Re: best time for cruising the 1000 islands?
I would lean toward early September since the crowds are gone, better winds, and generally decent weather. If going earlier check the date of the 1812 Overture by the Kingston Symphony. Great fun with real cannons and perfect setting.
Heading back to Lake Ontario for this summer. Ainia is back in North America for the first time since 2010. Currently in Long Island Sound.
