Sean Fletcher spells out what it is he loves so much about Wales, with his 'seven wonders of Wales' - the mountains, hill farming, heritage, wildlife, castles, food and the coastline. This final wonder is a particular favourite of Sean's, and he's not the only one to think that. So to celebrate its shoreline, Wales has chosen 2018 as its Year of the Sea. From the 870 miles of pathway that run the whole length of the coastline, many Welsh wonders can be seen. Sean journeys along Pembrokeshire's stretch of the Welsh Coastal Path. On the way he flexes his Welsh language skills as he meets people who live and work on the path with tales to tell.
