I have only ridden this trail once during the 3 ring circus but from my only time there i enjoyed it greatly. It does have a lot of fire trails but it does also have some grade a flowing singletracks. The beauty of it is you can do some climbing on the fire trails and when you get bored you can drop right on in to the singletrack for a bit of recovery and fun. It also seems that all the singletrack is 90% downhill which makes it even better!
Reading trailflix also tells me that it is one of the earlier trails available to most Sydney riders so there is a little bit of history there too. The drive down is however a little further than most can manage in the mornings so it is best left for a Sunday. Might organise a ride down there soon as it is definitely worth it!
