Similan Islands

หมู่เกาะสิมิลัน

A pristine national park archipelago renowned as one of Thailand's premier diving destinations with world-class coral reefs, granite boulders, and abundant marine life. Accessible primarily through organized diving tours and liveaboards, it offers an unforgettable underwater experience.

Things to do

• Scuba Diving at Elephant Head Reef — Explore one of the most famous dive sites featuring dramatic granite boulders, vibrant coral gardens, and encounters with reef sharks, barracuda, and grouper.
• Snorkeling at Breakfast Bend — A shallow, protected reef area ideal for snorkelers to observe colorful fish, sea turtles, and soft corals without deep diving certification.
• Night Diving Experience — Descend after dark to witness nocturnal marine creatures including octopus, squid, and bioluminescent organisms in their active state.
• Granite Boulder Exploration — Navigate through massive underwater granite formations creating swim-throughs and caves that shelter diverse fish species and create stunning photographic opportunities.
• Manta Ray Spotting — Visit seasonal sites during November to March when manta rays congregate to feed on plankton blooms, offering graceful encounters with these gentle giants.
• Liveaboard Diving Tours — Stay aboard a traditional longtail liveaboard vessel for multi-day expeditions covering multiple islands and exclusive dive sites unreachable from day boats.
• Beach Exploration and Island Trekking — Hike through pristine island interiors with minimal development, observing native flora and panoramic views of the Andaman Sea from elevated viewpoints.

Food to try

• Fresh Grilled Fish — Locally caught snapper, grouper, or barramundi grilled whole with lime, chili, and garlic, typically served on liveaboards or in nearby Phuket ports.
• Tom Yum Seafood Soup — Traditional Thai hot and sour soup made with prawns, squid, and fresh catch from the Andaman Sea, aromatic with lemongrass and galangal.
• Green Curry with Local Fish — Spicy Thai curry prepared with fresh green chilies, coconut milk, and daily-caught fish served on dive vessels between diving sessions.
• Satay and Grilled Seafood Platters — Grilled prawns, squid, and fish skewers served with peanut sauce on liveaboard decks, a staple evening meal after diving.
• Fresh Tropical Fruits — Mango, papaya, pineapple, and dragon fruit sourced from nearby coastal markets, refreshingly served throughout the day on boats.

Local customs & good to know

• Respect Marine Protected Areas — The Similan Islands are a strict national park where collecting shells, corals, or harming wildlife is prohibited; follow all guide instructions and regulations carefully.
• Sea Gypsy (Moken) Awareness — The indigenous Moken people have traditional ties to these waters; show respect for their heritage and avoid intrusive behavior if encounters occur.
• Environmental Consciousness Underwater — Avoid touching corals, use reef-safe sunscreen only, and maintain neutral buoyancy to prevent damaging this fragile ecosystem that depends on conservation.
• Seasonal Accessibility — The islands are closed to tourists from May to October during monsoon season due to rough seas; plan visits between November and April for safe access.
