In the middle of the Andaman Sea lie the picturesque Similan Islands, a group of eleven islands that embody the true essence of natural beauty and vibrant marine life. These islands are an unspoiled paradise where time seems to have stopped, allowing visitors to fully enjoy the tranquility and stunning topographical highlights.

Each island in the archipelago is unique, offering a mix of natural beauty and rich biodiversity. From Ko Hu Yong, known for its long white beach, to Ko Similan, the largest island that offers an abundance of activities, visitors get their money’s worth. The islands are numbered from 1 to 11, each with its own name and characteristics.

Discovering the Similan Islands

Geography and overview

The Similan Islands are located 70 kilometers off the coast of Phang Nga Province. These islands are known for their pristine waters, pristine white sand and dense tropical forests. Although the term “Similan” is derived from the Yawi word for nine, two additional islands were added to the national park in 1998.

Impact of tourism and conservation efforts

Despite their beauty, the islands are heavily impacted by tourism, with overcrowding being a major problem. To mitigate this, park authorities have limited the daily number of visitors to 3,325. Ko Tachai in particular has been closed since 2016 to protect its fragile ecosystem.

Wildlife: a dive into the underwater wonderland

The Similan Islands are home to a variety of marine life, including manta rays, whale sharks and several species of sea turtles. The islands are also home to a vibrant bird population, with over 120 species reported, including some rare birds found only in this region. Unfortunately, the islands were hit by massive coral bleaching in 1998 and 2010, but the corals are on the mend and promise a rich underwater experience for visitors.
