Design your own custom group educational tour to other countries: For example, Central Europe is comprised of Austria, Germany, Switzerland, Czech Republic, Poland, Hungary, Slovakia, Slovenia and tiny Liechtenstein, Central Europe offers an overwhelming mix of significant historical sites, grand architecture and old world charm. Here you can tour Salzburg, the city of Mozart; explore both sides of the once-divided German capital of Berlin; marvel at Trümmelbach Falls in Switzerland’s Lauterbrunnen Valley; and cross the famed 14th century Charles Bridge in Prague. You’ll find cities that were largely spared from wartime destruction, such as Kraków, Geneva and Prague, and cities that rebuilt and redefined themselves in the 20th century, such as Berlin and Warsaw. The magnificent castles of Central Europe, including imposing Hohensalzburg, hilltop Spiš and lakeside Chillon, capture the imagination and transport visitors to an era of kings, nobles and knights. There are plenty of off-the-beaten-path treasures to discover in this region, where serene lakes, fresh alpine air, unhurried rivers and quaint medieval towns defy the passage of time.
