Firetrail of the cruisy kind, with just a smattering of rocks (flat stuff and just a couple of tiny climbs if I recall).

The summary pretty much eludes to the fact this short ride isn't really worth getting out there for on it's own. Unless the 6.6Km return is your thing? If not, it can be linked with others in the area. The North End is almost exactly 2km from the North end of Duck Hole for example. At the other end, the distance is more like 1Km (and another 1600m get's you to the end of the Perimeter Trail.
