Located one hour south of Dubrovnik lies the Montenegrin Littoral, a place with incomparable natural beauty and a dizzying array of historical sites. Take a guided day trip and explore this beautiful region, including a stop-over in Kotor, one of the best-preserved medieval towns in the Mediterranean.
You'll also visit the coastal town of Budva with its many beaches and the picturesque town of Sveti Stefan. Its tiny island, which has managed to retain much of its ancient character, has one of the most prestigious and private hotel resorts on the Mediterranean and is a favorite amongst celebrities.
Korcula and Peljesac Peninsula
The finger-like Peljesac Peninsula is home to some of Croatia's most gorgeous beaches. Most people who visit here pass through on their way to Korcula, a scenic island known as the birthplace of Marco Polo.
Take a guided excursion to Korcula and spend the day exploring its eponymously named historic old town and its narrow streets that branch off the spine of the main street like a fish bone. You will also have some free time to visit the medieval walled town of Ston. Its walls were built in the 16th century and are the second longest defensive walls in the world after the Great Wall of China!
The twin towns of Ston and Mali Ston are best known for two things: oysters and the second largest manmade defensive stone wall in the world after the Great Wall of China.
Visit the historic towns on a guided day trip where you can take an opportunity to walk part of the stone wall that helped protect Dubrovnik from the Ottomans and Venetians for centuries. You'll also have the opportunity to learn how to pick and shell your own oysters, followed by a recommendation of which one of Mali Ston's exquisite restaurants to have lunch at.
Take a day trip over the border into Croatia's beautiful neighboring country of Bosnia and Herzegovina for a spectacular visit to the historical town of Mostar. Mostar is, of course, most famous for its medieval arched bridge destroyed in the Balkans conflict of the 1990s following the disintegration of Yugoslavia.
Today the bridge and the surrounding Ottoman mansions have been lovingly reconstructed and you'll get a close-up view of them on your day trip as you wander through the historic center. You'll also stop over at the stunning medieval hamlet of Počitelj where you can climb to the top of the treacherously steep Turkish citadel to be rewarded with a breathtakingly gorgeous view of the Počitelj village and mosque nestled on the luxuriantly green banks of the Neretva River - one of the finest picture-perfect architectural sights in all the Balkans.
Mljet National Park
For those looking to spend more than a couple of days in Dubrovnik, you should try not to miss the opportunity to visit Mljet National Park on Mljet Island.
As Croatia's 8th largest island, Mljet has a lot to offer a day tripper traveling from Dubrovnik by ferry. Located just 15 miles from the city, it offers an unspoiled oasis of lush vegetation, pine forests, swimmable blue-green saltwater lakes encircled by foot- and cycle paths, and an island within island containing a beautiful 12-century monastery church.
Some 12 miles south of Dubrovnik and easily reachable by boat or local bus from central Dubrovnik, Cavtat is a fascinating and cultured destination in itself.
Without Cavtat, there would be no Dubrovnik, for it was inhabitants from this ancient Greek settlement previously named Epidaurum who first populated Dubrovnik.
A day trip to one of the Elafiti islands in this archipelago northwest of Dubrovnik makes an enjoyable escape from the busy summer crowds. The largest three islands – Koločep, Lopud and Šipan – are the only ones that are permanently inhabited and serviced by ferries.
Opt between seeing all three in one day on a 'Three Islands & Fish Picnic' tour or visit at least two of the islands independently using a public catamaran service. All the islands have nice beaches, attractive harbor towns and are peppered with enchanting stone churches and old fortresses.
