Grant County · Eastern Washington
Moses Lake
Twenty-five miles of freshwater shoreline, sand dunes stretching more than 3,000 acres, and over 300 sunny days a year make Moses Lake an inland summer playground most of Washington has never discovered.
Moses Lake sits at the center of Washington’s Columbia Basin, where midcentury irrigation transformed high desert scrubland into one of the most productive agricultural regions in the country. The city grew alongside that transformation, and the lake itself now covers nearly 6,200 acres with 25 miles of shoreline threading through town.
What surprises most visitors is the recreational variety. The same landscape that grows more potatoes per acre than almost anywhere in the world also produces some of the Northwest’s most accessible sand dunes, reliable summer sunshine, and a freshwater playground that runs from May through October. Families come for Surf n Slide Water Park, anglers for largemouth bass and walleye, and off road enthusiasts for the massive dune system near Connelly Park.
Moses Lake serves as the commercial center for Grant County, which means there are real restaurants, quality hotels on the water, and services that make a proper stay comfortable. For decades this has been a gas stop on I-90 between Seattle and Spokane. Stop for a night and the lake, the dunes, and the unhurried Eastern Washington pace make a genuine case for staying longer.
Getting Here
Moses Lake sits 180 miles east of Seattle on Interstate 90, about a 2.5 hour drive depending on Snoqualmie Pass conditions. From Spokane the drive is about 90 miles west on I-90, roughly 1.5 hours. No passenger rail serves Moses Lake, so a car is the standard option. An alternative westbound approach from Central Washington runs east on US 2 through Wenatchee and south on SR 28, adding scenic variety through the Wenatchee Valley.

Planning Your Visit
Summer is peak season, running late June through August when the lake, water park, and sand dunes operate at full capacity. May and September offer warm days with noticeably fewer crowds. Winters are cold and dry with little snowfall in the city itself. Budget at least two nights to take in the lake, the dunes, and a day trip. With over 300 sunny days a year, bring sunscreen: the reflection off the water amplifies the exposure significantly.
