Climbing gyms in Chicago
Chicago climbs indoors out of necessity — five months of winter will do that — and First Ascent has built the city's backbone with full-service gyms from Avondale to the Block 37 bouldering spot right in the Loop. University walls (UIC) and park-district options fill the gaps. Deep-dish quads optional. Weeknights after 6 get busy in winter; lunchtime Block 37 sessions are the local cheat code.
