Catoctin Mountain Park Campground is a 5.3 mile out and back trail located near Sabillasville, Maryland. The trail is rated as moderate and primarily used for hiking and camping.
This campground was a bit of a drive but worth it! They don't take reservations, it's based on first-come first-serve. You drive through the mountains, up beautiful hills, the scene is just breath-taking. When you get to the campsite there is a little box at the entrance. You drive around the loops and when you find an open site you go to that box and use one of the envelopes to mark where you are staying. It's $20 a night, not too bad, and there is no minimum of nights you must stay. You can't bring your own firewood (due to foreign bugs being bad for nature there) but they have a deal of a full bucket of wood for $5 or you can just find your own in the campground. The hosts were very nice and there is a bathroom facility with showers. There are also hiking trails throughout the campground. I highly recommend this, it's fun, relaxing, and gorgeous!
