Koh Similan Island 8: Sailing Rock, Donald Duck Bay and the Viewpoint

Koh Similan, Island 8, is the largest and most photographed island in the original Similan chain.

Its granite boulders, white sand and bright water create the classic landscape seen in travel photographs. The best-known landmark is Sailing Rock, the huge balanced-looking boulder above the bay.

Why is it called Island 8?

The original Similan chain is numbered from south to north. Koh Similan is number 8, immediately south of Island 9, Koh Bangu.

You may see different English spellings, but Koh Similan and Island 8 refer to the same island.

Sailing Rock

Sailing Rock is a natural granite formation, not a constructed monument. Weathering has shaped the island’s enormous boulders into unusual forms above and below the water.

It is the landmark most visitors recognise and the visual symbol used across many Similan tours.

Can I climb to the viewpoint?

The standard day trip normally offers an optional viewpoint visit when the route is open.

The path is short but not an ordinary pavement. Expect:

• Uneven steps
• Narrow sections
• Granite boulders
• Handrails or ropes in places
• Heat and humidity
• Possible queues

The local photograph of the route includes a sign indicating approximately 150 metres, but distance alone does not describe the difficulty. A short steep route can be harder than a longer level walk.

Wear secure footwear. Keep both hands available and do not carry a loose drink, phone and bag while climbing.

Who should skip the climb?

Enjoy the beach instead if you have:

• Knee, hip, back or balance problems
• Difficulty with steep steps
• Strong fear of heights
• Footwear without grip
• Heat-related concerns
• Any doubt after seeing the actual route

The guide or park ranger can close or restrict the route because of rain, crowding or safety. The viewpoint is never more important than a safe return to the boat.

What is the view like?

From the permitted upper area, visitors can look across the bay, forest, granite shoreline and different shades of Andaman Sea.

The water colour changes with sun, cloud, depth and sea conditions. The colours and conditions you see will vary naturally during your visit.

Donald Duck Bay

The bay around the famous rocks is widely known as Donald Duck Bay because some formations are said to resemble the cartoon character’s head.

Names and translations vary between maps, but the practical visitor experience is:

• White sand
• Granite boulders
• Swimming or beach time in the permitted area
• Access toward Sailing Rock when open

The beach can be busy. Keep the guide’s flag, boat number or meeting point in mind.

Is Island 8 a snorkelling site?

The waters around Koh Similan include important reefs and dive sites, but the standard day-trip programme normally treats Island 8 mainly as a beach and viewpoint stop.

Guided snorkelling may take place at other islands chosen for safer entry and reef conditions. Do not assume you can snorkel independently from any beach.

Dive sites near Island 8

The Island 8 area is associated with recognised scuba sites. Elephant Head Rock, also called Hin Pusa, lies roughly one kilometre south-west of Island 8 and is known for large granite formations, passages and potentially strong currents.

This is a scuba-diving site, not part of the normal beach-viewpoint activity. Divers need the correct certification, recent experience and dive-team assessment.

No animal encounter is guaranteed at any dive site.

How long will the stop last?

The current standard itinerary schedules Island 8 as the final main island stop before the return crossing. Exact time depends on the day.

If you want to climb:

• Listen to the guide’s deadline.
• Join the route promptly.
• Allow time to come down carefully.
• Do not separate from the group to search for another path.

Responsible visit

• Stay on permitted routes.
• Do not climb closed boulders.
• Do not carve or mark rocks.
• Do not feed wildlife.
• Take all belongings and litter with you.
• Do not remove sand, shells, plants or stones.
• Respect rangers managing queues and closures.

Is Island 8 guaranteed?

Island 8 is a normal part of the current standard programme, but any stop may change because of weather, tide, safety, park direction or operational conditions.
