While in Dingle, make sure you check out Conor Pass, Slea Head Drive (which is part of the Wild Atlantic Way), Dunquin Pier (pictured), and Inch Beach. And if the weather permits, go surfing or kayaking on Dingle's beautiful blue waters.
For food, definitely grab ice cream from Murphy's, enjoy fresh seafood at Out of the Blue, grab your morning coffee from Bean in Dingle, and enjoy a few pints of Guinness or cider at Dick Macks or Foxy John's.
