To view the stunning gorge and three bridges, it costs £2 per person. There's a small free car park and a café for refreshments. The path is very narrow and consists of steep stairs. Not suitable for unfit people. It only takes 10mins to complete the short loop. The three bridges show a history of crossing the gorge through the centures. The first and lowest bridge was built by monks in 11th century. Around 1754 a second bridge (middle bridge) was built on top if the first, with ornate iron railings. In 1901 the third bridge was built, again with a modern copy of the iron original railings.

Well worth stopping and admiring if enroute and depending on your love for engineering may well be worth the detour, too.

Devil's Bridge is a well known tourist highlight in the heart of the Cambrian Mountains. You can view the bridges from the road, but there are also 2 walks for which you can pay a small entrance fee. The walks take you through the gorge to spectacular waterfalls, the longer walk is along steep and uneven natural stone steps - not one to try in your cycling shoes!

Be prepared for the steep descent down Jacobs Ladder over a hundred steep steps down a very steep angle down. Then followed by and equally steep return, don’t race back up, take your time and don’t be afraid to go slow, this is in total 600 steps down and the same back up, it is a very steep and narrow gorge, giving breathtaking views, just remember to keep breathing and stay calm!
