Mountain Bike Course Forest Hill is a council-run off-road racing and dirt jump track at 253 Forrest Hill Rd, Forrest Hill, on Auckland's North Shore, rated 4.4 from 21 Google reviews. Reviewers call it a great track with proper jumps and note a recent fix-up that has it running well.
Dirt jump courses are built from shaped soil, so they ask something of the rider: lips and landings dry out hard and dusty in summer, and most regulars wet the take-offs before a session rather than risk a harsh bounce. After heavy rain the same soil ruts, and a good venue closes or repairs lines until they set again. It also pays to notice how a park sits with its neighbours — bush regrows across neglected lines quickly, and the best tracks survive on dig days and council upkeep between them.
For riders around Forrest Hill, a jump park this close is an easy after-school or after-work habit.
