15 Night Spain & Portugal Transatlantic

Discover Southampton’s maritime history at the SeaCity Museum or see impressive works in the city’s art gallery. Jane Austen used to walk Southampton’s city walls and you can too, stopping at the Tudor House Museum along the way. Go all nostalgic over vintage cars at the National Motor Museum at Beaulieu or see King Arthur’s fabled Round Table at nearby Winchester, the ancient capital of England.

The sun will shine upon you as you enter the harbor of Vigo, the largest city in Spain's autonomous Galicia region. Start your adventure by ascending the Castro Fortress — you can take in views of the city and the lushly forested mountains around it from these granite-walled 17th-century fortifications. Then, learn up about the region at one of Vigo's excellent museums: Museo do Mar Galicia features exhibits on the local oceanography and ecosystems, while the Vigo Museum of Contemporary Art hosts a changing lineup of participatory workshops and installations by innovative artists working today. Later, stretch your legs on the GR-53, a 25-mile path along the coastline and low mountain peaks around the city, or relax by the blue waters of Cies Beach.

Lisbon is a quintessential European city, full of natural beauty, historic architecture and culinary pleasures — not to mention one of the best climates anywhere on the planet. To get to know Portugal's capital, walk between the captivating miradouros — terrace viewpoints that are scattered on the hilltops, offering stunning vistas from the sea to the castles and beyond. Watch as the light peeks through the clouds and shines down on The City of Seven Hills during your cruise to Lisbon. If you're a history buff, head to Belem or nearby Sintra to explore UNESCO World Heritage Sites like the Jeronimos Monastery and Quinta da Regalaira.

Portugal's Madeira island is a natural paradise. The lush mountains, brilliant flower gardens and jagged cliffs offer the perfect backdrop for an adventure-filled holiday. Break a sweat hiking one of the levandas, or cool off with a dip in the crystal-clear blue waters. Or indulge in some local cuisine, like grilled mussels or espetada, Madeira's answer to the grilled beef kebab.

Grab a Texas-style breakfast in the historic Strand District. Then explore Galveston’s illustrious history on a scenic stroll past well-preserved Victorian mansions. Cruise from Galveston and dig a little deeper at one of the many local museums, where you’ll discover oil industry exhibits, a restored 1877 tall ship, and historic Texas artifacts.
