About 10 years ago, Cruising World magazine rated the Top Ten cruising destinations in the world. North Channel of Lake Huron made the list. I don't recall any other Great Loop areas making the list. Others included the Greek islands, the British Virgins, Fiji, etc. My recommendation for 6 weeks would be to trailer to the southern end of Georgian Bay and cruise north in the 30,000 island inland route and go all the way to the Benjamin Island group in the North Channel. Two weeks would be enough to get there and two weeks to double back and catch what you missed the first time. I've gone on 1 week trips on most of this area with our 26' trailerable boat. Outstanding scenery, secluded anchorages, interesting communities, extremely friendly people, crystal clear water. There is an excellent cruising guide available to the North Channel and Georgian Bay. Ed
