Trails are made by mtb riders and for mtb riders, some of them are made from old paths and some are made from start to finish. If you really want to know the trails, be sure to contact Coast Riders who will take the time and give you a guided ride. Keep in mind that it would be good to donate something to the club, maintaining those trails isn’t cheap, and it takes a lot of beer and tools into making this kind of trails on these kind of surfaces.
If you don’t ride difficult lines and avoid most jumps, kickers, drops and gaps, then technical difficulty is 3/5. Trail Ponor is probably the most difficult of those trails and it is 4/5.
