Cascade River Road

Mile 106 off SR 20, in Marblemount

Elevation at road's end: 3660 feet





OPEN

Notice of Road Closure for fall 2014: Cascade River Road will be closed to all public use, 24 hrs/day, 7 days/week, above the Eldorado gate at mile post 20 (three miles from the road's terminus) from September 8 until late October, 2014, in order to perform permanent repairs at the Boston Creek crossing, 1.2 miles from the Cascade Pass trailhead. The Boston Creek crossing has been repeatedly damaged and closed, most recently in August 2013, when over 100 visitors were stranded after a storm caused a sudden road washout.

The maintenance work at Boston Creek will close the road to all vehicle and foot traffic due to the many large construction vehicles that will be using the road and working at the site seven days per week. Public access of any kind to the Cascade Pass trailhead and all Boston Basin climbing routes via the road will not be possible during the closure. Press Release

Currently: The road is open to the trailhead as of June 5.

During late autumn, winter, and spring the road is gated at mile post 20 (Eldorado Creek), three miles before the road's end at the Cascade Pass trailhead. During the late autumn, winter, and spring, the road is open below the gate as snow conditions permit.

This road is vulnerable to washouts during periods of heavy rain, so be prepared, and move to safer ground if need be.

Road is paved to approx. mile 10, then gravel with some potholes and washboards, but generally drivable for low clearance vehicles. Not suitable for large RVs due to steep and narrow sections and some sharp switchbacks. Please drive slowly, road is narrow.
