PS Unless you are in a particular rush to get to Orillia, I would recommend that you
budget for some additional time in Georgian Bay. Orillia, on Lakes Simcoe and Couchiching, is quite pretty but crowded.
Georgian Bay is often referred to as the best fresh-water cruising grounds in the world and for good reason, in my opinion. The
water is extremely clean (still potable in some areas!) and there is some breath-taking scenery as well as countless protected and beautiful
anchorages, already referred to. The water in the North Channel, while incredibly clean, can be somewhat chilly for swimming, but the southen end of the bay (south of Parry Sound) should prove quite inviting by late July. There is also an area of national parks and if you have
children, the one on Beausoleil Island is particularly appealing since it has Park Rangers who conduct nature tours, an outdoor theatre and some other basic facilities.
There is a terrific Cruising Guide to Georgian Bay that is available at any
marine store (and many marinas) that will provide additonal assistance in terms of
navigation,
anchorages and shoreside facilities, etc.
Enjoy!
