St Marys combines historic limestone architecture with trails along the Thames River and a unique history shaped by its quarries. The nickname “The Stonetown” comes from its limestone architecture. The Junction Station and the St. Marys Museum and Archives reflect different aspects of the town’s history. At the same time, the trails and quarries offer a variety of ways to explore the area. For planning, it’s especially useful to check specific routes, seasonal offerings, and the difference between West Quarry and St. Marys Quarry.
Limestone Architecture and Local History
Junction Station was recognized in 1973 for its national historic and architectural significance. The St. Marys Museum and Archives is housed in a historic home dating from 1854 and features exhibitions and materials on local history that have shaped St Marys. The cultural offerings therefore range from a recognized historic building to a museum whose exhibitions explore the town’s history.
St. Marys Quarry also has a history spanning several uses. It was once a limestone quarry that closed in 1920. In the mid-1940s, it was converted into a public swimming pool. Today, St. Marys Quarry is considered Canada’s largest outdoor freshwater swimming pool; operations may vary seasonally. Cliff jumping is one of its seasonal activities. This recreational history distinguishes St. Marys Quarry from West Quarry, which has different rules and activities.
Trails, Routes, and Views
The paved Riverview Walkway is 2.4 kilometres long. It starts in downtown St. Marys, runs along the Thames River, and ends at St. Marys Quarry. The Taylor Trail is much shorter, at about 0.25 kilometres, and passes through Rotary Park and along Trout Creek. The lengths provide a concrete comparison of the two trails, while their described routes lead to different places.
Another landmark is Sarnia Bridge on the Grand Trunk Trail. From the bridge, panoramic views extend south over the town and north across the surrounding landscape. For a longer route, the Loop Trail is another option: this in-town cycling route in St. Marys is 13 kilometres long. Overall, St. Marys has more than 25 kilometres of trails and parkland. These figures cover both short trails and a longer cycling route; the stated distances can help you choose the type of route you’re looking for.
The Difference Between West Quarry and St. Marys Quarry
West Quarry offers opportunities for fishing, paddling, and nature walks. It also offers views of the Thames River and the quarry waters. Fishing is allowed from April 1 to November 30, between sunrise and sunset. Swimming is prohibited at West Quarry. Check the posted rules before your visit. This restriction applies to West Quarry and should be distinguished from the seasonal swimming and recreational activities at St. Marys Quarry.
Seasonal Paddling
Through Yak Shack, seasonal paddling routes of approximately five kilometres are available on the Thames River and Trout Creek. Paddlers can see Sarnia Bridge on the Grand Trunk Trail from a new perspective or travel through downtown along Trout Creek. The season is currently over, and the offering is scheduled to return in 2027. This includes a free kayak loan program with single kayaks and paddles. The announced return is worth noting when planning if you’re considering paddling as part of your stay.
