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.
