Check a Maryland campground
Pick a campground and your date. You'll get the day and time it becomes bookable, and a calendar reminder.
Campground guides: Assateague State Park, Assateague Island National Seashore (NPS campgrounds). More Maryland campgrounds follow the same rule; the tool on the home page covers them as we add them.
Get the reminder by email
One email before the big Mid-Atlantic release mornings (summer weekends at Watkins Glen, Assateague and Cape Henlopen), and when an agency changes its rules. Nothing else.
Before any reminder, you'll get one email asking you to confirm. Unsubscribe anytime. See the privacy policy.
