We visited during the week and it was pretty empty.  Sites are spacious though they are grouped in such a way that 2-3 sites are open to each other.  Would make for a great place for groups with multiple tents.  All sites except two have river or stream access.  Getting to the water from the remaining sites, one of which is very private and the other very public, is difficult.  

There is some hiking nearby including a short hike to some beautiful waterfalls.  Dosewalips State Park is close by for some ocean and river fun.  There is also a large grassy area to play.  We saw an elk.  Beach not great.  Seal Rock is also very close and you are allowed to harvest oysters without a permit.  The beach area is quite pleasant and, surprisingly, the Sound is warm making for decent water play.
