Lake Easton State Park is a forested, 516-acre year-round camping park with 24,000 feet of freshwater access on the shores of Lake Easton in the Cascade Mountain foothills. The park has beautiful mountain views and hiking trails to explore in the summer and cross country and snowmobiling trails to enjoy in the winter. The park's location also allows for snowy winter-sport opportunities. Year-round recreational opportunities abound in this beautiful park, which offers a swimmable beach and a boat launch.

The park is located within a glacial valley in the Washington Cascade Range. The Northern Pacific Railroad built a tunnel through the Cascades beginning at Easton.

A Discover Pass is required for vehicle access to Washington state parks for day use. For more information about the Discover Pass and exemptions, please visit the Discover Pass web page.

The park has 90 standard campsites, 45 full-hookup sites, two hiker / biker sites, one dump station, four restrooms three ADA, and four showers two ADA. All sites are in a wooded setting. Most tent sites are near the Yakima River, and most RV spaces are near Lake Easton. Tents must be placed within the designated tent pad. The park can accommodate RV units up to 60 feet in select sites. Some sites will accommodate tip-outs.

Lake Easton's campgrounds are set on the north side of the park close to Interstate 90. As such, they are subject to highway noise. Earplugs are recommended for light sleepers.
