We stayed at site 136 in dogwood canyon, and it was lovely. Next time I'd stay at 137 for a bit more isolation, as you could see the boardwalk from our campsite as the area is sparsely wooded. Couldn't see the parking lot due to brush, but it was a very short walk and that was nice. Composting toilets are the only ones available in the area(even at the parking lot) and you have to walk/drive to the electric sites for showers or flush toilets. You could see the toilet in our area from the campsite, but did have to walk around a bushy area to get to it but it was doable in the middle of the night. There is a firewood vending machine there that's very cool and is reasonably priced for good wood.
Don't drive five hours like we did for this campsite, but it was nice. We had a quiet section even during spring break, and if you're a fisherman there's easy access to a couple of coves that look like they would be great fishing spots.
