I would have said East Hereford too but it aint that close of mtl....really not! (at least 2.5h)
Otherwise, Chanteclerc (in the Laurentides section on the trail page) is closer but don't know if difficult enough for you... If you dont wanna go to East Hereford, I would go there (maybe 45min from mtl?!).
But if you go, go today cauz it will be raining for a week or so, againn!!!!
