20800 Horseshoe Island (Loughborough Lake) - South Frontenac, ON
$1,450,000
Two Properties. One Seamless Island Experience.
For those seeking ultimate privacy, convenience, and natural beauty, what could be more
perfect than the rare combination of a private island with a private mainland boathouse and
garage, on a premier lake in a UNESCO-designated region of central Canada?
At 20800 Horseshoe Island, ownership includes not only a private island retreat, but also a
dedicated mainland boathouse and four car garage beside the Battersea public
launch—providing a practical, weather ready starting point for every trip to the island. Together,
these two properties form a rare and seamlessly integrated offering: welcoming, uniquely
Canadian, and offering a true sense of escape.
Arrival & Access – Where island life begins: park, launch, and set course.
Your experience starts on the mainland at a highly soughtafter location directly beside the
Battersea public boat launch. Here, a four-car garage with an attached boathouse supports true
island living, offering secure storage for vehicles, boats, and lake gear, making arrivals,
departures, and daytoday logistics smooth and efficient.
Island Living – A private 6-acre retreat surrounded by open water, Crown land, and tranquility.
From the boathouse, a short and scenic boat ride leads to the heart of the offering: your private
6acre island, surrounded by untouched Crown land and uninhabited islets, offering exceptional
privacy and a setting reminiscent of a provincial park.
Held by only its second owners since the 1930s, who have lovingly maintained and restored it,
the island comfortably accommodates over 15+ guests. It’s ideal for extended family
gatherings, quiet getaways, or even corporate retreats. The main lodge features a sunlit great
room with vaulted ceilings and expansive lake views, while generous shoreline access keeps
swimming, boating, and fishing just steps away.
Sleeping accommodations include a loft bedroom, three additional spacious bedrooms, and a
serene primary suite, along with two hilltop bunkies. A separate hideaway bunkie sits at the far
tip of the island, complete with its own dock, firepit, and wideopen views, accessible by foot
through the woods or a paddle around the point. The property also includes two outbuildings, a
pumphouse and a large storage shed, with endless possibilities for workshops or creative use.
Together, the mainland access point and private island create a rare, wellbalanced
offering—easy to reach, quietly selfsufficient, and deeply connected to the landscape.
Location, location, location!! – On Loughborough Lake in Frontenac Region
All of this unfolds on the shores of Loughborough Lake, less than half an hour north of the
historically significant and culturally lively city of Kingston and The Thousand Islands.
Loughborough Lake is widely regarded as a premier lake in Frontenac Region, valued for its size,
natural character, and long established cottage community. With approximately 24 kilometres
of length and an extensive, varied shoreline, the lake offers a sense of openness and scale that
sets it apart from many nearby lakes.
A mix of private islands, Crown land, and protected shoreline helps preserve natural views and
limit overdevelopment, contributing to a quieter, more traditional cottagecountry feel. Well
known for excellent fishing, along with swimming, paddling, and boating, Loughborough Lake
remains a consistently desirable destination for those seeking an expansive and enduring lake
experience.
What’s even more remarkable is that sitting in the heart of Frontenac Region, the home of
Loughborough Lake, is the Frontenac Arch Biosphere. It’s a UNESCO designated natural
convergence zone where five major forest regions meet — making it one of the most biodiverse
places in Canada. Location, location, location, indeed!!
