A loop walk at the top end of Mullans Road beneath the south face of Mt Isobel.
Fir Trail is a remarkable short walk that passes through dense stands of fir trees, including soaring Douglas fir, true fir, and larch, as well as out through open grasslands around the forest edge. The trail undulates through the plantations and has some good views.
Starting at the waterfall carpark, the Fir Trail is a nice easy downhill track. You can take the left track for a bit more riding.
