Questions
When do Maine state park camping reservations open for 2027?
Sebago Lake and Lily Bay open Monday, February 1, 2027 at 9 a.m. Eastern. Every other Maine state park opens Thursday, February 4, 2027 at 9 a.m. Each opening moves one day if state government closes for a storm. The whole season opens at once.
How far ahead can you book a Massachusetts state campground?
Up to 4 months before your arrival date, one day at a time, after DCR opens the system for the season. In 2026 the season opened February 18 at 9 a.m.; the 2027 date isn't announced yet.
When do Cadillac Mountain reservations come out?
30% of each day's vehicle reservations are released 90 days ahead and 70% two days ahead, both at 10 a.m. Eastern, on Recreation.gov. Walking, biking or a taxi needs no reservation.
Can I book Rhode Island state campgrounds for 2027?
Not yet. Rhode Island has put all 2027 camping reservations on hold while it picks a new reservation provider, and no reopening date has been announced.
Is this an official reservation site?
No. This is an independent site, not affiliated with any state park agency or the National Park Service. It works out dates from each agency's published rules and links you to the official booking site.
