Tarutao Island (Ko Tarutao)
Although it is the largest island of Thailand’s Tarutao National Marine Park, Ko Tarutao, is considered one of the most primitive and untouched islands in the Andaman Sea. With its mountainous terrain and thick jungles, the population of monkeys and other fauna far outnumber the humans on Ko Tarutao. However, for travelers willing to forego luxury, the island’s pristine beaches are second to none.
