This being the ragged North Shore, the trail can get twisty and hilly — especially near Split Rock — so let’s call the ride “slightly” difficult. A current detour of the Superior Hiking Trail also uses this stretch of the Gitchi-Gami.
Bonus: Admission to Gooseberry is free on a bike (the Department of Natural Resources will be happy to take your donation), and at a low-traffic hour I was able to gently ride the foot trails to the various viewing points for the upper and lower falls and the lake. It’s hard to get a good look at the 1909 lighthouse, however, without paying the $10 admission (worth it, of course).
No bike rack? J. Gregers Inn on Highway 61, just north of Gooseberry, was advertising bike rentals (call 1-218-226-4614 to confirm).
