Caving in Montréal is a rare opportunity to discover an unsuspected underground world in the very heart of the metropolis.

After a thorough briefing, you'll venture into the depths of the earth for the exploration.

The route of this introductory caving experience in the Saint-Léonard Cavern takes you through the historic section of the cave as well as a newly discovered zone uncovered in 2017. You'll have the rare privilege of observing the water table beneath Montréal — a captivating sight that perfectly illustrates the crucial role caverns play in our natural environment. If you choose the adventure trail, you'll also discover an aerial section of the cave that requires you to progress on rungs hooked into the rock face.
