10-Day British Isles Round-Trip London: England, Ireland & Scotland

Southampton, England's storied ocean liner capital on the southern coast, carries an indelible maritime identity — this is the port from which the Titanic departed and from which the Queen Mary 2 still sails in grandeur today. The medieval Bargate and City Walls speak to a history stretching back to Roman times, while the SeaCity Museum tells the story of the great liners with moving intimacy. Day excursions reach Winchester's magnificent cathedral, the stately rooms of Beaulieu, and the primeval wilderness of the New Forest — where ancient ponies still roam freely. Spring and summer offer the most pleasant conditions for exploring the region.

San Juan, Puerto Rico's radiant colonial capital, is one of the Americas' most compellingly layered cities — a place where the sixteenth-century fortresses of El Morro and San Cristóbal stand sentinel over streets of painted townhouses and flowering balconies. The cobblestoned lanes of Old San Juan pulse with world-class rum bars, ceviche stands, and rooftop restaurants serving the island's vibrant cocina criolla. La Fortaleza, the oldest executive mansion in the Western Hemisphere still in use, anchors the historic district. Florecer, the district's famed bioluminescent bay, glows emerald after dark. January through April offers the most idyllic conditions.

Invergordon is a charming port town in the Scottish Highlands, known for its rich history and scenic beauty. Must-do experiences include exploring the historic Battlefield of Culloden and savoring traditional dishes like haggis and cranachan. The best season to visit is during the summer months when local festivals and events bring the vibrant culture to life.

Liverpool, an historic port city, is renowned for its unique blend of vibrant culture and rich maritime heritage. Must-do experiences include sampling authentic Scouse and exploring the Three Graces along the waterfront. The best season to visit is during the mild summer months, when festivals and events enliven the city’s atmosphere.

Belfast, Northern Ireland’s capital, is a vibrant port city renowned for its rich shipbuilding heritage, highlighted by the Titanic Belfast museum. Must-do experiences include exploring the historic Cathedral Quarter and tasting traditional dishes like Irish stew and soda bread at St. George's Market. The best season to visit is during the spring and summer when the city comes alive with festivals and outdoor events.

Dublin is Europe's most literary capital, home to four Nobel laureates in literature, the extraordinary Book of Kells, and Georgian architecture rivaling any on the continent. Visit May through September via Holland America Line or Windstar for Trinity College's Long Room, the definitive Guinness pint at St. James's Gate, and the spontaneous pub conversations that make this city one of the world's most immediately welcoming.

Waterford is Ireland's oldest city, founded by Vikings in 914 AD, featuring a magnificently restored medieval quarter, the world-famous House of Waterford Crystal, and three museums housing the finest medieval collection in the country. Must-dos include Reginald's Tower, crystal-making demonstrations, and tasting the city's unique blaa bread rolls. May through September offers the warmest weather, with September often bringing surprise Indian summer days.

Portland is the wind-sculpted limestone peninsula that supplied the stone for St. Paul's Cathedral and Buckingham Palace, connected to Dorset's Jurassic Coast by the extraordinary Chesil Beach. Visit May through September via Seabourn or Ponant for quarry sculpture trails, Portland Bill's lighthouse panoramas, and access to England's first natural UNESCO World Heritage Site — a coastline of 185 million years of geological drama.
