I’d give more stars if I could. I’ve been coming to Colonial Mast Campground for years, and it truly feels like a second home. The warmth of the people, the peacefulness of the lake, and the spotless grounds make every visit special. And when you hear the call of the loons on a still summer morning, you’ll understand why this place captures your heart.

We stayed at colonial mast for 4 nights this October. Great campground right on the lake. Awesome heated pool and hot tub. We rented a canoe and went for a paddle on the lake. Really nice.. we will def be back!

You can stay right by the lake and get a boat dock for the stay . Very well run, clean and friendly campground. Mostly seasonal but if you stay for few days or weeks you have the best spot and the view of the lake .

I think I’m a bit of a snob. I looked at this place as a convenient, affordable place to do my physical therapy after a double knee replacement . It’s 20 minutes from my home on Sebago Lake. My other option was the pristine pool at St. Joseph’s college in Standish, a beautiful campus with all the positive energy that a college campus offers . I found myself retreating to Colonial Mast more and more . The pool temp is warmer, the campground atmosphere was welcoming , hours much more flexible. In those “down days” where you need an extra push to get out to PT I found the unassuming atmosphere to be welcoming and relaxing. Sometimes we need to treat ourselves gently . This is a good place for that .

Just stayed here for the first time while celebrating our 50th anniversary. We found the staff to be super friendly, and the locals were so great, too! Restrooms were spotless and tastefully decorated with bear, tree, moose amd loon themes. The grounds are impeccably maintained, and we loved that quiet time was enforced. The water aerobics class Thursday night was wonderful after driving all day! Thank you everyone for an awesome weekend! We will come again!

We booked a pool party for my daughter's 6th birthday... place was clean, and great atmosphere, although a bit hot... our party was piggy backed on another party, so I was unable to set up while the kids were swimming, as the other party was in the lodge... and then I was having to decorate and set up as the kids all were just sitting and waiting and then our second hour felt very rushed to do everything because I spent 15 mins of it setting stuff up, and then to get through food, cake, and gifts, we didn't have time to do the other activity we had planned... so that was alittle unfortunate, but knowing that all now I would plan more accordingly for future parties if we did it again... I loved that they had life vest, toys, noodles, and goggles for us to use while there! Sarah was the staff member on site and she was very nice, and attentive.

I love that the pool water is warmish to go swimming. Plus when they have the hot tub available that is really nice and clean. Their showers are also great love how I can take a hot shower and sit and clean if I wanted to. There is no downs about the indoor pool place.
