    What this listing tells us

    Property description

    Discover an extraordinary opportunity to own a rare 32.14-acre luxury estate in the Blue Mountains, ideally positioned on the border of Collingwood and just minutes from Osler Bluff Ski Club, OslerBrook Golf & Country Club, Blue Mountain Village, and downtown Collingwood. Set well back from the road with a long, tree-lined driveway, this exceptional property offers remarkable privacy, natural beauty, and endless potential. Built in 1982, the stately stone residence presents an ideal canvas for those looking to create a custom dream estate with some views out to the bay in the winter. The grounds are truly spectacular. Highlights include a 56' x 25' PebbleTec pool with seasonal hot tub, poolside gazebo, pond, meadow, creek, and a private trail system winding through a mature forest. Silver Creek meanders through the East edge of the property, with seasonal salmon and Trout runs adding to the unforgettable natural landscape. Whether you envision a serene country retreat or a reimagined modern luxury estate, this one-of-a-kind property delivers unmatched location, privacy and scale in one of Southern Georgian Bay's most coveted recreational destinations. Your private retreat awaits. A must-see!
