Dugi Otok ("Long Island") is located 10 miles south-west of the city of Zadar, on the Croatian mainland. Its south-eastern tip is only a mile north of Kornat Island. Dugi Otok in this sense is the northern gateway to the archipelago and national park of Kornati.
Most of the west coast of the island is steep and rocky, so the main settlements and anchorages suitable for yachts are located along its north-eastern side, facing the neighboring islands of Ugljan and Pasman.
The bay of Luka Soliscica in the north-west of the island has several sheltered yacht anchorages, as well as the yacht marina Veli Rat. In the south-eastern part of the island there is Luka Telascica bay with many anchorages along the entire length of the bay and at the islet Katina at the entrance of the bay.
The main settlement of the island, Sali, is located four miles north-west of the entrance to Luka Telascica Bay. Further to the north-west along this coast, there are small coves suitable for visiting by yachts. There are U. Triluke, Zmanscica, Luka, Savar, Brbinj, U. Lucina, U. Dumboka and Bozava.
The island does not have such fanciful Venetian architecture as on other Croatian islands and is therefore much quieter during the summer months.
The island has no natural sources of water and, so it is supplied with water from the mainland during the summer,.
The most popular among yachtsmen is the bay Luka Telascica, which included in the Telascica Nature Park.
