From Seattle, drive Hwy 20 through the town of Marblemount and on
towards North Cascades National Park. After approximately 50 miles,
the Rainy Pass trailhead will be on the south (right) side of the
road. There is room here for 40 cars, as well as a privy. There is
also a parking area on the north side of the road here which
provides access to other trails.
