Mount Rainier Passes to Open June 11

Posted by Loren Drummond at May 01, 2018 06:52 PM |

Mount Rainier National Park expects to open Chinook Pass and Cayuse Pass by June 11, and other lower-elevation facilities will begin to open in mid-May.

One of the key things to know about hiking in Washington is that a few routes well-traveled by hikers in Washington are only open seasonally. In Mount Rainier National Park, Chinook Pass and Cayuse Pass both close in the winter, and reopen once they have been cleared of snow.

Today, the park announced that they expect to open both SR 410 Chinook Pass and SR 123 Cayuse Pass by June 11, after clearing snow and getting a jump start on repairing a quarter mile of SR 410 near milepost 64.

"For several years, motorists have experienced rough road surfaces at this location related to a slow moving and deep-seated landside," the park reported.

The road work will continue through late June, and hikers should expect short delays with alternating one-way traffic between mileposts 64 and 64.5.

Other key opening dates at Mount Rainier National Park

The park also announced the following target opening dates for entrance and facilities:

May 11-  The park’s southeast entrance near Packwood will open, providing access via SR 123 to the Grove of the Patriarchs area. Portable restrooms will be placed at the Grove parking area until the primary restrooms are opened for the season.

In Other (road) news

The crews dodging avalanches and plowing Highway 20 in the North Cascades have estimated they'll open the road on Friday, May 11 at 10 a.m., and you can follow their progress.

Many Forest Service roads remain closed and gated to vehicles. Their opening dates are also variable, depending on the winter snowpack and spring runoff damage. And of course, the road to Artist Point likely won't open until July.

Hike planning tips

  • Once these snowbound roads and passes do open, the snow will likely still be quite deep in the area and may be for some time. So hike prepared and check trip reports for trail conditions before heading out.
  • No matter where you are planning to hike, it is a good idea to check road conditions along your entire route before you head out. The best way to know if you can get where you are going is to check with Washington State Department of Transportation (who does a good job with their Twitter feed) and/or the land manager directly.
