Trails for everyone, forever

Home Go Hiking Hiking Guide Lewis and Clark Trail State Park

WTA is a nonprofit that needs you

We’re just as excited as you to get the summer hiking season started. We're psyched our website and work for trails help you get outside.

But we're a nonprofit run on donations from regular people. If everyone who visited this website this holiday weekend donated $9/month, it would fully fund our work for the next 2 years. Of course, time spent outdoors is priceless, but every donation large or small helps us support those experiences for everyone.

Please take 2 minutes to chip in $9.

Walk down the road into the campground loop and take a right onto the grassy (or muddy in the springtime) trail.
Enjoy the singing birds as you ramble through this luxurious oasis in the dry eastern grasslands.

The trail takes you along the banks of the Touchet River with farmland views and opportunities to soak one’s feet on a hot day.

Make your way through a mixture of cottonwoods and ponderosa pine that are overgrown with rich vegetation, and ponder Lewis and Clark’s thoughts upon passing through in 1806, on their return from successfully crossing what would become the rest of America. 

This quick hike leaves you plenty of time to enjoy the excellent trout fishing and river tubing.

WTA Pro Tip: Visit a local winery 0.6 mile east of the State Park on Highway 12, in the historic Dumas station apple packing shed.
