One of the best and only trails Thornhill has to offer. It is out and back in the forest along the German Mills Creek/Don River. Has a few small jumps, bridges, etc. and is maintained by locals, but can be slightly overgrown in the summer.
How to get there:
1) There is an entrance to a gravel path at end of Evergreen Crescent (closest intersection Sycamore Dr. & Bayview Ave.). Follow the gravel path for a bit and keep eyes wide open for the trailhead on the right (one trailhead before the bridge and another a bit after).
2)Access the other end of trail from Green Lane between Bronte Rd. and Kings College Rd. (south of passing over river)
3)There is parking at Huntington Park on Huntington Park Dr. Follow gravel path from parking lot and look to left side for trailhead.
