One of the most unusual sights in mid-Wales: three bridges stacked directly on top of each other over the Mynach Gorge, where the River Mynach plunges down a series of spectacular waterfalls before joining the Rheidol. The gorge is about 20 kilometres inland from Aberystwyth, and the easiest way to reach it is on the Vale of Rheidol Narrow Gauge Steam Railway, which makes the journey into a destination in itself.
From the upper bridge, a path descends through the gorge to viewing platforms over the falls. The lower path (Jacob's Ladder, a steep stone staircase) gives the best views of the lowest waterfall. The whole walk takes about 45 minutes and is fairly strenuous on the descent. The Devil's Bridge Hotel at the top serves food and has sat here, overlooking the gorge, since the 18th century.
