Tips from locals
My favorite hike. Easy access. 8 mile round trip. 4000 ft elevation gain. Views of all of Western Washington. $5 to park.
Great full day hike option at 8.0 miles, roundtrip. This can get busy on weekends, so we recommend going during the week if possible.
Healthy hike, gorgeous views, worth the effort. Very popular so head out early to avoid crowds.
