Hey Fardad, apologies about the delay. That post was from November but I’ll definitely be heading out that way again in the fall. To my knowledge Val-David is challenging to get to without at car (I think Autobus Galland technically stops there but its extremely infrequent) however the trails at Oka are easy to get to without a car if you take the AMT train to Deux-Montagnes and then ride the last 12km (which should be a pleasant warmup)
