★★★★★ Climbing in Montreal is a sacred thing. I don’t know who decided that this city would sport the best climbing gyms in North America, but I thank the lord they did. In terms of bouldering, having been a patron of as many gyms as possible, in as many countries as possible, none are on par with the Bloc shop. Sure it can get crowded at peak hours, but the space is about as nice as you could possible get for bouldering. The routes are constantly changing and interesting for everyone from the best climber to your first timer mom and dad. The staff are Montrealers, so a good mix of hip, nice, smart and arrogant. The prices are competitive, the location is fine and to top it all off, the chalk is free. Seriously, if you are looking for a gym in montreal, membership or one time thing, go here.
