Carbon River Road | Visit Rainier

Carbon River Road

The Carbon River road was washed out by the 2006 flood and is open to vehicles only to the Carbon River Ranger Station at the park boundary. Bicycle and pedestrian traffic are permitted on the remainder of the road inside the park. The Carbon River Entrance is reached via the Carbon River Road, off  State Route 165.

During the winter season (Nov 1 – May 1), all vehicles are required to carry tire chains when traveling in the park. This requirement applies to all vehicles (including four-wheel drive), regardless of tire type or weather conditions. Review the Tire Chain Frequently Asked Questions for more information.

OPEN to pedestrian and bicycle traffic only. No vehicles are permitted beyond the park entrance; bicycle and pedestrian traffic only.

NOTE: Spiketon Creek Bridge (aka Pioneer Way Bridge) on State Route 162, outside of the park just west of Buckley, WA, along with the route to the Carbon River Entrance, is CLOSED permanently. Motorists and bicyclists can follow a detour route onto Pioneer Way East to Mundy Loss Road to SR 410 and back to SR 165; see detour map. Or from South Prairie, take AP Tubbs Rd to Johns Rd E to SR165; see alternate route map. The Foothills Trail under the bridge will remain open.

 NOTE: Due to a large number of fallen trees, the Carbon River Trail (former road) is temporarily impassible for bicyclists and challenging for hikers. Thanks for your patience while crews work to clear the road. (updated 1/22/21)
