Head south form Dubrovnik to explore a relatively untrammeled swath of the Balkans and southern Dalmatia on this guided day trip from Dubrovnik. Cross the border into Montenegro (don't forget your passport!) and then explore Kotor, smack in the center of a dramatic fjord and then head to the walled seaside town of Budva, a combination of history, culture and beachy fun. For something a little more sedate, linger for a while in the charming islet town of Perast. On the drive back to Dubrovnik, drink in the views of the shimmering Adriatic Sea.
