A few people from the Oakville Cyclepath group went on a ride up there this past Sunday. I didn't go but, if your seeking some information for routes and such you can call Alan (leader) @ 905 338 0783 and he might be able to help you. There is supposed to be some good roads going up the mountain...

cheers

Oh I forgot...I was up there last summer and road along the rail trail....It was 55km one way if I remember correctly (Collingwood to Meaford??) but its pancake flat - hope that helps..
