Unlike most of our state’s rivers, the Pend Oreille flows almost straight north between Newport, Washington, and the Canadian border. Several hydroelectric dams cross the steep canyon in northeastern Washington, including Boundary Dam near the border. In 2023, the U.S. Forest Service and Seattle City Light opened two new overlook areas designed to meet Forest Service accessibility guidelines: Riverside Canyon and Peewee Falls. Construction of the overlooks fulfilled one of the requirements under Seattle City Light’s license to operate Boundary Dam. Seattle City Light funds also paid for an upgrade to the nearby Boundary Dam overlook.
The trail from the parking area descends through a few switchbacks, leading to a viewing platform with benches where you can relax and enjoy the view of Peewee Falls and Hooknose Mountain across the valley.
After you leave the Peewee Falls overlook, turn left on Eastside Access Road and visit Vista House, where you’ll get a clear view of Boundary Dam. A short trail descends from Vista House to an overlook platform.
A 9-mile hiking trail connecting the Peewee Falls and Riverside Canyon Overlooks, also funded by Seattle City Light, is nearly complete as of 2025.
