If you're looking for a challenge and to enjoy the full menu on offer at Buxton Mountain Bike Park, then the Big Kahuna loop should fit what you're looking for.
Picking up many of the highlights of the park including the super twisty and flowing Off Camber and the winding Acheron Ridge trail, the highlight has to be the Cathedral Trail. This is the final descent back to the car park so make sure you stop to enjoy the view and rev yourself up for the descent.
