Grand Coulee Trip Planner

Welcome to Grand Coulee!

The Grand Coulee area can be found on the Columbia River Valley Plateau of Washington. One of the major draws for visitors to this area is the Grand Coulee Dam, the largest concrete dam in North America. Completed in 1942, this dam provides irrigation, hydropower and flood control for valley residents, and also offers a laser light show that is projected across the dam front nightly throughout the summer. Moses Lake is the largest city in the area, providing visitors with accommodations and services, as well as a number of recreational activities ranging from water sports to picnicking. Washington State's pioneer heritage and Native American history in the Grand Coulee area are well documented at attractions such as the Colville Tribal Museum, which is located in Coulee Dam. An exciting and enriching historical visit awaits travelers to this part of Washington.
