The Historic Nightcap Track is a 19km one-way hike in Northern NSW, Australia. It can be walked in either direction, however, Caro chose to walk the (mostly downhill version) from Mt Nardi to Rummery Park.
It hugs a ridgetop in the Nightcap National Park (and some of Whian Whian Conservation Area) that divides the Tweed Region from the Byron Region.
