This area is referred to as the East Duffins Headwaters area and is, by far, the most extensive with over 100 km of trails spread over the 1,000 acre Durham Regional Forest main tract, and the 4,000 acres of conservation land.

The East Duffins Headwaters area contains mixed sections of hardwood and deciduous forest ranging from flat to hilly topography, and is renowned for its hiking, cross-country skiing, mountain biking and horseback riding.
