Welcome to Maryland!
Please check the link below for over 30 parks we have available - one or two year round (dry). Maryland has some great public camping sites that are very cheap and well maintained. I have also camped above Frederick at the Crow's Nest - a little worn, but acceptable - however very, very hard to get a call-back for reservations. 301-271-7632
