Trail Description

Summerstown Trails 10, 14, 15: The trailhead has a large map outlining the trails and uses for each. There are several different combinations possible. Hiking the 10, 14, 15 route is a beautiful 3.5kms through woodlands. Even though there are several intersecting points, the trails are clearly marked with yellow signs to guide you. The path itself is narrow (one person only) and lined with trilliums. There is a rest stop along the 14 at the major intersection (you’ll know it when you reach it). Like most trails in Ontario with wetlands, it can get buggy in the summer. Not horrible for the spring though, as long as you have bug spray. The fall and winter are best, but that’s a personal bias for bug free hikes! The most loved aspect of this trail system is that a) it’s vast, allowing you to choose how long to hike and b) you can fully immerse yourself in nature here. Another bonus? All-the-trilliums in the spring.
