A once-in-a-lifetime opportunity to own Mason Lake's most iconic waterfront property. Spanning 47 acres with 3,200 feet of shoreline, this one-of-a-kind legacy estate offers the scale, privacy, and natural beauty that rarely become available. Fish-bearing Shumacher Creek winds through 12 acres of old-growth forest, crossing beneath a classic national park-style wooden vehicle bridge and separate pedestrian bridge before flowing into the lake. The waterfront is built for generations to enjoy, with a private boat launch, launch dock, five personal docks, a swim pier, and a sandy beach. Beyond the shoreline, the property features a large level play field, three picnic shelters, and a spacious beachfront picnic shelter with an attached kitchen, creating the perfect setting for gatherings with those you cherish the most, community events, celebrations, and outdoor recreation. An existing 85-site campground includes two residential structures, a small office building, multiple restroom buildings, and additional picnic shelters, providing immediate functionality while preserving exceptional future potential. Zoned RR-5 (Rural Residential), the property allows a variety of uses, including single-family residential, hobby farms, group homes, and community or recreation facilities. Whether preserved as an irreplaceable estate, thoughtfully enhanced, or reimagined for future generations, opportunities of this size and significance anywhere in the US are exceptionally rare.
