There is perhaps 15km of singletrack in Hylton Park. Most of the tracks are two-way and the signs are sketchy so it's not particularly visitor friendly but it's not huge so you're never lost for long. Just head up towards the top and find a likely looking track heading down. There is nothing extreme that isn't avoidable. Some work has been done developing jumps and other fun stuff but most of the riding is old-school - it's good if not whoopee.
