The experience

“Wait, we’re going underground?” That was the first thing I blurted out when our guide, Marie, waved us toward an ordinary-looking set of stairs just off Sainte-Catherine Street. The air changed as soon as we went down: cooler, with this faint scent of coffee and bakery yeast drifting from somewhere. I could hear distant echoes of footsteps, but it wasn’t quiet exactly. More like a city humming underneath itself. Marie grinned and told us this is the RESO Underground City, not just tunnels but a whole network where people actually live their daily lives. I kept thinking, how did I never know about this?

We wandered through stretches of tiled corridors, past little bursts of public art (one mural looked almost like it was glowing under the fluorescent lights), and then up escalators into sunlight again. It was wild how quickly we’d pop back above ground: suddenly there’s the rush of downtown Montreal, street performers somewhere in the distance, buskers playing accordion. At one point Marie pointed out an old bank building with these carved stone faces. She said if you look close enough they all have slightly different expressions. I tried to spot them all but got distracted by someone’s dog wearing tiny boots (Montrealers really love their dogs). The pace felt steady but not rushed: about 4 km total, so you do need to keep moving.

I didn’t expect to laugh so much with strangers on a walking tour. There was this bit where Marie tried to teach us a few words in Québécois French. I absolutely butchered “dépanneur” and she laughed so hard she nearly dropped her notes. She also gave us a list of her favorite places to eat nearby (I still think about that smoked meat sandwich). There were moments when we’d pause in some sunlit plaza or catch our breath at an escalator, just watching people go by: students hurrying somewhere, office workers balancing coffees and phones.
