We stayed in the C Loop, walk-in camping, for one night in July. The C loop is great! More secluded than most state park tent camping areas. Water by the parking lot. The bathrooms are a bit of a hike away. I'd stay here more often but with the Gorge 400 trail closed due to the Eagle Creek fire and many nearby sites closed due to COVID, it isn't the best jumping off point for Gorge adventures. I still plan to come back.

It looks like site 1 and 5 in the C loop are the least secluded, but they all still have much more privacy than a normal state park site.
