Currently operated as the family-owned Colonial Mast Campground for 48 years, the property boasts more than 2,500 feet of pristine waterfront, expansive sandy beaches, and an extensive docking system with 72 boat slips. Licensed for 110 RV campsites, including some year-round sites, the property features an impressive collection of existing infrastructure, including an indoor pool facility, camp store with commercial kitchen, recreation hall, bathhouse, garages, and a waterfront owner's residence. Many of these structures are grandfathered within the shoreland zone, creating significant value and flexibility that would be difficult to replicate today. With over 7,000 feet of combined road frontage along Kansas Road, Bove Road, and Colonial Mast Road, this property offers exceptional access and development potential. Whether envisioned as a continued campground operation, a large-scale residential development, a luxury waterfront community, or an extraordinary private family compound, the possibilities are unmatched. Enjoy direct access to 11 miles of boating and recreation on Long Lake, with navigable access to Brandy Pond and Sebago Lake. Ideally located in the heart of Maine's Lakes Region, the property is just minutes from the Naples Causeway, 15 minutes to Pleasant Mountain Ski Resort, and only 45 minutes from Portland. Opportunities of this scale, with this amount of waterfront, acreage, infrastructure, and development potential, rarely come to market. Own one of the largest and most significant waterfront properties in the Lakes Region to hit the open market.
