Trail:

    I enjoyed this ride. I started at chip ross park and was able to connect to the dans trail. A lot of uphill huffing and puffing but the downhilll parts were lots of fun.

    Reviewing Dans Trail:

    The trail is pretty easy, rather smooth surface with lots of turns. These turns are usually not banked and there are a lot of hiker's on the trail so we need to watch our speed. This trail will defiantly work on your lines around a turn. The park is within biking distance of Corvallis so that is really nice.

    Reviewing Dans Trail:

    Probably the best downhill singletrack in the Willamette Valley. Always in great condition. I've ridden it a handful of times in the last few months alone and never get tired of it.

    Reviewing Dans Trail:

    I've just ridden the trail yesterday and it's all clear and well packed. One thing to keep in mind, is that there are some big roots to watch out for. Other than that, its a clean track. Depending on which routes you choose to come down off of chip ross, you can take a straight shot down (not that great) or one of the many other trails which are all alot of fun. Great view at the top of chip ross too.

    Reviewing Dans Trail:

    Unfortunately time constraints limited my trip to only about a dozen or so miles, so this review only pertains to Dan's trail and some other trail linked to it right off the gravel road (I didn't have a map). Dan's climb I didn't find all that bad, the view was grand, and the decent was spectacularly fast. Very smoothe, so extremely low difficulty, be more careful about other riders coming up and horses as well (we saw one). I wish I had had more time to explore. I understand there is some fun stuff out here.
