Summer: 6:30 a.m. to dusk.

Significant History

"Olallie" is the Chinook Jargon word for "berry." The park is rich in huckleberries.

Major Landmarks

The area abounds in huckleberries. The glory of giant old-growth trees vie with the grandeur of two waterfalls. An 80-foot bridge connects Twin Falls and Weeks Falls, located one mile into the park. The falls are particularly spectacular in winter when the water volume dramatically increases.

Interpretive Oportunities

An interpretive trail at Weeks Falls educates visitors on the history of an old wagon trail that once went through the middle of the park.

The rock-climbing area is adjacent to the park, above the Iron HorseTrail. Rock-climbing equipment is necessary. Fatal accidents have occurred when amateurs have climbed without proper equipment.

Olallie provides access to the Iron Horse Trail, an old Milwaukee Railroad path that starts in North Bend and extends to the Idaho border. The Iron Horse Trail permits mountain biking and horseback riding.

The river is open for fishing. Check local regulations.

The park offers a total of 11 unsheltered picnic tables in two picnic areas near the river and play field. All are available first-come, first-served.
