Riau Islands Province (Indonesian: Provinsi Kepulauan Riau, acronym: Kepri) is a province of Indonesia. It comprises the principal group of the Riau Archipelago, together with other island groups to the south, east and northeast. In Indonesian, Riau Islands and Riau Archipelago are synonymous and are distinguished by the word for province, "Provinsi". Originally part of the Riau province, the Riau Islands were split off as a separate province in July 2004.

There are around 3,200 islands in the province, which has its capital at Tanjung Pinang in the south of Bintan Island. The province includes the Lingga Islands to the south of the main Riau Archipelago, while to the northeast lies the Tudjuh Archipelago, between Borneo and mainland Malaysia; the Tudjuh Archipelago consists of four distinct groups — the Anambas Islands, Natuna Islands, Tambelan islands and Badas Islands — which were attached to the new province, though not geographically part of the Riau Archipelago. The 2010 census count was 1,685,698,[3] however, the province lists the March 2013 population at 1,960,789.[1]

Tambelan archipelago is a group of islands off the west coast of West Kalimantan, (Borneo), Indonesia, just north of the equator. Geographically they are part of the Tudjuh Archipelago, and administratively part of the Riau Islands Province. Major islands include Big Tambelan (Tambelan Besar), Mendarik, Uwi, Benua, and Pejantan.

Tambelan Archipelago or Kepulauan Tambelan is a group of islands (more than 40 islands and islets) west of the coast of Kalimantan (Borneo), Indonesia, just north of Equator. Geographically part of the Archipelago or Kepulauan Tudjuh Tudjuh (Badas Islands Tambelan, Natuna and Anambas) and administratively part of the province of Riau islands. 

The archipelago is located between latitude 0 ° 40 'N and 1 21' N and the meridians 106 ° 21 'E and 107 ° 59' E, amid the Natuna Sea and bordered by the South China Sea. 

The largest islands are Tambelan Besar (Great Tambelan) Uwi (Oewi) and Benua (Benoea). The district Tambelan (belonging to Bintan regency) consists of 7 villages. Because of its isolation, much of the population has migrated to large Indonesian cities (Pontianak, Jakarta or Tanjungpinang). The capital and most populous district is Tambelan Kukup (Kukup or also called Kampung Batu Lepu) on the island of Besar Tambelan housing four other villages. The Pinang and Mentebung islands have a village each. The total population (2006) is 4,514 people. Almost 90% of the population is Muslim and ethnic composition is predominantly Malaysian (Malay, Chinese, Javanese, Bugis, buton, flowers and Batak). The total area of the islands is about 357,000 hectares. 

The islands are remote from the usual loss of maritime traffic. The island to the east of the archipelago (Tokong Mengirang or White Rock) is 60 miles WNW of Tanjung Batubelat (0 ° 49 'N and 108 ° 51' E), the western tip of Borneo. 

Although, in general, the channels between islands are clean and deep, there are several banks, and reefs scattered throughout the area with which to sail the waters of the archipelago is essential to have detailed charts stones. 

The maritime climate is tropical with an average temperature of 29 to 30 ° C, with a minimum of 28.9 to a high of 30.26. 

The surface sea temperature varies between 9.2 and 30.3 degrees Celsius. 

The mangrove is present in almost all the islands. It is estimated that there are nearly 15,000 square kilometers of living coral in the archipelago. Despite irresponsible fishing which has been carried out for many years (dynamite, poison, diving suits, etc.) makes the fish wealth is still considerable. In August 2007 a ​​Marine Protected Area of 480,000 hectares where you can practice only sustainable artisanal fisheries and aquatic tourism was established. Sea turtles used annually beaches of the islands to spawn. 

In 2007, fishing accounted for almost 84% of the productive activities of the archipelago. 

Pulau Tambelan is the largest and most important island of the archipelago located southeast of the NE group. On the north side of the island three prominent peaks are recorded: Bini (396 m) to W, Kotit (291 m) at a mile east of Bini and Puter Jala (290 m) conical and 1.5 miles ESE Koti. 

The entrance to the bay Tambelan (Teluk Tambelan) is relatively easy. Some of the reefs are marked with beacons. During the NE monsoon season you can anchor at the entrance to the bay with 10 fathoms. During the SW monsoon season should fund further inland NW of Tandjoeng (Punta) SADAP at depths between 7 and 9 fathoms. In the latter case, it is necessary to proceed with caution or local aid. 

It is accessible to the population in the bottom of the bay through a canal boat signposted. 0.4 miles SW of Kampung Batu Lepu or Kukup is a wooden jetty of 160 m in length with 0.5 meters deep. 

It seems that the first inhabitants of the archipelago (circa 1000) came from China. Over the years a small realm based on the population in the territory was established. 

During the seventeenth century the islands changed hands several times during the wars between the sultanates of Johor and Aceh and the interventions of the Portuguese and Dutch for control of the Strait of Malacca, Sumatra, Malaysia and Borneo. 

In 1824 the islands were finally under control of the Dutch. Between 1942 and 1945, the islands were occupied by the Japanese. With the proclamation of the independence of Indonesia, the islands became part of this country. 

Tourism is in its infancy, but progressively increasing due to relatively unspoiled landscape. The major attractions are the turtle watching, diving, beaches and gastronomy. There are also historical sites such as the tomb of Sultan Abdullah Muayat Syah of Johor. No airports and the only access to the islands is by sea from Bintan.
