My parents used to go to Oba lake, back in the 60’s.
I went to Wabatongushi lake, Ontario
We never went to Wabatongushi Lake. Just Oba (by rail) a couple times (only once I was old enough to really recall), and a few years later, we flew into Granite Hill Lake. Of course, Ontario has a LOT of those beautiful lakes!
Somewhere on the way to Oba by train, IIRC, there was a quite high trestle curving over a dam(?) and I think some sort of powerhouse in the valley below? I recall everyone rushing to one side of the train car to gander at the view, and the car actually tipped a bit — not very reassuring!!!
Early 60’s for my family (at least the trip I recall).
