Thanks, for the info.

I called the Muskoka airport today - they confirm that no scheduled flights go there (which is what I was really asking with the thread) - charters do go there, and of course the airport services pilots with private planes.

As I have not been to Algonquin Park, and as my wife and 6 yr old daughter will be accompanying me, this will be an enjoyable trip (my wife can share the driving, my daughter will like the wildlife, including the moose in the park - how often do they cross the road?).
