Bwlch Penbarras, Denbighshire
The picturesque backdrop of Moel Famau and the stunning views provided by this north Welsh ascent do little to mask it’s fierce ramps.
More than two kilometres in length, the climb is introduced softly but very quickly begins to rise steeply, reaching a fearsome crescendo as it bends left on a huge 25 per cent hairpin.
With an average gradient of 11 per cent, the ascent is a popular one for cyclists in the region and features as part of the Dave Lloyd Mega Challenge sportive, one of the toughest rides in the UK.
Its location also makes it an ideal segment to link up with other climbs in the area, including The Shelf and Horseshoe Pass.
