Maine caps camping at any one state park at 14 nights, and the rule attaches a season to that number. Rule 13 of the Bureau of Parks and Lands regulations reads: “Camping, at any one park, shall be limited to a cumulative total of fourteen (14) nights from the last Saturday in June through the third Saturday in August.” Read September 24, 2026. The rules are made under Title 12, section 1803, subsection 6 of the Maine Revised Statutes.
So the cap is not an annual total and it is not a rolling window. It is a summer rule, and right now it is outside its own dates.
What that does not mean
It does not mean you can settle in. The rules page states no other night cap, and a rule that says nothing is not a rule that says yes. We have not verified any off-season limit, and whether a park manager applies one is not something the page answers. Ask the park.
The practical limit this time of year is simpler anyway: the campgrounds close. The Bureau’s off-season page says off-season camping runs from the end of the summer camping season to noon on October 15 at select locations, at standard camping fees, and then gives per-park dates for 2026.
Warren Island closed at noon on September 15. Mount Blue’s campground and day-use area close at noon on Friday, September 25, 2026. Peaks-Kenny and Rangeley Lake close at noon on October 3. Aroostook, Bradbury Mountain, Camden Hills, Cobscook Bay, Lake St. George, Lily Bay and Sebago Lake close at noon on October 15. Read September 24, 2026.
One honest note on Mount Blue. The sentence after its closing date runs off mid-thought on the Bureau’s page, so we cannot tell you what it was going to say about off-season or winter camping there. Call the park at the number on that page rather than reading the fragment the way you would prefer.
Winter camping is a separate season with a separate limit. Select parks take primitive tent campers from December 15 to March 15: no water, no amenities, no cleared sites or trails, designated sites only, and a 7-day limit of stay. Fees are cash or check at on-site self registration, with the $50 registration fee waived.
The other Maine system
Maine runs two public camping systems and they do not share rules. The state parks are the one above. The Public Reserved Lands, the backcountry blocks the Bureau also manages, carry their own stay limit and mostly first-come sites. We cover that side on our Maine free camping page. Do not carry a number from one system into the other.
While you are in the park rules, three more are worth knowing. One motor home, trailer, camper van or slide-in camper per campsite, and not more than two motor vehicles. Quiet hours run 10 p.m. to 7 a.m. Generators may be used between 8 a.m. and 8 p.m.
Whatever this page says, the posted rules at the park and the park manager on the ground decide what happens to you. Call before a long drive in the shoulder season, because a closing time of noon is a real deadline.
