Although the world has discovered Croatia and its idyllic shores, neighboring Montenegro, a land of untouched white sands and time-capsule medieval villages, is still largely a well-kept secret. It wasn't always this way: the country once drew Hollywood luminaries like Sophia Loren and Richard Burton to its 183-mile Adriatic Coast. But the Iron Curtain and conflicts following the breakup of Yugoslavia kept many visitors at bay. Today, foreign tourism is on the rise again, up 50 percent in 2005. Last May, Jat Airways launched a direct flight from London, and a tunnel has just been completed that takes drivers from the sleepy capital of Podgorica through the mountains to the coast. Butterfield & Robinson recently added Montenegro to a yacht-based trip in the region, and Amanresorts has plans to restore Sveti Stefan—a peninsula village of 15th-century cobblestoned streets set beside crescent-shaped beaches—to its former glamour. The country's wine region is starting to turn out good Cabernets, and at a growing list of top-shelf restaurants, small-batch vintages are paired with local specialties such as fresh mussels, broiled lobsters, and organic vegetables. So plan a trip soon—before this Riviera has prices on a par with St.-Tropez's. Butterfield & Robinson 800/ 678-1147;; 10-day trips for two from $18,000. Jat Airways Tourism Montenegro
