Tips from the Community
The Hall Creek Trestle is a historic steel and timber railway bridge built in 1912. It was once the old Milwaukee Road until, in 1988, a storm washed away a central 171-foot section of the bridge. In the 1990s, Washington State Parks restored the trestle, reconnecting the east and west segments of the former rail line, which is now part of the Palouse to Cascades (Iron Horse) Trail. The views down into Hall Creek Valley are genuinely stunning and worth the ride!

Great views from here. And... the middle of the trestle is different than either end because it had collapsed and was rebuilt in the late 90's

I am always amazed how different this lake looks in the spring (full) versus the fall (almost empty). Those "Seals" are visible in the fall but then go for a long swim in the winter and spring...

The State Park is on the West shore of Lake Easton - very nice campground. An excellent overnight spot in the Spring/Summer/Fall when doing the Palouse to Cascades trail. Worth looping around the lake to see it from all sides and experience the tunnel and bridges. Decent provisions available in town.

Great bridge! You can ride all the way around Lake Easton, over this bridge, under a cool tunnel, past the State Park, and across another bridge that used to be the main highway across the cascades (Highway 10). Very beautiful ride!

This is the last tunnel you will see until (or the first tunnel you have seen since) Thorp. Wooded, along the lake, nice spot to stop.

...and for no particular reason, someone has thought of your needs. This toilet is here, just in case!
