Bushmills

Bushmills takes 1 day to see: the Old Bushmills Distillery, the world's oldest licensed whiskey distillery (1608), with tour and tasting included, and its closeness to the Giant's Causeway (15 minutes by car) are the main reason to visit. April-September is best. It's inexpensive by British standards. It's the classic starting point for combining the basalt causeway with an afternoon of Irish whiskey, and several «Game of Thrones» coastal scenes were filmed on the neighboring cliffs.
