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.

Mwnt is consistently one of the best places to spot dolphins in Ceredigion, often seen swimming, playing and feeding in the bay below. Makes for a great excuse to stop and catch your breath.

Castell Bach, (“Little Castle”) is an interesting little cove with a Celtic iron age hillfort which sits on the plateau overlooking the cove. Although there is little to see of the “castle” today it is still a great spot to take in the scenery. The beach has an enclosed feel to the rear are high grassy cliffs, while the seaward side is dominated by a rocky knoll, which never quite becomes an island. There are some striking folded strata to be seen on this rock.

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!
