First visit here on Labor Day weekend. Most campsites were occupied, but spread out pretty well. Pit toilets, water pump, garbage & recyclable dumpsters; but no showers. Firewood shack was open 24/7 with $5 per bundle. We had very few bugs during our stay.
Highlight is kayaking on the east fork and Lake Arbutus. Not all campsites on the river side have kayak-friendly access, but a good ramp is by the park entrance. We drove kayaks up to the East Fork Road bridge, and paddled downstream to the campground. Some rocky sections; with end-of-summer water levels we got hung up on rocks a couple times, but didn't have to get out of the kayaks.
One nature trail from the campground goes a mile along the river and accesses some fishing spots. The state forest major hiking trail areas are a good drive away, but are excellent.
