Riau Islands, Palawan Beach, Great Karimun
Karimun  is a small island offerring a range of tourist activities in the Riau Islands province of Indonesia. It is also the name of a group of islands and regency (kabupaten) to which it belongs.
Karmun is located just off the east coast of Sumatra, guarding the southern entrance of the busy Straits of Malacca. It lies west of Batam and to the southwest of Singapore and is the furthest west of the Riau Islands.
Its proximity to Singapore has made the islands quite affluent and busy. Its main town, Tanjung Balai is a bustling port town with a lot of commerce, boosted by tourists from Singapore and Malaysia, however, it must not be confused with Tanjung Balai in North Sumatra province, a much larger city also known as Tanjung Balai Asahan and an international port. However, like Batam and Bintan, Karimun is also listed as a Free Trade Zone area.
