There is a great view here of Woody Mountain and the Mount Jumbo Wildlife Management Area. This double-track road is pretty smooth and most bikes can handle the terrain pretty easily.

The Kim Williams Trail is a super popular trail in Missoula. It follows along the river the majority of the way, but it is often times tucked in the trees without a lot of views. The section of trail furthest west is a really smooth paved and dirt path. As you get further east, the trail narrows and becomes bumpier. Some choose to ride a bike with more suspension for this rougher section, but most touring bikes can handle the trail just fine from start to finish.

McCormic Park marks the western terminus of the Kim Williams Trail and the eastern terminus of the Milwaukee Trail. The park has some playing fields, open space, picnic areas, and is nestled up right next to the river.

Deer Creek Sneak is labeled as a "Green" mountain biking trail, but it is popular for gravel bikes and bike touring as well. The trail climbs steadily from Deer Creek Road to the intersection with the Pattee Canyon mountain biking trail system. This can be a fun, fast downhill trail to ride.
