Natuna Besar
Natuna Besar (or Ranai) is the largest and northernmost of the islands and also one of the northernmost points in Indonesia. Here we can find lovely corral reefs and a large variety of fish. The population is relatively small, but some people have been moved here by the government from other islands in Indonesia and grow products like peanuts and peas. Mount Ranai, the highest mountain in Natuna archipelago at 1.035 m, is located on this island. There are some great areas for diving here, the waters of the South China Sea around the island can offer an unique underwater world, the coral is normally found within five to ten meters below sea level and 50 to 750 meters from the shore. Smaller islands like Senoa to the northeast can also offer white beaches and coral reefs, Panjang to the northwest is known for the protected green turtle, and can be reached by boat from Natuna Besar in 30 minutes. Totally there are about 20 small islands surrounding Natuna Besar.
South Natuna is located between Natuna Besar and the Kalimantan mainland, the main islands here are Serasan, Panjang and Subi. The islands have a strong surf and impressive scenery
