Extension Ridge is an XC trail network between Harewood and Extension, in the south of Nanaimo. The area is primarily singletrack on rock that runs north to south on successive parallel ridges with connecting trails between ridges. It has seen significant logging activity in recent years, but still has many beautiful spots worth visiting, including the locally famous "Abyss", an earthquake fissure that you wouldn't want to fall into.
Primary Trail Type: Cross-Country

Access Info:
There is a trailhead on the north end of the network up Harewood Mines Road a little ways past the highway overpass and another on Extension Road to the south.
North entrance: When you reach some cement barriers on your left park and ride up beside the steps on the right a little ways down the logging road. Keep right until you see a sign for the Trans Canada Trail. This is the start of the Abyss.
South entrance: Following Extension Road west you will pass Cinnabar Drive to your left. Continue 500m along Extension Road until you see a gate on your right. Park along the road by gate and head along gravel road west to enter Hootenanny or north under the powerlines to enter Potsticker.
