This review is pretty belated, but we camped for 10 days last August with some friends. We had our PUP and they had a cavernous REI tent. The review is multi-faceted, but here goes: The grounds: The campground is AWESOME in many respects. It's very very clean, each site has power and water hookups, and the campground is surrounded by towering fir trees. The loops are large, but small enough that we always felt comfortable allowing the little kids to ride their bikes around as long as they were accompanied by an older kid. The bathrooms are clean and hot showers are FREE. I repeat: FREE! The sightseeing opportunities in and around the park are limitless. The ocean is amazing, the shipwreck is fun to visit, the bike trails seem limitless, Coffinbury Lake is nearby and a great alternative to the ocean beach when it's windy, and the WWI/WWII forts are tons of fun to explore. Save some money to get the guided underground tour. It's worth it and the kids loved it. The campsites: As I mentioned, each site has power and water and is significantly cheaper than a hookup site at WA State Parks that we typically visit as we're Washingtonians. There are a variety of different layouts at sites and with very very few exceptions, I really didn't see any that I thought were unsuitable for camping for several days. The downside is that if you're camping with friends in a tent, the sites are pathetically small for tents. Trailers were great, tents are not. Several people we saw had tents that were forced to be almost next to the road as the tent sites were so small. The far south loop (can't remember the letter for it) was the only exception to loops I didn't like. It was much more wide-open and had significantly less privacy than others. I like a bit of privacy in camp sites, and found there was nearly none in that south loop. We'd go back, but only if we were with friends in a trailer as well. Otherwise, it's just too much of a gamble.
