Today leans into rural Ireland with a visit to Knightstown on Valentia Island. If you want to stretch your legs, hike toward Valentia Island Lighthouse, which has helped mark this coastline since the 19th century. Another option is searching for the island's tetrapod footprints, believed to show evidence of some of the earliest creatures to move from water onto land, roughly 385 million years ago. Later, cruise around the Skellig Islands, where steep rocky forms, early Christian monastic remains and seabird colonies create one of Ireland's most unforgettable coastal scenes. Watch for puffins, gannets and guillemots, and bring binoculars if you have them.
