Only 2 hours South of Montreal (5 hours North of NYC) is Poke-O-Mooshine. As it says on Mountain Project, it's an impressive cliff for the Adirondacks. Or for the East at all, for that matter. A large selection of quality trad routes, some bolted routes (but tend to be 'sporty').

We'll carpool and/or rent a car for the day. We will leave Sunday morning at 8:00am and return late Sunday night. Ensure you have a valid passport, for travel into the US.

Note the PEREGRINE CLOSURES on some routes - Here are the closures:   http://www.dec.ny.gov/outdoor/7870.html
