Savage climb for which I’d recommend at least a 32t on rear. Oh and not doing it on a loaded bike😫 But what a view! And very few cars. Always a bonus. Relatively narrow tarmac. Bit gravelly nearer the bottom but gets smooth and dry once above the trees.

Be prepared for a good hour's hike-a-bike over football-sized gravel, with parts submerged under deep pools even on a dry day in July. It's called rough stuff for a reason :)

It’s a pretty tough climb popular with cyclists. There are 2 routes to reach the pass. From the west side (from Llanbedr-Dyffryn-Clwyd) the road gains 260 metres (853 feet) in altitude in just 2.25km (1.4 miles), the first half of which is at a gradient approaching 25%, followed by an even-steeper hairpin bend before the gradient finally eases slightly. 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. The other route, the east side, has a less severe gradient, but from the summit it is dead-straight for over a mile downhill, which provides an exhilarating descent for cyclists who have struggled up the pass from Llanbedr. Its location also makes it an ideal segment to link up with other climbs in the area, including The Shelf and Horseshoe Pass.
