Big Shag Lake is part of the Big Island Lake Wilderness area in the Hiawatha National Forest, which connects several small lakes via portage trails. The network of lakes makes it a popular multi-day paddle route, with portages linking Big Shag to neighboring wilderness lakes.
Big Shag Lake is shallow and located in the Upper Peninsula, so it freezes reliably and early. Ice fishing is possible, though the remote access and wilderness setting mean you'll need to plan for unplowed roads and limited services.

Big Shag Lake sits in Marquette County deep in Upper Peninsula wilderness — the kind of place people describe as "where you go when you want to not be found for a day." It's part of the Big Island Lake Wilderness area, which means portaging, paddling, and genuine seclusion rather than marinas and jet skis. The lake is reportedly shallow, with small northern pike, medium-sized bass, and panfish making up the fishery. Don't come expecting trophies — come expecting loons, wildlife, and miles of quiet water.
There's one launch with easy in-and-out access, and reviewers consistently praise the remoteness and scenery over the fishing. The surrounding wilderness area connects multiple small lakes via portage trails, making it a solid destination for a day or multi-day paddle-camping trip. Nearby camping options include Anderson Lake West State Forest Campground and Bass Lake State Forest Campground, and the Elemental Resort provides marina and beach access in the area. Despite the backcountry feel, the single launch apparently sees enough traffic that it can feel busy even midweek during summer — a testament to how word has gotten out about this "kept secret."
