The park is awesome, although the trip into the park can be unnerving by passing underneath high voltage lines. It was drizzling (big surprise) at the time, and the sizzle/crackling noise of the power lines just did not sit right with me. I made it across the power lines post haste. Oh, there's a beautiful view of the valley, but the picture is not posted, well because, I did not take it for one. And two, the power lines were in the way.
Anyways, past the power lines you go through a now nicely manicured trail, with excellent switch backs and check steps. Thanks Washington Trails Association (WTA)! I did not go see the rest of the sights, but there are big waterfalls at the end. Ergo, the name, Wallace Falls State Park.
Other than that it was a pleasant walk in the park.
