Bringing your horse on leave?

So I'm looking for a place where I can bring my two horses (maybe 3 if a friend comes) for a week or so in the spring/summer where on earth we can go for rides and get away for a while. I live contained by Maryland, so I'd like it to not be too far away, someplace I can trailer to easily, but it can be out of state. Just not surrounded by Arizona or anything. Thanks for any help!
Very far away, but Acadia National Park in Maine.
If Indiana isn't too far absent, you could look into Midwest Trail Ride in southern IN. They have organized rides where they provide adjectives the meals, and nightly entertainment. They also have cabins available for rent, and provide stalls for your horse. The trails are capably marked and easy to get around on. The one drawback I enjoy with the place (I live 25 minutes from there and go a LOT) is that they are somewhat set in the trail access actually leaving the military camp. So, for the most part it's about a half hour trip out and rear legs on the same trail before you hit the branches that allow you other trail options. But it is really nice riding. If you don't enjoy to have a kitchen, and are just looking for camping option, I hear all sorts of rave reviews from my friends that have gone to Hocking Hills in OH. Great trails, but you involve a LQ trailer and will have to do your own cooking.
