North of Boise in the Ridge To Rivers Trail System, the Upper 8th Street Trails were built for OHV users. The Trail #4 / Trail #6 Loop is a challenging route. This route is open to OHVs but may not be suitable for the new rider. It is a difficult mountain bike ride in either direction. Trail #4 provides access to the Boise Ridge Road and beyond for those vehicles that are street-legal.
- 8th St. Parking Area provides access to the OHV trails and Hulls Gulch. (recommended).
- Upper Interpretive Trail parking is a small site 4 miles beyond the 8th St. Parking site.[rr]
- Upper OHV lot - A small area 4.75 miles beyond 8th St. lot accesses trail #4.
Overall, Upper 8th Street Trails is the 6th most popular OHV & 4wd jeep trail of all 12 OHV routes in Idaho.
