The largest of the northern Dalmatian islands, Dugi Otok – which translates as Long Island – is… erm, long. 45km long to be precise, with a measly width of just 1 – 4km. Characterised by sheer cliffs and sandy beaches (the most famed is Sakuran), it’s a sliver of dramatic natural beauty, with its south-eastern quarter declared a National Park and its Telascica Bay generally agreed to be one of the most stunning Adriatic beaches. You can get there by fast boats from the mainland, and spend several days following trekking and cycling trails, scuba diving, climbing – or simply admiring the view from the comfort of a local restaurant.
