The route runs the whole of St Brides Bay on the Pembrokeshire Coastal Path, and covers some of the most iconic sections of the Pembrokeshire Coast National Park including Ramsay Sound, Solva Harbour Newgale Beach and Broad Haven. Keep your eyes peeled for some of the route's wildlife such as grey seals, gannets and puffins.
Beginning at the foot of the stairs of the old St Davids RNLI station, where ferries leave for Ramsay, follow the Coastal Path to Martin's Haven, where ferries leave for Skomer. An attempt starts with a hand at the foot of the rail of the old RNLI station and finishes when feet hit pebbles on Martin's Haven. Or you may run the other direction.
