Big Siskiwit River Kayaking Guide
The Big Siskiwit River is an 8.1-mile river on Isle Royale, flowing west to east across the southern part of the island and entering Lake Superior at Siskiwit Bay. Isle Royale is a national park with no roads and no vehicles — the river is reachable only on foot, by canoe, or by paddling in from the lake, after arriving by ferry or seaplane.
Isle Royale's canoe routes are built around its inland lakes and portages, not its rivers, which are generally shallow, beaver-dammed, and choked with deadfall. No established paddling route, mileage, or difficulty rating is documented for the Big Siskiwit River.
For the paddler who makes the trip, the reward is wilderness: moose, loons, and one of the least-developed paddling environments in the Midwest. But the Big Siskiwit itself is a park river to be appreciated on foot or from the water's edge, not a documented river run.
