Move over, Croatia. Long overshadowed by its neighbor to the northwest, Montenegro is ready for the spotlight. The ancient city of Kotor is already attracting plenty of visitors, like the celebrities vacationing at luxurious boutique hotel Forza Terra, just outside the medieval walls, not to mention the hundreds of thousands of cruisers who’ve arrived with companies like Viking, Celebrity, and Princess. The swank marina Porto Montenegro is thriving in the formerly sleepy coastal town of Tivat, and the complex’s Regent hotel unveiled an expansion in 2017. Nearby, luxury development Luštica Bay is slated to open this summer, with plans for villas, a golf course, and a five-star Chedi hotel. Further west on the Bay of Kotor’s jagged coastline is the site of the country’s most anticipated arrival, the One&Only Portonovi, which will be the brand’s first European outpost when it opens this summer. Plans for the resort, situated on a 60-acre site overlooking the Adriatic, include 140 villas and residences, a tennis club, and a spa. —Meredith Bethune
