Mulmur 30th sdrd to Noisy River PNR. Map 21 of the BTRG. This route is mostly on the road so it's easy walking. The park section can be difficult in spots. Very rocky. Lots of crevices. And some stunning views. I hiked Noisy River from the north a few years ago but fell and had to turn back. So this was unfinished business for me. The road walk is very nice with little traffic. Walk on .
