I have done fly-in's for 30+ years and there is not a better week for me. I agree with WINI and most outfitters can supply a marked up map with good fishing spots .I would also ask the outfitter for references for the lake you plan on fishing. Make sure the reference has fished the time period you are planning to go. Good fishing locations can vary greatly from May/June vs. the end of July-Aug. Some folks think they can just get dropped off on a Canadian lake and fish will jump in the boat all over the lake. Fishing moving water, wind blown shorelines, good structure is still key to catching fish (just like in WI).
Our group has used Clarks Resorts the last 8-9 years and have fished 5 of their lakes. Fishing has been good to outstanding at each location. Going back in May/2023
