If you're a birder or looking for a flat, easy walk, that can be done by anyone, then this place is worth a visit. If you're interested in the history of the area then you'll also enjoy a visit here. If you're local to the area and can get here in a little amount of time then you should visit as well.
A friend and I were looking for something chill to do today and, since I've been out in the woods and mountains a lot lately, this seemed like it would be a nice change of pace. We had good weather, albeit not sunny, and saw lots of birds, up to and including a couple of bald eagles in the distance. The trails were either wide, gravel roads, or well-maintained board walks. Due to COVID-19 there weren't any facilities open, so I don't know what might be on offer in that respect. Speaking of COVID, appropriate safety protocols were being followed by most, though not all visitors. Fortunately, when you come upon one of those groups who think masks and social distancing are infringements on their rights, you can easily move off to another spot while giving them withering looks they won't understand.
All in all I enjoyed my few hours here, but living north of Seattle and not being a birder I doubt I'll be back.
WTA is an organization that is powered by members, and if you're reading this trip report then I know that you value the resources they provide. So if you value what you get from WTA I hope that you're a member already, and if you're not then I really encourage you to become one! It's fast, it's easy, and the return on your investment is priceless.
