Tualatin Hills Nature Park - Beaverton, Oregon

This place is conveniently close to SeaSweets, our favorite Poke place. We grabbed lunch to go, finished it in the parking lot, and then walked for several miles on the nice paths. Most of them are fairly smooth but the wooden bridges are another story. It's still definitely worth the trip over and over again. The Visitors Center happened to be closed this time but we have seen it before.
