Garden Brook connects Lake Fanny Hooe to Lake Superior just 800 feet to the north, making it one of the closest inland lakes to the big lake in the entire Upper Peninsula. The lake sits in the Lake Superior watershed at the tip of the Keweenaw Peninsula, with Copper Harbor's natural harbor immediately to the northwest.
At 40 feet max depth and 227 acres in the Keweenaw Peninsula, Lake Fanny Hooe freezes reliably and early — this is some of Michigan's coldest, snowiest territory. Ice fishing is possible, though it's not a major destination fishery. Be aware that Keweenaw winters are extreme with heavy lake-effect snow, so access can be challenging.

Lake Fanny Hooe is a 227-acre lake tucked between Copper Harbor and Lake Superior at the very tip of the Keweenaw Peninsula — literally the end of US-41. With a max depth of 40 feet and a roughly two-mile length, it's a small, scenic paddle lake flanked by Fort Wilkins Historic State Park on its north shore. Garden Brook connects the lake to Lake Superior just 800 feet to the north, which means you're camping between two bodies of water in one of Michigan's most remote and beautiful settings.
This isn't a powerboat destination — it's a kayak-and-SUP lake with calm water, forested shoreline, and historic fort buildings adding character to the view. Fishing runs to sunfish, bass, and chub, mostly casual stuff off the docks and shoreline. The real draw is the location: Copper Harbor is the jumping-off point for the Isle Royale ferry, Brockway Mountain Drive is minutes away, and the Copper Harbor mountain bike trail system loops around the lake. People who love Copper Harbor tend to love it obsessively — this lake is a quiet centerpiece of that whole scene.
