As its main land, it is noted that most of the visitors will be concentrated on Derawan Island due to these 5 factors:
First, there are more various choices of hotel / homestay - of course with different range of prices too - make this island becomes an excellent choice for either visitors or tour providers while dealing up with their budget. (Hey! look at those bungalows beside, is it too crowded for a 20-minutes-walk-island?)
Second, the electricity is supplied for 24 hours. (Yeay! Hence I can keep charging my phone and stay online all day long! This is the essence of having holiday right, eh?)
Third, Derawan is located only about 15 minutes from nearest Kalimantan land, which is Tanjung Batu. This is the closest island to the main land compared to other, makes every supplies becomes fairly cheaper. (Yeay! ..... well, just yeay :| )
No, I don't own any drone. This image is creditted to my closest friend, and partner, google..
Forth, even though it is only tiny island, however fresh water is abundant here - makes Derawan becomes the most dense island on this regency.
Okay, let's go to the next island! (Hmm, What?! Wait!! You said that there are 5 factors? But this is only 4!! Where is the other one? Hey, answer me!!)
