There is something undeniably exhilarating about cave exploring. A sense of wonder and mystery accompanies the ancient caverns, drawing us in and connecting us with an ancient time. Our voices and footsteps echo in the void, bouncing off rocks and adding to the sense of intrigue.

The rock formations in Ontario are nothing short of dazzling (all thanks to the Great Lakes). The Great Lake region is filled with a variety of cave systems, from deep caverns that tunnel underground, to vast open crevices that open to the sky above.
