Tarros Ladder and Carlon Head – Blue Dog Ridge – 23km loop
The first part of the trail is a steep incline followed by ladders and chains to go up. The Carlons Chains is not for the inexperienced. The NPWS lists it as a climbing route, not a bushwalking route . The latter part through Blue Dog ridge is an unmarked trail full of new trees popping up after bushfires. The loop ends with a path following Carolsons Creek back to Dunphys Campground.
Pros: great work out, fantastic views for the heads, great to see
Cons: Easy to get lost, can be boring to go for kilometers without lookouts and through a dense bush, at least 2 hour drive to the trailhead from Sydney
