West Coast Riders Club MTB Trails is a cycling park at 550 Old North Road in Waimauku, Rodney, on Auckland's rural north-west fringe, and it holds a 4.7 Google rating from riders.
A good mountain bike park is judged less on trail count than on how honestly its grades hold up: when the easy, intermediate and advanced markers mean what they say, nervous beginners and jump-hungry teenagers both get a proper ride. Ground in this corner of Rodney grips hard through a dry summer and turns greasy fast after rain, so seasoned riders watch the forecast as closely as the trail map, and carry a spare tube because forest networks rarely have phone coverage.
On Old North Road at Waimauku, that puts graded riding within easy reach of north-west Auckland and anyone bound for the Muriwai coast.
