Maps & Location

Mazama is located on Highway 20, which is 14 miles west of Winthrop, WA. During the summer months, it is usually accessible by all highways from Western Washington, Oregon and British Columbia. Please note that during winter months, the Washington Pass portion of the highway is closed. Visitors are strongly urged to check pass conditions during all times of the year at wsdot.wa.gov. As the location is in the mountains, road conditions can change quickly, even in the sunny summer months. Travelers are discouraged from relying solely on car-based GPS or other mobile navigation directions.
