Natuna island is one of the prettiest islands in Indonesia, located in the northern part of the Karimata Strait within the Riau Islands province. It has beautiful beaches with white sand and green water, as well as many large stones along the coastline similar to Bangka Belitung, but sees fewer tourists. The island offers opportunities for swimming, diving, and photographing the scenic views, including from atop the large stones after climbing them, with the stones being among the highest ones in Indonesia.
