Ontario cave exploration enthusiasts are travelling to Renfrew County this summer to visit the Bonnechere Caves, a vast underground limestone system located near Douglas. CTV's Dylan Dyson profiles tour guide Lucas Rosandic, who takes visitors through geological formations created during the Ordovician time period hundreds of millions of years ago. Tourists Josh Shollenberger made the stop during a road trip through Eastern Ontario to see the stalactites and learn about the explorers who first navigated the system in the 1950s. The site sits along the Bonnechere River and offers guided tours for $25 per adult.
