Dungog Common is a MTB area next to the township of Dungog that comprises 650 acres and currently about 30 Km of MTB single track mostly blue and some black. I would call it a hard XC track or AM track. Ideal for Gravity Enduro.
You need to enter via Common Rd, cross cattle grid and park right there or drive along Common Rd (the gravel part) for another 2 Km and park at the grassy flat where all trails start.
There are no facilities at the Common, however change rooms and showers are available at the showground and toilets are available next to the council building in the main street called Dowling street.
