The Campground at a Glance
How to Reserve a Site
Book at CampWithME.com, the state's reservation site, or call the Campground Reservations Call Center: 800-332-1501 from a Maine (207) number, or (207) 624-9950 from out of state. The call center is open 9 a.m. to 4 p.m., Monday to Friday, from the first business day of February to the second Friday in September. The website stays open all the time.
Reservations are for camping parties of six or fewer, with at least one adult aged 18 or over. You must book by 4 p.m. at least one day before you arrive.
When Sebago Reservations Open
Sebago and Lily Bay open their season's bookings first. In 2026 that was Monday, February 2, at 9 a.m., three days before the other state park campgrounds opened on February 5. Group campsites and picnic shelters open by phone on the same first day.
The February Four-Night Rule
If you book a Sebago site during February, the Bureau requires a minimum stay of four nights. After February the usual minimums apply: two nights for any stay that includes a Friday and Saturday, and from July 1 onward a one-night stay is allowed at every park, weekends included.
How Long You Can Stay
From the last Saturday in June through the third Saturday in August, each person may camp a total of 14 nights at any one park. Outside that window there is no maximum stay.

No Pets in the Sebago Campground
Pets are allowed at every Maine state park campground except this one. The Bureau's rule is plain: no pets in the Sebago Lake State Park campground. If you travel with a dog, plan a day visit to the Casco side instead, where leashed dogs can use the trails and picnic sites. See dogs at the park.
What Each Site Has
Every site has a picnic table and a fireplace. Around the campground the Bureau's map shows hot showers, drinking water, restrooms, dishwashing stations, a playground, a trailer dumping station, trash and recycling, a nature center, an amphitheater, campground hosts, accessible sites, and two beaches for campers: Naples Beach and Witch Cove Beach. Sites are coded by size, from small sites for tents and pop-ups up to sites for campers longer than 35 feet. See the campground map guide.
Sites With Water and Electric
Sebago is one of six Maine state parks with water and electric hookups, alongside Aroostook, Camden Hills, Mount Blue, Peaks-Kenny and Rangeley Lake. Hookup sites cost $10 more a night. When you book online, enter your equipment size so the search shows only sites that fit.
After Mid-September
The reservation season closes in mid-September. In 2026, from Monday, September 14, every site became first-come, first-served. The Bureau says you can camp until October 15 at most parks but asks you to call to confirm closing dates.
Winter Camping
Winter camping is available at Sebago. It is not booked online: call the park at (207) 693-6231 to ask and to reserve.
