We found a reference to this in the Michelin Guide to Brittany. Directions sounded a bit vague so I spent some time with Google maps identifying the exact location. This paid off as otherwise we would never have found it as it is unsigned until you are there. It is called Pont Krac’h in Breton.
We approached from the north side of the Aber (river mouth) rather than the south side as recommended by Michelin, as access looked to be better.
Coming from the south on D13 take the first right turn immediately after the bridge across Aber W’rach. At the T junction turn Right and stay on this road ignoring side turns through Prat Pol. Shortly after the road curves to the right. Take the right fork to the small parking area at the end of the road.
It is a pleasant walk down a sunken lane lined with tall trees to the ‘bridge’ across the aber which is tidal here. It is in fact a causeway of large granite slabs with gaps to allow the tide to flow between them. The causeway has seaweed rowing over most of it but it is possible to cross with care and a footpath leads up from the far side.
There seems to be some confusion as to the age of the causeway. Michelin describes it as a Gallo-Roman stepping stones. Other sources believe it to 10thC. Either way, it would have been an important crossing point over the Aber.
Like many other old bridges there is a legend attached to it. A local miller was fed up of having to make the long detour around the Aber. He made an pact with the devil who would build the bridge in exchange for the first soul that crossed it. Next morning the bridge was built. The miller loaded a sack of flour containing his cat. When he reached the bridge he pretended to be tired, put down the sack and released the cat. Apparently drunk peasants going home at night would fall off the bridge and drown – the devil’s revenge.
Time your visit for low tide to see the causeway at it’s best. Sea levels have risen 2m over the last 2000 years and the causeway is covered at high tide.
On the way back stop to admire Chapelle St Paul in Prat Pol. It is a small stone building set on a grassy bank with a small fountain. It is dedicated to St Pol Aurelien who was a Celtic Missionary and one of the seven founding saints of Brittany, who stopped here on his journeys. One legend tells how he decapitated a dragon whose head bounced three times before being buried under a cross at Pont Crac’h.
