Although the current trail condition and accessibility make Bluff Mt Tr172 and Starway Tr175 unsuitable for biking, Bluff Mt Tr172 is a challenging OAB hike on eastern Silver Star ridgelines, connecting to the Silver Star Tr180 trail system.
Ding: FR4100 is a very rough road and can take 2hrs to reach the Bluff Mt Tr172 TH. In general, the area roads and trails appear abandoned by the forest service.
Starting from the upper Starway Tr175 TH, all the climbing is on FR4100, so although there is substantial elevation gain it is a relatively moderate hike.
The loop can be extended by adding Chinook Tr180B, Tarbell, Sturgeon Rock Tr180C and Silver Star Tr180.
Silver Star Area Trails
Near Vancouver, the Silver Star area trails are popular with hikers, bikers and equestrians. As a result, the trails get a lot of use and receive good maintenance. There is enough terrain variety and trail length to create decent weekend destination rides, but not the kind of epic rides found further into the Gifford Pinchot National Forest.
The Silver Star TH makes a good shuttle point as well.
Nearby Indian Pit Tr180E offers some archaeological scenery as well.
Nearby Bells Mt is a good trail for those seeking easier terrain, but good shuttle opportunities on the other trails creates opportunities for advanced beginners.
