An affordable trip to the Mediterranean? Enter Montenegro. Mountains, beaches, and medieval villages are just some of the highlights in this tiny Balkan beauty. As a still emerging destination on the Adriatic, Montenegro is a bargain holiday spot. Kotor's old town is a UNESCO World Heritage site where you can wander cobblestone streets by morning and take a boat to an island church in Perast by afternoon. Trek to the top of the city's fortress for sweeping views over the bay and make sure to indulge in the local seafood (you're on the coast, after all). Once you've had your fill of the city, the mountains and other port villages are calling. Venture to Stari Bar, an archaic Byzantine fortress city, check out Ulcinj, a beachside Albanian-influenced town, and go canyoning or white water rafting in Durmitor National Park, another UNESCO World Heritage Site.
