This picturesque “stone town” in southern Ontario has a rich architectural history and it is next on our list for fun summer day trips! St Marys, Ontario has over 25km of outdoor trails and is a small town getaway.

The town of St Marys is located almost two hours away from Toronto, between Stratford and London.

It’s filled with natural beauty and a lot of charm. If you’re looking for a new small town to explore, St Mary’s has a ton of local shops, restaurants, parks, and scenic trails.

It is also known as “The Stonetown”, according to the Town of St. Marys, due to its historic limestone architecture.

“Many 19th-century limestone structures still remain including but not limited to churches, commercial blocks, and private homes,” shares the site.

But that’s not all that remains. A limestone quarry that was abandoned in 1930 is now a popular swimming spot in the summer – Canada’s largest outdoor freshwater pool.

Though there are a few things best to enjoy in the summer, the town’s hiking trails are your best option for the fall season.

Whether you decide to go on a walk, bike, or run along its in-town trail systems, you’ll be treated to a scenic experience of the local landscape.

Out of the four trails, the Grand Trunk Trail offers panoramic views over the town and countryside thanks to the Sarnia Bridge, according to the town’s site.

Though it’s only 3.2 km long, it started out as part of the historic Grand Trunk Railway. “In 1858 the GTR reached the village of St. Marys from Toronto and points further east,” states the town.

“From St. Marys the line went west to Sarnia, Port Huron, and Chicago.”

This sounds like an amazing adventure!

Now head outdoors and enjoy this beautiful town.
