Great car camping for young families
We come here often as we live in Olympia.
Pros: close to the city in case you forget something or a little one has a meltdown, lots of varied activities: biking, light mtb, trail running, hiking, paddling & fishing ( there's a small lake).
Cons: can get crowded and the campsites are pushed up pretty close together so you'll likely get to know your neighbor.
