A lesser known trail, tucked away in a small semi-rural suburb of Sun Valley located between Warrimoo and Valley Heights in the lower Blue Mountains area, the fire trail starts at Rosenthal Lane. 12.7km - Full track 289m Elevation gain 3.5–4hr Follow the unsealed dirt fire trail passing between large paddocks separated by electric wired boundary fencing before reaching some bushland. The trail enters into a cool temperate fern gully forest as it follows Valley Heights Creek. The tree ferns and ground ferns dominate the understorey of valley floor creating a canopy of sweeping green ferns as far as the eyes can see - absolutely beautiful. This trail is relatively easy in most parts with moderate climbs towards the end which young children could easily manage.
