Overview· 20800 Horseshoe Island Frontenac

MLS® #X13730656

Offered for only the second time since 1932, Horseshoe Island is a rare six-acre private island located within the Frontenac Arch Biosphere, a UNESCO-recognized region celebrated for its natural beauty, wildlife, and interconnected waterways. Carefully reimagined for modern island living while preserving its timeless Canadiana character, the property combines authenticity, comfort, and connection. Beautifully furnished and thoughtfully curated throughout, it features inviting accommodations, welcoming gathering spaces, refreshed guest retreats, and countless touches designed to make every stay memorable. Designed to accommodate guests, the property comfortably sleeps more than 15 people. Features include a main lodge with a bright great room and expansive lake views, a loft bedroom, a separate three-bedroom wing, three bunkies, ample tenting space, generous shoreline access, and outbuildings suited for storage, workshop, or creative use. A dedicated mainland boathouse and four-car garage beside the public launch in Battersea provide exceptional convenience and ease of access. Loughborough Lake is renowned for boating, swimming, paddling, and excellent fishing, while the island itself offers an extraordinary sense of privacy surrounded by Crown land, forests, shoreline, and open water. Warm, welcoming, and deeply connected to its history, Horseshoe Island remains a cherished Canadian retreat where people gather, reconnect, and create lasting memories in a setting that feels both timeless and increasingly rare.
