My family stayed here for a night when we went out to Washington a few months ago. It was a nice little place. Mostly we stayed here because of how close it was to seattle, so we were't at the campground very much. It does have a pretty good amount of sites. It's got showers and bathrooms which is always nice at a campground. It does have a lot of activities because of how close it is to the water. We saw people fishing, diving, sailing, etc. The only thing I didn't like about it was that building wood fires isn't allowed in the campground. 

The seattle area has all kinds of things to do. My family went to Pike Place Market which was awesome to see. We saw a Mariners game, the space needle, and went on some awesome hikes around the area. 

Overall the campground was a pretty nice place to stay, especially if you are trying to visit the seattle area for a couple of nights. Great place!
