Explorers Discover A Sprawling Secret Pathway Hiding Right Beneath Montreal

Having Google Maps in our palms at all times can make us feel like there’s nothing under the sun that hasn’t been discovered. But for two explorers in Montreal, Canada, there wasn’t anything further from the truth. Daniel Caron and Luc Le Blanc grew up near a mysterious cave in the Saint-Leonard borough of Montreal. To them, the site was far more than a teenage playground — it was a keeper of ancient mysteries.

Saint-Leonard Cavern

In 1982, Montreal authorities grew tired of chasing away teenagers who were illegally exploring Saint-Leonard Cavern, so they came up with a genius plan: put a gate on the front entrance and start charging money for entrance. Soon, over 70,000 people had received a sterile, safe tour of the caverns — which bothered spelunkers, Daniel Caron and Luc Le Blanc.

Under the Center

See, the center of Montreal is a bustling cityscape with beautiful French details. But there was a whole world underneath it — linked together by the Saint-Leonard Cavern. By so closely controlling who could go in and out, authorities were limiting the potential discoveries.

Trouble with the Law

As a teenager, Daniel had spent countless hours climbing around the caves. There was something magical and otherworldly about them, and he couldn't resist seeing how far he could go into its unexplored depths. He was one of the many kids that police were always chasing away from the vast caverns.

Something More

After decades of exploring, Daniel became convinced that it wasn’t just the cave that was worth looking into. He was convinced something was lurking deep beyond its walls.
