Like most of the reviews, the campsites are roomy but little privacy. The bathrooms are clean and showers are nice for people who aren't big into camping. 

There are lots of old redwood stumps to explore and climb on for kids. The Gould nature hike is easy and informative with lots of interesting sites. Walk down to the river for stone skipping, wading fun. Also the river hike on the opposite side of the river was amazing, we didn't run into another hiker, so peaceful. 

Also the rangers there were awesome.  Our car wouldn't start when leaving (due to leaving car doors open).  But the rangers had a battery starter pack. Saved us hours of waiting for AAA.
