A modest seasonal waterfall that cascades over moss-covered rock in Cougar Mountain Regional Wildland Park near Issaquah. It flows best in the wet season and is a short forested hike from the trailhead.
Its 28 ft drop is taller than about 17% of the 775 waterfalls we track.
Coal Creek Falls sits on Coal Creek. It lies in King, Washington. The site is on public land managed by King County Parks (Cougar Mountain Regional Wildland Park).
This is a short hike waterfall: reached by a short trail, generally under about a mile each way. The walk in is brief — comfortable shoes are usually all you need. The walk to the main viewpoint runs about 2.2 miles round trip. The nearest town is Newcastle.
When to go: winter. Flow usually peaks after snowmelt and heavy rain and tapers through late summer — a quick look at recent streamflow and the managing agency's conditions page can save a wasted trip.
