This was our first camping trip of the year and we loved being right on the beach. There are no hookups but water is easily acquired and there is a dumping station. We loved being able to hike for hours right from our campsite. While the beach in the campground is very rocky it is a short walk to beautiful public beaches. I cant wait to return to this campsite.
Being a state park on the beach, there is little in the way of foliage so there is nothing between you and the next camp site to give you much privacy. But aside from that, you are anywhere from 5 seconds to a 1 minute walk away from the beach. The smell of salty ocean air, and the sounds of the waves are a great way to relax. The area is very dark at night so if you are into stargazing, this is a great place to bring a telescope or a good camera to take some pictures. We woke in the middle of the morning to see the Milky Way in the sky above us quite clearly.
The bathrooms are good, and while not the most modern looking, were clean. We stayed in early June and found both nights to be very cold with the constant wind coming off of the water so bring an extra blanket.
The best!! Our site was perfect for tent camping and pets!
We go to Horseneck for a weekend each year. If you book early enough you can get a site along the beach. Either way you can hear the waves from all of the sites at night and they're all a short walk to the beach. The beach is a bit rocky but the water is blean and sandy. The sites are spacious, yet if you pick one in the midde of the grounds you're pretty much out in the open. Each site comes with a picnic bench and a fire pit with a grate. You can buy bundles of wood at the ranger station for 5$ each so make sure you bring cash. The bathroom facilities are clean and there's a decent dishwashing station. There is a lot to do in the area too. I recommend the MA Audubon park, Buzzards Bay Brewing, and Westport Rivers Vineyard.
Horseneck Beach campground sites aren't particularly large, and are setup more for car camping and RVs than for tenting, but the site has great showers and a modern shower facility, and being able to walk out to the beach through the barrier dune to watch the sunset and sunrise is absolutely fantastic. I've camped here twice, once with a small group of 4 on one site, plenty big enough for all of us to have a tent, and once with a group of 15. Easy access to running water from most sites and pretty good, free, showers given the campground layout. Only downside is that the online reservation system requires a 2 night minimum, but calling the campground attendant can sometimes result in a one night reservation, especially early in the season when they're holding sites for last minute arrivals.
Hard to beat being less than an hour from Providence, RI and camping adjacent to a beach.
