Welcome to Invernairn on Georgian Bay. The property consists of almost 12 acres and approximately 2,500 feet of shoreline on Georgian Bay forming the southern peninsula of highly coveted Mowat Island. Built by locally renowned builder Ron Bowman, the family compound features a 4-bedroom main cottage and 3-bedroom guest house both with jaw dropping views overlooking the quiet eastern shoreline of Huckleberry Island including the notable landmark, Hole in the Wall and both on their own septic systems. The main cottage features an open concept with vaulted ceilings and large windows allowing for an abundance of natural light. The centre of the cottage is anchored by a massive floor to ceiling wood burning fireplace constructed from locally quarried granite. Off of the kitchen is a screened sun porch with remarkable views and is a favourite gathering place in the summer - large enough to accommodate family & friends. A wooden boardwalk provides connectivity between the main house and guest house while still allowing for ultimate privacy. The property is heavily treed largely with Jack Pine, Oak and Hemlock. There is a Forest Management Agreement in place on the property thereby assuring significant tax relief. The lush vegetation supports a vibrant bird population, as well as fox and deer. Well groomed trails throughout the property offer opportunities for walking and hiking. A golf cart is employed to transport luggage and supplies from the harbour to the cottages. The property also features a long protected sandy beach, perfect for children and rarely found on Georgian Bay. Mowat Island has tremendous history and was originally home to a grand Georgian Bay Hotel operating during the late 1800's in the peak of passenger steamships. Now the property is spotted from large cruise ships sailing the Great Lakes & beyond.
