Hike to Twins Falls in Ollalie State Park


Renowned for its waterfalls, Olallie State Park is a perfect place to kick off the hiking season. Its moderate trails lead to the popular Twin Falls, Weeks Falls, and other cascading waterfalls. The trail also lead to the remains of a massive landslide to Cedar Butte.

Mountain bikers may ride the 20-mile-long Olallie Trail which climbs more than 3000 feet and provides stunning views of the Snoqualmie Valley. There are days of activities in four different cliff areas for mountain climbers. The routs have technical ratings of 5.5 to 5.13b

Hikers and cyclists can reach Palouse to Cascades Trail from the Cedar Fall trailhead. Rewarding fishing can be found on the South Fork of the Snoqualmie River.

This park is within 45 minutes of Seattle and lies on the Western Slope of the Cascade Mountains. The park has several trailheads and offers a landscape of powerful falls, forest, sweeping views, and a rushing river.

Park Features

Olallie State Park is a 2,329 acre park east of Seattle. It offers 6 miles of moderate hiking trails, fishing, cliffs, rock climbing opportunities, and access to the long distance Palouse to Cascades Park Trail.


In 1950, Washington purchased the 160 acre parcel that became Twin Falls State Park from Puget Sound Power and Light. The park expanded in 1976, and the in 1977, the name was changed to Olallie which is the Chinook word for salmonberry. There was an abundance of salmonberries in the area of the park. The Old Snoqualmie Wagon Road, completed in 1867, passes through the picnic area of the park. In 1905, the first automobile drove over the old wagon road and the Sunset Highway gradually replaced the old road afterwards.
