I hiked on the Bruce Trail north of Burlington, from km 82.1 to km 61 on Map 9 of the Bruce Trail Reference 26th edition, and then back to my car, for a total of 42.2 km. This route was all trail, no roads, with lots of ups and downs, and provided views of Lake Ontario, Hamilton, and two waterfalls.
I parked beside Guelph Line near Sideroad 1 (lat 43.38896, long -79.85498). Here is a link to a map the location: Map to Parking
