Daman and Diu are the two tiny union territories which were the Portuguese enclaves. Geographically, Daman and Diu are the part of the state of Gujarat and connected to the mainland of Gujarat by a causeway. Diu is a tiny island in the Arabian Sea, about 11 kms. long and 3 kms. wide, separated from the coast by a narrow channel running through the swamp. It is very difficult to reach here so one has to travel through the town of UNA. This beautiful island has excellent golden beaches, bazaar and huge Portuguese fort. Gujarati, Hindi, English and Portuguese are the main languages which are spoken in Diu. The best time to visit Diu is from September to May.

Diu has a very long and glorious history that stretches back into legends and mythology. It was believed that Pandava brothers of the Mahabharata spent a part of their fourteen years exile in Diu. According to the legends, Diu was once ruled by the great king Jallandhar who was a demon and was killed by the Lord Vishnu with his Sudarshan Chakra. Diu was the first settlement in India of the Parsis who came from Persia in the 7th century. Diu was also ruled by the Mauryans during 320-322 BC and was the main trade center on the Saurashtra Coast. When the Mughal emperor Humayun attacked the Sultan of Gujarat, the Gujarat Sultan entered into a treaty with the Portuguese in 1535 for their help against him. Diu was also rewarded to the Portuguese governor Nuno De Cunha, who constructed a fort in Diu and raised his arsenal. Governor Joao de Castro finally seized Diu in 1546 and it remained a Portuguese enclave till its liberation in 1961 along with Daman and Goa. 

The major tourist attractions in Diu are the Diu Fort, St. Paul's Church, Jallandhar Shrine, Gangeshwar Temple, Diu Museum and Nagoa Beach. Diu Fort is an expansive and imposing structure, situated on the coast of the island. It was constructed between 1535 and 1541 AD and offers a magnificent view of the sea. St. Paul's Church is dedicated to the Lady of Immaculate Conception and built during the 17th century. Diu museum houses wooden carvings, statues, idols, shadow clocks and other important artifacts collected from various sites. Nagoa beach is very beautiful beach, in the shape of a horse shoe.

A grand festival of culture and sporting activities is held for 5 days from 19 to 23 December every year to commemorate Diu's Liberation Day. In this festival various folk performers and traditional craftsmen expose their talents in order to keep the heritage of Diu alive.

Diu has excellent all weather road links with the major cities of Gujarat like Ahmedabad, Bhavnagar, Rajkot and Baroda. The nearest railway station is located at Veraval, which is about 50 kms away.
