Pag is a Croatian island in the northern Adriatic Sea. It is the fifth-largest island of the Croatian coast, and the one with the longest coastline.
In the 2011 census, the population of the island was 9,059. There are two towns on the island, Pag and Novalja, as well as many smaller villages and tourist places. Pag is the only Croatian island that is administratively divided between two counties. Its northern part belongs to Lika-Senj County, while the central and southern parts belong to Zadar County.
The island is renowned for its cheese and lace.
Pag belongs to the north Dalmatian archipelago and it extends northwest-southeast along the coast, forming the Velebit channel. The island has an area of 284.56 square kilometres (109.87 sq mi) and the coastline is 269.2 kilometres (167.27 mi).It is around 60 kilometres (37 miles) long (from northwest to southeast), and between 2 and 10 kilometres (1.2 and 6.2 miles) wide.
The southwestern coast of the island is low (including the Pag Bay with the large Caska cove), and the northwestern is steep and high (including Stara Novalja Bay). Most of the island is rocky; smaller areas are covered with Mediterranean shrubs. The southeast of the island contains karst lakes Velo Blato and Malo Blato. The island's highest peak, at 349 metres (1,145 feet), is Sveti Vid (St. Vitus).
Grapes (the authentic žutica), vegetables and fruit are grown in the valleys and fields. The northern area of the Lun peninsula is mostly under olive groves. Most communities on the island are connected by a road. A 300 m (980 ft)-long arch bridge connects the southern part of the island to the mainland. The Prizna–Žigljen ferry connects the northern part of the island to the mainland. The island has two towns, Pag and Novalja, and many smaller villages and communities, including Lun, Stara Novalja, Gajac, Kolan, Mandre, Šimuni, Metajna, Dinjiška, Vlašići, Povljana and others.
Unusually, the island is divided between two counties, with Novalja, Stara Novalja, Lun and Metajna being part of the northern Lika-Senj County, and the remainder of the island south of an isthmus at Gajac, including the town of Pag, being part of the southern Zadar County.
The first Croatian wind farm was constructed on Pag island, just northeast of Pag town. The 5.95 MW "Vjetroelektrana Ravna 1" wind farm is composed of seven Vestas V52 wind turbines and has operated since 2004.
Throughout its history, Pag has been connected with salt production, a traditional activity that has been practiced for more than a thousand years. While the earliest historical records of salt production on the island date to 999, it is believed salt was produced on Pag in Roman times. The origin of the town of Pag is connected with the exploitation of natural suitably shallow coves within the closed bay (the so-called Valle di Pago) for salt manufacturing.
