Olallie State Park

This day-use park is known for the scenic beauty of its two waterfalls – the 77-foot Weeks Falls and the 135-foot Twin Falls. It has six miles of hiking trails, cliff formations and old-growth forest. Winter is the best time of year to view the mighty cascading waterfalls.

In addition, the park contains the Olallie Trail, a challenging 9.2-mile mountain biking trail also available for hiking and equestrian use that provides several sweeping views of the Snoqualmie Valley and surrounding mountains. Completed in 2017, the trail resulted from a collaborative partnership among Washington State Parks, Washington Department of Natural Resources, the US Forest Service, the City of Seattle Cedar River Watershed, the Evergreen Mountain Bike Alliance, and the Mountains to Sound Greenway Trust. Greenway staff constructed approximately 4.3 miles of the eastern portion of the trail.
