With some of the largest sand dunes in Britain, NatureScot's Forvie National Nature Reserve is one of Scotland's most dramatic stretches of coast. The mud flats of the Ythan Estuary provide a fast food refueling stop for many passing birds and the mouth of the estuary is a year-round haul out for seals. The wind and the tide are in charge here, and it's a great place to blow the cobwebs away with the chance of seeing some spectacular wildlife.
