My husband and I had our first camping experiece together (in a tent) on our own the first weekend in May and we went to Greenbrier State Park. We had camped here a few years ago with friends who had a hard-wall camper, and I finally convinced my husband to give tent-camping a try, since we had many of the supplies for camping given to us from my parents. The Maryland State Parks we have been to are all wonderful. Greenbrier is very clean! We used their online map to look at the location of the camp sites, and could read the information about each individual site and see pictures too. I knew from my camping experience, that we would prefer a site on an outer circle (less foot traffic from other campers on their way to the bath house or water pumps) and one that didn't sit too close to another site. Their map is very accurate for the spacing of the sites, and we were very happy with the site we selected, based on their website information.
They also have a great public beach access area. There are tons of picnic tables and a very large swimming area. We look forward to returning here again.
