St. Marys Quarry

St Marys Quarry has been our favorite swimming spot since we discovered it. Clean facilities, refreshing water, lifeguards. Cliff jumping is a hit for kids. Staff did a good job with reservation system during covid and I hope they will keep reservations for the years to come. As other reviewer suggested - three hours instead of two would be perfect. Free public tennis courts across the quarry is a nice bonus for tennis enthusiasts.

Excellent facility and wonderful place to cool off and have some fun doing it. Staff are friendly and professional. Definately a place to spend the day in southern Ontario.

Well maintained and beautiful location. I actually really like the reservation system as it prevents overcrowding. The only suggestion I have is if there could be a way to bump up the two hour limit to three instead (as time passes by so quickly when you are having fun!).

The Saint Mary’s Quarry is one of my favourite childhood memories! They have done a great job updating it and it continues to be great fun for the whole family! Apart from the swimming, they also have paddle boarding, volleyball and a snack bar! Their new trampoline and cliff jumping platform are great additions as well!
