Bwlch y Groes, Gwynedd, Wales
From the southern shore of Lake Bala, a steep and narrow road winds through gorse and heather-covered mountainside towards a small gravel car park beneath a commemorative iron cross at Bwlch y Groes (Gospel Pass). At 545m (1,788ft), this is Wales’ highest public road, built along the route of a medieval pilgrimage trail that once headed through the Aran Mountains towards St David’s. In the 1930s, the summit marked the finish line of a hotly contested hill climb competition, where Britain’s foremost motor manufacturers raced their sportiest models up these punishing inclines. Thankfully, these days, things are much more sedate, with only the occasional bleating sheep (or panting cyclist) to disturb your car park picnic and views over Snowdonia.
