The luxurious Aman Sveti Stefan resort is an 80-acre coastal estate with a beautifully preserved 15th-century island fortress and the 19th-century Villa Milocer set on the mainland of Montenegro. It offers access to the private, picturesque Queen's Beach set in seclusion beside an emerald lagoon, but guests can also choose from three swimming pools and a trio of pink-sand beaches that are among the most beautiful on the Adriatic.
