A good place to begin your exploration of this maritime city would be Plymouth Hoe, a scenic promenade offering panoramic views of the sound. Climb the iconic lighthouse known as Smeaton’s Tower for a perspective on the scenery from above before exploring the nearby Royal Citadel, a 17th-century fortress. A pleasant stroll takes you to the Barbican district, Plymouth’s historic quarter, where you’ll find charming shops, art galleries and seafood restaurants as well as the Mayflower Steps commemorating the departure of the Pilgrims for the New World in 1620.

Ireland’s oldest city, Waterford is a charming destination known for its rich Viking heritage, picturesque scenery and unique cultural attractions. Start at the Viking Triangle, a historic area where narrow cobblestone streets and centuries-old buildings transport you back in time. Here you’ll find the Waterford Treasures, a group of adjacent museums that showcase everything from the 18th-century Bishop’s Palace to the 10th-century Reginald’s Tower, filled with Viking artifacts.
