All the details about your upcoming adventure in one place
The Similan Islands (Mu Ko Similan National Park) are world-renowned as one of the top diving and snorkeling destinations on the planet. Located in the Andaman Sea, roughly 85km northwest of Phuket, this archipelago of nine granite islands offers underwater visibility of up to 30 meters. The marine park is strictly protected and only open from mid-October to mid-May, ensuring the coral reefs and marine life—including sea turtles, leopard sharks, and manta rays—remain abundant and undisturbed. Whether you choose a high-speed catamaran for comfort or a private charter for exclusivity, a day trip here promises aquarium-like swimming conditions and breathtaking scenery.
All our partners are licensed to enter Mu Ko Similan National Park and adhere to strict safety and environmental regulations.
We curate tours with high guest satisfaction, prioritizing operators who offer premium speedboats and knowledgeable guides.
Many of our listed tours offer 'early bird' departures to reach iconic spots like Sail Rock before the main crowds arrive.
Secure your spot in this limited-capacity national park immediately, with flexible cancellation policies for peace of mind.

Real experiences from real travelers
The water clarity is unbelievable. We saw three turtles and thousands of fish. The speedboat ride was fast but fun. Highly recommend booking the early tour to beat the crowds.
The islands are paradise, exactly like the photos. The snorkeling at Island 9 was the highlight. Just be prepared that it gets crowded at the main beach. The lunch provided was delicious.
Everything was well organized. The guide spoke good English and Chinese. The pick-up from our Phuket hotel was on time. The Similan Islands are a must-visit if you come to Thailand.
We booked the premium catamaran tour and it was worth every penny. Much smoother ride than the speedboats and better food. Sail Rock view is breathtaking.
Visibility was 30 meters plus. Coral is recovering well. The guides were very professional and safety conscious. A long day but worth it.
