Similan Islands No. 8 & No. 9

Similan Islands No. 8 & No. 9: Spectacular Boulders, Exciting Drifts & Pelagic Encounters

Every Friday

Similan Islands No. 8 and No. 9 are where the Similan Islands truly earn their world-class reputation. Home to some of the park’s most famous dive sites, these northern islands combine towering granite boulders, dramatic swim-throughs, sandy channels, vibrant coral reefs, and crystal-clear water to create the classic Similan Islands diving experience.

No two dives around Similan Islands No. 8 and No. 9 feel the same. One site may offer a relaxed reef dive teeming with colourful marine life, while the next delivers an exhilarating drift dive over giant granite formations with schools of fish riding the current. This diversity makes Similan Islands No. 8 and No. 9 a favourite destination for certified divers looking to experience the best diving in the Similan Islands.

The marine life is just as memorable as the scenery. Green turtles are regularly seen gliding along the reef, leopard sharks often rest on sandy patches, and enormous schools of fusiliers, snapper, and glass fish create spectacular underwater displays. During stronger currents, you’ll often witness exciting feeding behaviour as predators move in and baitfish swirl around the reef. It’s these unforgettable encounters, combined with the iconic underwater landscapes, that make Similan Islands No. 8 and No. 9 some of the most rewarding dive sites in Thailand.

Similan National Park Rules

Season: The Similan Islands are closed every year from 16 May to 14 October and open from 15 October to 15 May.
No drones: Drone flights are strictly prohibited.
No single-use plastics: Many Thai National Parks prohibit single-use plastic items (and foam containers). Please avoid bringing disposable plastic/foam packaging into the park.
Reef-safe sunscreen only: Thai National Parks have announced bans on certain chemical sunscreens that are harmful to coral. Please use reef-safe sunscreen or protective clothing instead.
Respect wildlife: Do not touch, chase, or disturb marine life. Never stand on coral or the seabed, and never take shells or coral as souvenirs.
Follow park staff & boat crew instructions: Rules can change depending on conservation measures and conditions. Always follow the guide briefing and any ranger instructions.

New Thailand Diving & Snorkeling Rules

Thailand introduced stricter nationwide standards for diving and snorkeling activities (effective 22 April 2025) to protect coral reefs and improve safety.

Supervision required: Every trip must be accompanied by a certified dive supervisor or assistant.
Life jackets for snorkeling near coral: Life vests must be provided and worn when snorkeling near coral reefs (unless the tourist holds a recognized freediving certificate).
Mandatory briefing: Guests must receive a briefing on laws, safety, and responsible marine practices before activities.
Group ratios: Limits apply to how many guests one supervisor can oversee (different limits for deep diving vs snorkeling/freediving, and for training sessions).
Camera rules: Underwater photography is restricted unless the diver is qualified (e.g., Advanced certification or 40 logged dives) and can show proof if requested.
Reef distance: Divers must stay at least 2 metres above coral heads, and fin control must be demonstrated before approaching coral areas.

To comply with these rules, reminder: we may limit snorkeling approach to reefs, and we may ask guests to leave cameras on board if requirements are not met. Divers are expected to control their buoyancy for their own safety and the safety of the guide, group and environment.

Booking Deadlines

Bookings: latest 18:00 the day before the trip.
