What Scot said. The lake can change in an instant. Many people take that same trip, I haven't. Check in at Barkers island marina and ask around there. Also are you planning to stay someplace at the island or Bayfield? Gather up all your reservations and such before you start out. I know Washburn Marina is booked rater full much of the time, but guest dockage can be had for a couple days. The marinas at the island I'm not sure how full they get but since covid the lake/area has been rather busy. Not trying to discourage you, this area is beautiful!
