- Lake Easton State Park covers 516 acres with 24,000 feet of freshwater shoreline on Easton Reservoir and 2,000 feet on the Yakima River. A boat launch ramp and dock are provided at the upper end of the park.
Of special note are the 37 miles of trail for winter public cross-country skiing on State Park land and adjacent US Forest Service and private lands.
Park facilities include 92 standard sites, 45 utility sites, eight group camp sites (50 people), four restrooms, 40 picnic sites, playground equipment and a trailer dump station. This park is on the Campsite Reservation System.
Recreation - Camping, picnicking, freshwater fishing, boating, hiking, swimming, mushroom hunting, and playground activities are popular summer activities in the park. In the winter snowshoeing, snowmobiling and cross-country skiing are enjoyed.
Climate - Washington's climate varies with each region. The Cascades split the state and alter weather patterns. Moisture bearing winds coming from the west give generous amounts of precipitation to the mountains, with wintertime snow above 3000 feet. This area has an average annual precipitation of 104 inches and an average wintertime snow depth of 87 inches.
Average maximum summer temperatures are in the mid to high 60s with a minimum average in the mid 40s. Because of the elevation and distance from the moderating oceans, winter temperatures are much colder than those in in the Seattle area, with minimum temperatures in the 20s and maximum temperatures in the 30s.
Lake Easton is located in Kittitas County on I-90, 16 miles east of the Snoqualmie Pass summit. It is one mile west of the town of Easton and 15 miles west of the town of Cle Elum.
