Trail Overview

Long Creek (FS 545) is approximately 15.5 miles long. It's open April 16th through December 14th. The starting point for this route turns off the Bear Valley to Lowman Road (FS 582) and ends at Red Mountain Road (FS 515). There is an area large enough for a pickup and ATV trailer to park where Long Creek intersects with the Bear Valley to Lowman Road. The road is a dirt and sand mix with small rocks scattered throughout, but it progresses to being more rutted and rocky within a few miles. There are areas 10 to 11 miles in that have some ruts that are 10 to 12 inches deep, and a corner with significant erosion from water run-off. The vistas are beautiful, especially in the fall when the foliage is changing colors. To reach Red Mountain Road, Clear Creek must be crossed. At the end of September, the water was a little over 12 inches deep and 18 to 20 feet wide at the crossing point. Clear Creek could be much deeper and faster running in the spring and early summer. Be prepared with a chainsaw in case any trees have fallen and are blocking the road. This road is wide enough for full-sized vehicles; however, some of the trails that branch off are only for ATVs, dirt bikes, hikers, and horses. Long Creek Road is located in the Boise National Forest in the Lowman, Idaho area.

The trail has a lot trees across the trail. This is a prior burn area and now the trees are falling throughout the area. I started from the north side and cleared 6 trees but decided to backtrack because I could see many more in front of me.
