About Twin Falls
Twin Falls offers a refreshing escape nestled within Washington’s lush Olallie State Park. This primitive cold spring features striking waterfalls cascading into the Snoqualmie River, creating inviting swimming holes surrounded by towering old-growth trees. The natural setting combines the thrill of jumping off rocks with the serene beauty of the forest landscape.
Getting There
Reaching Twin Falls requires a moderate hike of about 25 minutes from a limited parking area inside Olallie State Park. The trail weaves through dense ancient trees, with sights and sounds of cascading waterfalls encouraging you onward. Parking spots fill quickly in summer, so plan to arrive early to secure a place.
What to Expect
The water here is cool and crisp, perfect for hot Washington days, but strong currents demand caution—enter only when flows are gentle, typically in late summer. The atmosphere is peaceful yet lively with fellow visitors drawn to this natural swimming hole and jumping spots. Facilities are minimal, preserving the primitive character of the site.
Tips for Visitors
Visit later in summer when the river currents calm down for safer swimming. Bring sturdy shoes for the trail and be prepared for limited parking and a small state park fee. Always respect warning signs about currents and never swim if the water feels swift. Pack out all trash to keep this pristine environment intact.
