The Old Mill RV Park feels much more like a trailer park than a costal campground, but they do allow tent camping. I wouldn't recommend it as a destination place to camp, but if everything at the coast is totally full this one will do in a pinch. It's perfectly fine for sleeping.

We used Old Mill as a jumping off point for Cape Lookout (because their campground was totally full) -- it's a 20 minute-ish drive away through rural farm land and gorgeous coast. It's also convenient for fishing and clamming in the Tilamook bay if you're bringing your own boat.

The Old Mill is right off of the 101 in Girabaldi--super convenient to the little downtown. The bathrooms are really far away from most sites. We drove when we went there.

There aren't exactly "sites" more of a really big field with picnic tables and markings. This did come in handy since we my friends had a boat trailer, and we were able to also park that in our "site".
