Frenchman Coulee Falls

Frenchman Coulee Falls, located just off Interstate-90 in Central Washington, is an ephemeral marvel of nature, flowing seasonally to reveal a breathtaking 200ft horsetail cascade. This waterfall dramatically spills over a red basalt ledge, with its largest free-falling drop towering over 100ft. The falls are best viewed in spring or after heavy rains. Surrounding the falls, an extensive trail system weaves through the cliffs, offering opportunities for rock climbing and exploration among the ancient geological formations.

The Drive

WTA’s July 21, 2026 notice reports the road to the Frenchman Coulee trailhead closed due to rockfall. Check current WDFW alerts and follow posted closures before planning access.

The Hike

The WTA notice cautions against using the entrance or the opposite road as parking alternatives. Confirm current access before hiking.

The Falls

In peak conditions, this slender cascade transforms into an imposing spectacle. However, for much of the year, the falls dwindle to but a gentle trickle.

Don’t Forget

Summer visitors should remain vigilant for rattlesnakes and the relentless sun, as the trail’s open exposure offers little respite.

Surrounding Area

Beyond the falls, Frenchman Coulee unfolds into a landscape rich with natural and cultural highlights. The Gorge Amphitheater, renowned for hosting some of the biggest names in music, sits as a crown jewel in this rugged terrain. Nearby, the Ancient Lakes area beckons hikers with its trail systems weaving through stark basalt cliffs to reveal hidden waterfalls and serene lakes, a testament to the Ice Age floods that shaped this land. This region of Central Washington, distinct from the lush alpine forests typically associated with the state, offers a dramatic backdrop for outdoor enthusiasts and geology aficionados alike.

Here, volcanic activity and ice age floods have carved a landscape adorned with columnar basalt formations. Nearby, Central Washington’s sand dunes, such as Beverly Dunes, welcome ATV and off-road enthusiasts, and the Hanford Reach National Monument offers trails leading to seemingly out-of-place sand dunes, enriching Washington’s diverse natural tapestry.
