Check into your hotel. The rest of the day is free for you to explore some of Ljubljana, Slovenia’s capital, with the help of the CosmosGO app. Tonight, meet your Tour Director and travel companions.

Undoubtedly, one of the highlights on this tour is a visit to the Postojna Caves. Take an included underground train ride and a walking tour, marvel at what are possibly Europe’s most extensive and most beautiful caves. Then, cross into Croatia, traveling along the coast to Zadar. Over the centuries, Zadar was ruled by Venetians, Austro/Hungarians, by Italy after WWI, and today it belongs to Croatia. Learn more during the included guided tour.

Drive south to Split. This is the former hometown of Roman Emperor Diocletian, and you can still visit with a Local Guide the remains of his Palace, and Jupiter Temple, a UNESCO World Heritage Site. See more of the lovely Dalmatian Coast before reaching Dubrovnik.

Dubrovnik is the best-preserved Croatian medieval city and the liveliest in Dalmatia. On a guided walking tour, visit the Franciscan Monastery and the Rector’s Palace, where the Local Guide will give you a full commentary, including the history of this beautifully preserved medieval architectural wonder—a popular filming location for TV series and movies, including “The Last Jedi,” “James Bond,” and “Game of Thrones.”

Enjoy a scenic drive into the rugged beauty of the Neretva Valley. Stop in Mostar, where a Local Guide shows you the Turkish House, the Mosque, and the reconstructed 16th-century bridge. The Mostar bridge stood for 427 years, until it was destroyed in 1993 during the Croat-Bosnian war. A project was set in motion to reconstruct it, and the rebuilt bridge was opened in 2004. On to Sarajevo, capital of Bosnia-Herzegovina and certainly the most Turkish-looking city in the Balkans—famous for its mosques, markets, and bazaars. Discover the city with a Local Guide and get acquainted with its architectural highlights, including the Gazi Husrev-Beg Mosque.

Travel north today back into Croatia to visit the country’s famous Plitvice National Park. Enjoy a walk with a Local Guide through the breathtaking scenery of this natural wonder. Its 16 lakes, wooded hills, waterfalls, and cascades make it one of Europe’s best-loved national parks.

Get to know Croatia’s capital, Zagreb, on the included city tour. The city is packed with historic buildings, such as the Gothic-style St. Marcus Church. Continue to Ljubljana, where a Local Guide will share insights to appreciate its imperial beauty even more.
