Marathon Waterfront
On Lake Superior's north shore beside Penn Lake and the wilderness of Pukaskwa National Park.
Overview
A town between the waters
Marathon is a friendly town of about 3,100 perched on Lake Superior's north shore in the Thunder Bay District, right next door to Pukaskwa National Park.
Penn Lake sits within town as Marathon's largest green space — calm, swimmable water you can reach on foot or by bike, with a park, beaches and boat access.

Beyond Penn Lake, Lake Superior's pebble beaches and the mouth of the Pic River draw paddlers, anglers and swimmers all summer — a rare mix of a sheltered local lake and one of the world's great lakes minutes apart.
Marathon is a working community with small-town prices, which makes waterfront here far more attainable than southern Ontario. Inventory is modest, so check the live listings for what's currently available.
