Located in the Jackson Creek area of McDonald Forest, Upper Dan's Trail can be accessed from Chip Ross Park. Dan's Trail is the longest trail in the forest and is split into three sections. Upper Dan's Trail is the upper section of the trail, as the name implies. This trail is the only trail in the forest that was named after a person; Dan Petrequin. A memorial plaque for Dan Petrequin is situated atop Dimple Hill. Upper Dan's Trail passes through an area of McDonald Forest that is managed as mature forest for many types of wildlife to call home. Some tree species grown within this area are harvested to produce wood products used for building materials. This section of the trail is 1.6 miles long, with a 250 feet gain in elevation. Dan's Trail is a multiple-use trail open year-round to hikers, bikers, and equestrians. Bikers should be especially careful along this trail and watch their downhill speeds. Dan's Trail leads visitors from Chip Ross Park all the way to the top of Dimple Hill. From Dimple Hill, visitors can enjoy breathtaking views of Corvallis and the Cascades. On a clear day, North, Middle, and South Sister are visible! Make a point to take some time to enjoy this hike and the wonderful views from the top of Dimple Hill!
