Ontario consists of several outdoor swimming holes that are perfect for cooling off in the summer months. In Perth county, there's one cool swimming spot that was once a functioning limestone quarry.
The St. Marys quarry is Canada's largest outdoor swimming pool. It was filled with freshwater between 1930 and 1935; years before it was owned by the town. While it is a popular spot among locals, many people in the province have yet to experience swimming in it.
When the town bought it in 1945, the quarry saw several changes and improvements, including the addition of a new water trampoline, a large grassy area, sand volleyball courts, stand-up paddleboard rentals ($8) and a Tiki Hut that serves food and drinks. These elements create a unique experience that combines the vibrancy of a beach and the tranquility of a cottage destination.
Today, the quarry remains as a staple summer haven for locals and visitors alike.
Those interested in swimming at the quarry will be subject to various admission fees. A swim test, which entails demonstrating the ability to tread water for 3 minutes an swim 100 meters continuously, is also required. The quarry is supervised by a life guard
