Olallie State Park is known for the scenic beauty of its two waterfalls. Located on the western slopes of the Cascade Mountains, this day-use park features 6 miles of hiking trail for visitors to explore the 2,500 acres of cliff formations and old-growth forest, teeming with huckleberries. An 80-foot bridge connects the park’s two main attractions: the Weeks Falls, at 77 feet high, and the spectacular Twin Falls, at 135 feet high. The winter is the best time of year to view the grandeur of these mighty cascading waterfallsWant to support Washington State Parks? Get involved by joining a friends' group.
