A RARE DUAL-ACCESS PRIVATE ISLAND ESTATE - LAKE NIPISSING. A fully private 2.2-acre island paired with owned mainland boathouse and parking, just a 5-minute boat ride from shore. Few properties on this lake combine true island privacy with the convenience of deeded mainland access, protected docking, and modernized infrastructure. For buyers considering Muskoka, this is a compelling alternative. Extensively renovated and offered fully furnished, this turnkey 4-bed, 2-bath retreat features a primary ensuite, steel roof, new windows & doors, and an expansive glass-railing deck. Wall-to-wall windows and sliding doors at both ends deliver near-360 panoramic views and showcase the property's renowned west-facing sunsets.  The property features Culligan whole-home water treatment (softener, reverse osmosis, UV filtration & a heated waterline), heat pump, air conditioning, newer electric baseboards, and a wood-burning stove. A Briggs & Stratton generator with four 100-lb propane tanks supports uninterrupted power, backed by a full 200-amp electrical service (2023). The Septic was pumped in 2025, and both boathouses were shored up in May 2026. Nestled in a sheltered bay on Lake Nipissing's south shore, this is far more than a cottage: privacy, luxury, and self-sufficiency without compromise.
