The Coulee Corridor National Scenic Byway is a destination with infinite indoor and outdoor opportunities. Coming soon will be installation of five community kiosks in the towns of Grand Coulee, Coulee City, Soap Lake, Warden and Othello.

To date as of September 2019, the kiosk project has made great strides forward. Standardized content has been approved by the Coulee Corridor Consortium for each site and each city has written and approved the content of their specific locality.  In addition, the basalt foundations at each site have been placed and are anchored in cement.  All that is waiting for are the construction and installation of panels to complete each display.

Trips along the Coulee Corridor National Scenic Byway can provide memorable experiences for travelers who visit or view sights and places between Omak and Othello along SR 17, SR 155 and US 2, and follow spur and loop routes in Adams, Douglas, Franklin, Grant, Lincoln and Okanogan Counties.

Among its unique features, the Coulee Corridor illustrates the dramatic effects of ancient catastrophic Ice Age floods which left behind majestic and beautiful coulees. Among the sights are deep gouges in the underlying basalt bedrock made by ancient post glacial floods, gigantic gravel bars, and the effects of glaciation in this part of Eastern Washington.

Grand Coulee Dam is the keystone of the Columbia Basin Irrigation Project and provides the water source for over 75 types of farm crops. Discover fantastic recreation opportunities including boating, birding, fishing, and swimming on Lake Roosevelt, Banks Lake, Potholes Reservoir, on the Columbia National Wildlife Refuge and many other lakes along the byway. Enjoy the Laser Light Show on the face of the Grand Coulee Dam every night from Memorial Day weekend through September.

Journey through the Colville Indian Reservation which is steeped with history, the culture of the Colville Confederated Tribes, renowned artists, the Tribal Museum in Coulee Dam, and exhibits the native resting places of Chief Joseph and Chief Moses in Nespelem.

Check out the origin of Soap Lake and its unique physical and chemical properties. Soap Lake mud, its salty water, sandy beaches and the warm weather are some of the reasons  people come here.  Ever wonder why there are so few fisherman on the lake?  In the last few years, an annual Pow Wow has been reintroduced and there are years when hydroplane races are allowed.

Ephrata is the Grant County seat and home to the courthouse which finished construction in 1918.  There are many other historic buildings in town and near or in many of the adjoining towns throughout the Coulee Corridor. For example, there is St. Mary's Mission near Omak established in 1886, Hartline School, now abandoned built in 1922,  Almira State Bank and Wilson Creek's Citizen Bank, built in 1902 and 1901 respectively,  the Old Hotel in Othello built in 1912, and colorful historic time period murals in Connell,  Warden, and Moses Lake to name a few.

Farming and ranching are the mainstays of the agricultural economy. With the introduction of irrigation water from Grand Coulee Dam in the early 1950s, the desert of the Columbia Basin was turned into an oasis. Much of the area receives less than 9 inches of annual rainfall though with irrigation, crops that can be grown are almost limitless.  Grant County is the highest potato growing county in the nation. Besides row crop production, there are orchards, vineyards, dairies, and livestock.
