The Grand Canyon walk in the Blue Mountains is a very popular 3-4 hour walk. What fewer people know are the little side trips deep into the gorge, away from the hoards and into the bosom of nature.
The start of the trip is a short cycle from Blackheath station in the Blue Mountains.
Start: Blackheath Station
End: Blackheath Station
Total distance: 20km

At the start of the Grand Canyon walk
The main path drops down into the valley. At two points, rather than following the sign to the canyon walk, go in the opposite direction upstream. It is beautiful.

A bit of scrambling over logs
You can only get so far going upstream until a swim is required. Being a bloody cold day, I made this the end of my little foray.
