This southwestern corner of Mt Rainier National Park is its most developed (and hence most visited) corner. Here you'll find the park's only lodging, the only year-round road and the gateway settlements of Ashford and Copper Creek that offer plenty of useful park-related facilities and lodging.
White River Entrance
Rainier's main eastern entrance is the gateway to Sunrise, which at 6400ft marks the park's highest road. Thanks to the superior elevation here, the summer season is particularly short and snow can linger well into July. It is also noticeably drier than Paradise, resulting in an interesting variety of sub-alpine vegetation, including masses of wildflowers.
Just outside the northeastern corner of Mt Rainier National park lies Crystal Mountain Resort, Washington's largest ski area, 39 miles east of Enumclaw off Hwy 410. This is the state's only ski 'resort' with various overnight accommodations at the base. However, in reality, Crystal still functions primarily as a day-use area due to its relative proximity to Seattle and Tacoma.
Carbon River Entrance
The park's northwestern entrance is its most isolated and undeveloped corner, with two unpaved (and unconnected) roads and little in the way of facilities, save a lone ranger station and the very basic Ipsut Creek Campground. But while the tourist traffic might be thin on the ground, the landscape lacks nothing in magnificence or serendipity.
Adams is the state's forgotten peak, the second tallest of Washington's Cascades but a mountain that has long been overshadowed by Rainier's height and St Helens' explosive power. Nonetheless, Adams remains an impressive mountain; the lack of a major glacier on its south side allows for a comparatively easy, nontechnical ascent for aspiring peak-baggers.
