Upper Oak Bay Park

Upper Oak Bay CG: A nice day use play park for kids. I vault toilet. No showers. One potable water spigot. Rest are for washing.

There is NO path down to the lagoon other than a precipitous dirt chute requiring a rope to climb back up. 

Nice view from a few frontal sites.

Lower Oak Bay CG is wide open, so better for RVs and Vans. Easy shoreline access for small boats.

Pro: My little one loves the playground and a green field. Beautiful view of the bay. Reasonable price. Con: No shower place. Hard to fill the fresh water tank.

The upper campground is nicer than the lower (basically a gravel lot for $20). The upper has a lot of trees to divide the non-electric sites nicely. Sites feel far apart but since it’s not super green, you can hear neighbors. There’s a vault toilet, trash and water spigot on-site. There’s a nice playground for the kids. It’s $20 for the non electric. Electric/water sites are available and are full sun along the water. Really nice area to walk the dog and very quiet at night.

Campsites are super close together, not much privacy. We easily overheard our neighbors conversations and cars were driving by campsite frequently in the evening. Also, the water is pretty much blocked by the RV sites. The ground was mostly rock so getting tent pegs in the ground was difficult.

I think this is the better of the two Oak Bay campgrounds (upper and lower). It has some nice sites in the woods with privacy. There are a couple of sites with good views, but they are very close to each other. 

I would recommend camping in one of the wooded sites, and then walking/driving to the Lower Campground for the day. That's a much more beautiful spot, but there are no trees and the sites are right next to each other with no privacy.

You're also very close to Marrowstone Island, which is one of the best kept secrets of the Olympic Peninsula.
