Tucked away in the quaint town of St. Mary's, this limestone swimming oasis is the perfect place to spend your summer days. Located less than two hours from Toronto, the massive cove is filled with shining blue waters and surrounded by lush trees. St. Mary's Quarry is the best Ontario swimming hole and also the largest one in Canada, and with its scenic location, it might just be the prettiest too.
Bring your friends for a day trip and enjoy the many activities offered at the quarry. You can rent stand up paddleboards, and jump on the enormous 25-foot water trampoline!
If you're feeling adventurous, take a leap off the jumping cliff into the cool waters below. You can also ride down the water slide and try your hand at beach volleyball! Another interesting activity offered at the quarry is a 'water running class'. This is great for strengthening muscle and is a fun way to get a workout in. The classes are held on Mondays, Wednesdays, and Thursdays July - August, and cost $3 to participate.
Check out their calendar for special events such as 'Quarry Pooch Plunge'. On August 31 you can take your pup for a dip in support of the Stratford Perth Humaine Society.
Admission for the quarry is $4.75 for adults. You can also buy season passes! When you're finished swimming and sunbathing, you can explore the historic town of St. Mary's. There are lots of delicious restaurants and cafes to grab a bite at, as well as local shops and sightseeing.
