Similan Islands Holidays

Floating in the Andaman Sea 100 kilometers northwest of Phuket, the Similan Islands stand as Thailand's hidden marine jewel. This archipelago of eleven islands comprises one of Southeast Asia's most pristine natural environments, captivating visitors with extraordinary beauty both above and below the surface.

Designated as Thailand's 28th National Park in 1982, the Similans (from the Malay word "sembilan" meaning nine) showcase nature in its purest form. The islands feature a striking contrast: eastern shores with powdery white beaches that glow against turquoise waters, while western coastlines display dramatic granite boulder formations that seemingly defy gravity—continuing underwater to create fascinating swim-throughs and caverns.

The marine ecosystem is breathtaking, hosting over 500 coral species and 650 fish species. Divers regularly encounter manta rays, whale sharks, sea turtles, and vibrant reef fish in waters with visibility often exceeding 30 meters.

Open only from October to May to protect its fragile ecosystem, visitors can stay in basic national park accommodations or on liveaboard vessels. Beyond diving, the islands offer pristine beaches, hiking trails through tropical forests, and panoramic viewpoints.

Conservation efforts include visitor restrictions and bans on harmful products. For responsible travelers seeking Thailand's most spectacular underwater experience, the Similans deliver unforgettable natural wonder.
