Chesney Wilderness Area is a 93 hectare (230 acre) natural area located in Oxford County east of Woodstock, and just north of exit 250 off Hwy 401 near Drumbo. The Hemlock Trail, as reflected by its name, is special because it passes by a large number of mature hemlock trees. The path begins at a parking lot where there is an information kiosk with a map. The trail has a hard earth surface with occasional tree roots and hills farther into the woods. There was formerly an extensive boardwalk through the bog, but this was removed in September 2009 for safety reasons, making the trail now approximately a 1.9 km loop.
