The main ascent starts 800m from the cafe up the county road towards Abergwesyn. This 2km. track crosses the descending singletrack - watch out - taking you to the top of Bryn Mawr, where the trails from Llanwrtyd Wells join Coed Trallwm. Go round to the right where the track levels off, then drop right on to a fast single track left-handed traverse, switchback bend on to a right handed traverse before snaking down through the trees across your previous ascent. Continue till you dive off left for a tricky ride through ‘five springs’. Then pick your way down to the county road again with the cafe in front of you.
