The romantic Douro River winds through northern Portugal, creating a landscape of sculpted hills and terraced vineyards. Begin your journey exploring the Spanish cities of Madrid and Salamanca. Then embark on a 7-night cruise aboard the Ama Vida from picturesque, medieval Barca d’Alva to Porto, a delightful mosaic of scarlet and gold architecture. Taste locally produced olives, almonds, breads and cheeses, and of course, port–the famous sweet, fortified wine the area is known for. Along the way, you’ll learn about the Alto Douro’s winemaking history, witness beautiful Portuguese tile artwork and explore charming villages . Madrid and Lisbon extensions are available.

Venturing to Antarctica is an expedition like no other–a chance to explore wonderlands of sculpted snow and ice where whales swim, penguins flock and albatross soar. Cruise the Drake Passage one way, and then bypass the Drake on the way back on a 2-hour flight from Antarctica. Travel with a team of experts aboard the National Geographic Explorer, the definitive expedition ship. Venture into channels and coves framed by towering peaks. Watch for whales off the bow; Zodiac cruise around enormous icebergs; and hike or kayak. Plus, get top shots with the help of a National Geographic Photography Expert.
