We arrived at our hike-in site just after midnight and was pleasantly surprised that we were one of two groups of campers on that Thursday night. Firstly, the walk to hike in is gloriously short for car camping. We were able to schlep all of our gear in three trips. We had considered taking a wagon but I'm glad we didn't. The check in process the following day was very short, but be forewarned that if you leave the campground and return prior to getting your camping tag you may have to pay the park entrance fee (we did not but were warned).
There is sand everywhere (you are almost at the beach) so a small dustpan and brush will keep your tent tidy. The bathroom and showers are just outside the hike in parking lot, but could use an upgrade. The shower stalls don't have a private changing area, just a long bench on the opposite wall from the row of push-button showers. Also, the drain for the shower isn't in each stall so water tends to flood the area between the bench and the showers; bring a pair of shower shoes.  The water pressure was good and the shower was hot.  It may be a bit too much for little kids, though.  As the campground is usually fully booked, it would be nice to not have to leave my clothes and glasses on a public bench while I shower (I've had my Rx glasses stolen from a campground bathroom before). This is my only reason for the 4 star review. At night, we were able to hear the waves crashing on the beach, but have no ocean views. It was very soothing and I slept like a log! The camp store has wood for purchase, and scavenging dead wood wasn't a very successful for us outside of kindling.
There are plenty of walking and biking trails, a free nature center with a touch tank (tank closed on our visit due to Covid), and historic Fort Miles.
We would definitely stay again.
