The "poshest" part of Croatia is widely considered to be Hvar Town on the island of Hvar, often dubbed the "St. Tropez of the Adriatic." It is the preferred destination for the international elite, celebrities, and yacht-owners, known for its glamorous nightlife, sophisticated beach clubs like Carpe Diem, and high-end boutique hotels. Another top-tier luxury enclave is Dubrovnik, particularly the Ploče district, which is home to the city’s most exclusive five-star hotels—such as Villa Orsula and Hotel Excelsior—offering private stone beaches and unparalleled views of the Old Town walls. For those seeking "Old World" elegance, the town of Opatija in the north is the historic favorite of Austro-Hungarian royalty, filled with Belle Époque villas and luxury wellness retreats. In the Istrian peninsula, the town of Rovinj has emerged as a chic, romantic escape featuring Michelin-starred dining (like Agli Amici) and designer accommodations. Whether you are chartering a private gulet to explore the hidden coves of the Kornati Islands or dining at the 360° restaurant in Dubrovnik, these areas represent the absolute pinnacle of Croatian luxury, combining Mediterranean charm with world-class service.
