Boischatel cave

This is Canada’s longest cave east of the Rockies.
Approximately 3,000 metres long, it is known.
Its network of galleries was carved out by the waters of the Little Ferrée River, which flow down to the Montmorency River near the waterfall of the same name.
The Boischatel caves are managed by the Société québécoise de spéléologie, with whom you must contact in order to visit the caves.
