Twin Falls, Waterfall in Olallie State Park, Washington, United States.
Twin Falls is a waterfall in Olallie State Park that descends in multiple stages along the South Fork Snoqualmie River. The water flows over different cascades before gathering in a natural basin.
The waterfall was modified for hydroelectric production, which affects water flow during dry months. These interventions help maintain natural currents in winter and spring.
The Snoqualmie River and its waterfalls hold deep significance for Native American tribes who lived along these waters for generations.
The hiking trail is demanding and crosses a bridge with multiple viewing platforms along the river valley. Good footwear and attention to the path are necessary, especially in wet conditions.
The waterfall system features an unusual arrangement with a large water basin that forms after the first cascade segment. This natural basin creates a calm spot amid the flowing waters.
