For some future research what trails are on offer for the Newcastle area....
Preferably a ride from town ir a max of a 20min drive...
Hey Grip - sticking to your brief and assuming you mean the cbd area (the city/town is pretty spread out):
- glenrock is an easy ride from the centre of town. On the way back it is right on top of Merrewether beach for a swim and refreshments at the cafes, bar, and pub there. It offers a pretty easy xc/am single track network of a few kms and some run down dirt jumps (still fun though).
- mount sugarloaf offers a few bits of fire road and single track. Plenty of fun and better if you can shuttle cause it is a steep bitch.
- Killingworth is the old home of the local club. They recently hosted a nostalgia race there. It's got an xc and easy dh course.
- Jesmond park offers a bit of fun single track. Bike path to the top if you are lazy and bomb down.
There isn't much else close by, a few secret locations if you want to risk death...Awaba and Ourimbah club trails are both more than 20min drive away. Ourimbah is easy to get to by train, but will require a bit of a ride on the road. I prefer Ourimbah. If you end up down around Awaba there is also a lot of other trails in the Wattagan mountains. There is apparently some trails around Patterson and Dungog, I've never seen either so don't know.
There is currently a fairly large amount of cycle way as well. It runs along the harbour and a few beaches.
