Sebago Lake and Lily Bay open three days before every other Maine state park. For 2027 that's Monday, February 1 at 9 a.m., when the whole season opens at once. Bookings made in February need a 4-night minimum here, and pets aren't allowed.
The booking rule here is Maine's: see Maine booking rules.
