Ko Tarutao is an island located in the far south of Thailand, off the coast of Satun and near the sea border with Malaysia. It is the largest island in Tarutao Marine National Park, which comprises 51 islands in the Andaman Sea.The name "Tarutao" comes from a local word meaning "old, primitive and mysterious." This name perfectly reflects the island’s appearance, with its lush tropical forests, rugged mountains, crystal clear waters and desolate white beaches.The island’s landscape is dominated by steep mountains covered with dense jungle. Its highest points reach nearly 700 meters in height. The western side of the island is characterized by long sandy beaches and quiet bays, while the eastern coast is more rocky and wild.Ko Tarutao is known for its biodiversity. In addition to a wide variety of tropical plants, the island is home to many species of animals, including monkeys, monitor lizards, sea turtles, and a wide variety of birds. The rich seabed around the island is populated by an extraordinary diversity of marine life, making it a popular destination for snorkeling and diving.Despite its natural beauty, the island has a dark history. During World War II, it was used as a prison camp for political criminals. Many prisoners died from the harsh conditions and disease, and the island became known as the "Alcatraz of Thailand."Today, however, the island is a peaceful and relaxing place. There are no roads or motorized vehicles on the island, and the only way to get around is by foot or bicycle. There are some tourist facilities on the island, including a small resort and visitor center, but in general the island is undeveloped and maintains a very quiet and authentic atmosphere.In summary, Ko Tarutao is a true paradise for nature lovers and those seeking a retreat away from the hustle and bustle of the modern world.
