Bratislava, Slovakia’s capital, sits along the Danube River at the crossroads of Central Europe. It's the only capital in the world bordering Austria and Hungary, which makes it an easy stop on many European itineraries. Yet Bratislava is more than a waypoint; it offers a compact city center filled with centuries of history. The Old Town’s cobbled lanes lead past Gothic cathedrals, Baroque palaces, and buildings once used by Habsburg royalty.

Rorvik is a busy fishing community on the eastern side of the Vikna archipelago. Outdoor activities abound in this maritime region, including kayaking, canoeing, fishing and diving. Several museums offer a look at Rorvik's culture and history, and wildlife enthusiasts will find a myriad of bird and fish species to observe.

Passau sits on the confluence of the Danube, the Inn and the Ilz, so it is fitting that it is known as "the Dreiflüssestadt", which means the “City of Three Rivers.” The historical center offers a cathedral, churches and museums to explore, and the embankment is perfect for a romantic stroll.

El Chaltén sits at the edge of Los Glaciares National Park in Argentina’s Patagonia region, framed by the iconic peaks of Cerro Fitz Roy and Cerro Torre. Its remote location beside the Río de las Vueltas makes it a gateway to dramatic landscapes of granite spires, glacial streams and wide steppe plains.

Nestled along the south bank of the Danube, this historical Austrian city bursts with charm. A favorite stop on European river cruises, the city's most famous attraction is Melk Abbey, which dates back to the 11th century. The original Benedictine structure was lost to fires and foreign invasion, then rebuilt during the 18th century in lavish Baroque style, including a library and inner church covered in magnificent frescoes and gilded fixtures.
