Here are my suggested routes for different abilities:
Just keep south of Jollies Pass Road, the Heritage Forest is flat so can be ridden by kids to elderly
Easy Rider is a 6km loop that everyone can do.
You can tag on Perseverance for an extra 1.5km.
Lastly add Snakes n Ladders if you want some easy but challenging turns.
Area just north of Jollies Pass Road has some slope without being too extreme.
Mach 1 is a good starting point onto Western Link and then up Swamp and down Swoop.
For some extra try Swamp and Swoop as a loop another time?
Steeper area behind Conical Hill is best, go up Clarence Valley Road, then start
Tank leading onto Yankee Zephyr or miss YZ and go straight to Tombstone.
Finish back with Big Foot and then Detox before heading back on Dog Stream.
If you really love steep downhill then you already know about:
Eagles Nest leading onto C Line
If you don’t value your life then go for Addiction !
