Lake Gratiot is the largest inland lake in Keweenaw County, Michigan, covering 1,438 acres with a maximum depth of 70 feet. The lake boasts some of the wildest shorelines in the Keweenaw, with nearly three miles protected by the Gratiot Lake Conservancy. A DNR boat launch on the northern side provides the primary access point for paddlers. The lake's size, comparable to Otter Lake, means paddlers should be prepared for potentially choppy conditions, especially on windy days.

Wildlife viewing is a highlight, with paddlers likely to encounter various species throughout their journey. The Noblet Field Station, managed by the conservancy, offers educational programs during summer months that may be of interest to paddlers wanting to learn more about the lake's ecosystem.

For a unique perspective, paddlers can hike to the Gratiot Lake Overlook before their trip to scout potential routes. The lake is known for its fishing opportunities, with large northern pike, perch, tiger muskie, and walleye attracting anglers.

When planning a paddling trip on Lake Gratiot, it's essential to bring sunscreen, as summer sun can be intense and long-lasting in this northern location. A life jacket is required safety equipment. Paddlers should also pack water, snacks, and consider bringing a GPS for navigation on this large lake. To prevent the spread of invasive species, thoroughly wash any watercraft brought from other areas before launching.

The lake's location south of US-41 at Central on Gratiot Lake Road makes it accessible yet removed from major tourist areas, offering a more secluded paddling experience compared to some other Keweenaw lakes.
