Full-hookup park on the I-90 corridor just east of Snoqualmie Pass with 45 utility sites, mountain lake views, and hiking access. Note: I-90 and rail noise.
Lake Easton State Park is the most convenient full-hookup campground along the I-90 corridor between Seattle and Spokane, perched on a scenic alpine lake just 15 miles east of Snoqualmie Pass. Forty-five full-hookup sites accommodate RVs up to 60 feet with ADA-accessible restrooms, showers, and a dump station. Mountain views from the campground are excellent. Important note: the park sits between busy I-90 and active railroad tracks with several freight trains passing at night. Open May through October.
Lake Easton State Park sits at 2,200 feet in the Yakima River headwaters just below Snoqualmie Pass — one of the I-90 corridor's most important ecological crossings — where the river begins its descent from the Cascades through a managed reservoir flanked by old-growth forest. The John Wayne Pioneer Trail passes through the park on its 56-mile route across the Cascades, converting an abandoned Milwaukee Road rail corridor into a trail that follows the watershed divide between Pacific and Columbia River drainages. The Yakima River above Easton Lake is designated Wild and Scenic and is one of Washington's top blue-ribbon trout streams, while Snoqualmie Pass above provides access to the Alpine Lakes Wilderness and its 700+ glacial lakes within a 10-mile drive.

Loop A sites near Lake Easton (1–35) are the most desirable for water access and fill first — book the closest-to-lake sites 6 months out. Loops B and C have full hookup sites with good utility for longer stays. Easy I-90 access makes this popular for Cascade escapes. The lake is excellent for kayaking and stand-up paddleboarding. Snowmobile and cross-country ski access in winter.
