During mating season, visitors can witness a breathtaking scene: tens of thousands of snakes coiled together like a giant living carpet inside the massive snake den.
As the place with the highest concentration of snakes in the world, the Narcisse Snake Dens in Manitoba, Canada has become a tourist attraction – but not for the faint of heart.
The climate and geology of Manitoba make it an ideal habitat for snakes to live and mate, drawing tens of thousands of them here every year.
