Seawall Campground in Maine. Ringed marker is this site; the other dots are the 6 public campsites we map in Maine.
For Seawall campsites, 90 percent of campsites are released six months in advance on the first of each month at 10 am EST. The remaining 10 percent are released at 10 am 14 days ahead of a desired arrival date on a rolling basis. For example, if you plan to arrive on May 24, you can make an online reservation starting at 10 am EST Dec 1 from the first release or starting at 10 am EST on May 10 from the second release. All campsite reservations must be made through recreation.gov.
