Absolutely!! Lots of people walk it alone, including myself.

Yes.

When we spent a week in Bayfield (end of June), we didn't really look for bicycles to rent, but we did come across a small shop on Manypenny Avenue that daily brought bicycles outside and lined up for rental and service. Didn't stop and really check to see what the pricing was for rental. The shop was right next to a restaurant that we ate at twice (Maggies) that was a good restaurant (especially the fresh white fish - if you like seafood). We took the Brownstone trail from our motel and it was literally 5 - 10 minutes to Maggies & that bike shop. From the bike shop, probably 10-15 minute walk to the ferry area. Everything is really within walking distance around the Bayfield waterfront and the couple of marinas/harbors. At nite, it was really nice walking from town back to the motel with a full moon coming off lake superior. If you are planning on visiting that area, I would recommend it. We went on a sunset sail, went to the sea caves by water and hiked, took the water tour around all the islands. We didn't take the ferry to Madeline island, but I know you can rent bikes, mopeds on the island as well. I believe it is like a 15-20 minute ferry ride and runs pretty continuous from 7 - ??? probably at this point in the summer.
