Rathdrum Mountain Park is a newer addition to Rathdrum. There is a hiking loop right out of the parking lot and about 10 miles of mountain bike trails that you can loop by taking the forest service road up. The trails are all intermediate rated, and advanced beginners would have a great time on them as well.
Downhill trails include some steeper sections, and a good amount of switchbacks (some more flow and others a sharp turn), and some in the trees sections (watch the handlebars!). The trails are all machine built but still have the single track feel, and they are working on adding another 12 miles of trails in the area.
The Stormking Parkway loop is a great way to experience this park while getting in a 5-mile loop.
