Bwlch y Cloddiau: a steep paved road to the summit
Bwlch y Cloddiau is a mountain pass at an elevation of 533m (1,748ft) above the sea level, located in Powys, in Mid Wales. It’s one of the highest mountain roads of the country.
The road to the summit is asphalted but pretty narrow. There are some narrow sections -scarcely wide enough for two cars- where if two vehicles have to pass each other, one might have to reverse for some kilometers of winding narrow road to get to a place wide enough to pass. It shouldn’t be attempted by those who don't know how to reverse.
Starting from Troedyrallt, the ascent is 3.0 miles (4.82 km) long. Over this distance, the elevation gain is 250 meters. The average percentage is 5.18 %. The road hits an 11.8% of maximum gradient through some of the ramps.
