The Torrance Barrens Main Trail is a short walk into another world. This three-kilometre loop circles shallow Highland Pond inside the Torrance Barrens Dark-Sky Preserve, crossing a boardwalk to a granite ridge viewpoint — and the landscape is like nothing else in cottage country. Glacial ice scoured this land down to bare Precambrian bedrock, rock between 1.5 and 2.5 billion years old, leaving a lunar sweep of stone, wetlands and stunted trees. Watch for rare Atlantic Coastal Plain wildflowers, beaver activity in the wetlands, and Ontario’s only lizard, the five-lined skink, basking on the warm rock.
The preserve itself is famous after dark: designated a Conservation Reserve in 1998, it became the world’s first permanent Dark Sky Preserve in 1999. With no light pollution for miles, the Milky Way spills overhead on clear nights and the aurora sometimes appears in late summer and early fall. The main viewing area sits right at the Southwood Road parking lot, so telescopes roll straight onto the granite.
The trail is easy, semi-wilderness and open year-round — bring sturdy shoes, bug spray in season, and respect the rattlesnakes that call the barrens home. By day it’s a geology lesson; by night, it’s one of the finest planetariums on Earth.
