Take a ride on the Coulee Corridor Scenic Byway, an amazing 150-mile road trip revealing the story of the Ice Age floods when vast reservoirs of water flooded and receded from this valley hundreds of times. One of the most unique natural landscapes in the United States, this area was formed as the force of water fought against the strength of basalt rock. The result is a geologist’s mecca. Experience the ineffable in the landscape as well as world-class recreational opportunities. The Coulee Corridor is the second-most-important birding corridor in the United States. The byway offers recreation for everyone. Between three state parks, a national wildlife refuge, visits to the Grand Coulee Dam and Lake Roosevelt National Recreation Area, or Othello’s Sand Hill Crane festival, you'll find something for the whole family. Traveler services are clustered within the nine towns along the byway, leaving vast vistas wide open. A National Natural Landmark and a National Historic District, the Coulee Corridor is often selected for car commercials. Consistent grassroots support from every town along the byway and strong partnerships with both the Colville Indian Nation and Washington State Parks have enabled this byway to develop to a high level of maturity. Spend the day roaming the majestic Washington landscape on the Coulee Corridor Scenic Byway.
