Similan Islands Snorkeling Tour By Speed Catamaran From Phuket

The best part of this Similan Islands day trip is the sheer variety packed into one long day: coral snorkeling, quiet beaches, a Thai buffet, and the famous Sailing Rock viewpoint. The speed catamaran cuts across the Andaman Sea, but the route still involves a long road transfer before you reach the pier.

I like the easy all-in setup, with hotel pickup, equipment, lunch, fruit, and accident insurance included. I also like the chance to visit several islands instead of seeing only one beach. The drawback is time: with up to 70 people and many stops, snorkeling and island visits can feel rushed, and the coral is not as healthy as it once was.

Key points

• Early start from Phuket: Pickup begins around 6:00 a.m., and the full day lasts about 11 to 12 hours including road transfers.
• Thap Lamu departure: You travel by minivan to the private pier in Phang Nga, then continue by speed catamaran.
• Several snorkeling stops: The route includes Island 5, Bangu Island, Ko Pa Yu, West of Eden, and areas near Island 7.
• Thai buffet on Ko Miang: Lunch comes with fresh fruit and time for swimming, snorkeling, or a walk across the island.
• Sailing Rock viewpoint: The final island visit includes beach time and a climb to the landmark viewpoint on Ko Similan.
• Extra national park fee: The listed price is $124.11 per person, but you must also pay 400 THB per adult or 200 THB per child.

What the $124.11 price really buys you

At $124.11 per person, this is not a cheap beach outing. It is a full-day package that covers hotel transfers from Phuket, the road trip to Thap Lamu, round-trip speed catamaran transport, snorkeling gear, a Thai meal, fresh fruit, an English-speaking guide, and full travel accident insurance.

That bundle has real value. Booking transport separately would make this day harder to arrange, especially since the Similan Islands are far from Phuket and the boat leaves from Thap Lamu in Phang Nga. You also avoid renting masks, snorkels, fins, and life jackets on your own.

Remember the national park charge. Adults pay 400 THB and children aged 4 to 11 pay 200 THB. That extra amount means the final cost is higher than the headline price, but lunch, transfers, and equipment soften the blow.

I would choose this trip if I wanted one organized day in the Similans and did not want to manage several separate bookings. I would skip it if I preferred a slow beach day with long periods in one place.

The early road to Thap Lamu

The day starts around 6:00 a.m. with hotel pickup from Phuket. A minivan collects you from areas across the island, and the stated tour duration includes both pickup and drop-off time.

That detail matters. The advertised 11 to 12 hours is not 11 to 12 hours on the islands. You first spend about an hour on the road, then check in at the private Seastar pier at Thap Lamu. After the sea portion, you repeat the transfer back to Phuket.

At the pier, you collect snorkeling equipment and get hot drinks and a bakery item. This is a useful start because the morning begins early, and you may not have much time for breakfast before pickup.

The road transfer is the least exciting part of the day. One practical advantage is that it is included, so you do not need to find your own way to Phang Nga. The downside is that the outing can feel long before you even reach the water.

Speed catamaran across the Andaman Sea

From Thap Lamu, the speed catamaran takes about 45 minutes to reach the Similan Islands. The boat makes the trip faster than a slower standard vessel, but you should still expect motion, spray, and a busy group setting.

The maximum group size is 70 people. That is a sizeable group, especially when several boats arrive at the same snorkeling area. The guide helps coordinate the route, equipment, and stops, but this is not a private sailing trip.

Bring a towel, swimsuit, sunglasses, sunscreen, hat, camera, and passport or identification. Secure loose items before the boat moves. Sunscreen is especially important because much of the day takes place on open water or exposed beaches.

The tour includes life jackets, and you can use them while snorkeling if you are not a confident swimmer. The activity is not recommended for people who are pregnant or who have high blood pressure, heart disease, or bone diseases.

Island 5 starts the snorkeling

The first water stop is near Island 5, where you can look for colorful fish and coral formations. This is a good introduction to the underwater side of the Similans because it gets you into the water early rather than saving all the snorkeling for the afternoon.

I would treat this as a chance to test your mask and fins, not as the only major snorkeling session. With the number of stops planned, the schedule keeps moving. You may get good views of fish and reef structure, but you should not expect unlimited time in the water.

Conditions can change with weather and sea movement. The trip requires good weather, and the operator may cancel for safety if conditions are poor. That policy is sensible for a boat day, but it means your date is not guaranteed.

Ko Miang brings lunch and breathing room

Ko Miang gives the schedule its longest island stop, at about two hours. You can walk across the island, swim, snorkel, and eat a Thai buffet with a scenic view.

This is one of the more useful stops because it breaks up the repeated pattern of boarding, snorkeling, and reboarding. A meal on land gives you a chance to dry off and settle down before the next water stop.

The buffet includes Thai food and fresh fruit. The information provided does not specify individual dishes, so I would expect a mixed Thai meal rather than plan around a particular menu.

Two hours sounds generous, but it can pass quickly once you account for eating, changing, walking, and finding a good place to sit. If you want to swim, do that before you get too comfortable at lunch.

Bangu Island and the later water stops

Bangu Island, also called Koh 9, is scheduled for about an hour of snorkeling and swimming. It is one of the places where the Similan scenery and underwater setting come together, with rock formations around the water and the chance to see reef fish.

After Bangu, the boat continues to Ko Pa Yu, also called Ko Jed, for another snorkeling and swimming stop. Later, the route includes West of Eden for about 30 minutes, followed by another 30-minute snorkeling stop near Island 7.

This is the part of the trip that can feel rushed. The itinerary includes many water stops, but each short session requires time to gather the group, enter the water, snorkel, and return to the boat. You get variety, but not much stillness.

I would rather have one or two longer snorkeling periods than several brief ones. That said, the variety is useful if you are unsure which area you will like best. You get several chances to find clear water, interesting rock shapes, or fish activity.

Ko Similan and the famous Sailing Rock

The route eventually reaches Ko Similan, often identified as Island 8. This is the main scenic stop, with up to two hours for swimming, snorkeling, and relaxing on the beach.

The beach is the place to slow down. After the road transfer and several water entries, you may appreciate simply sitting on the sand and looking back toward the sea. If you still have energy, this is also the setting for the Sailing Rock viewpoint.

The rock, known locally as Ao Kuerk Bucht or Sailing Rock, is the landmark associated with Similan Island. The climb to the viewpoint takes about 30 minutes. You can look over the island and water from above, then return for more beach time.

Wear secure footwear if you plan to climb. The provided information does not describe the path in detail, so I would not treat the viewpoint as a casual stroll for everyone. You can skip the climb and use the time for swimming or resting.

This final stop is a major reason to choose the tour. You are not limited to snorkeling from a boat. You also get the classic Similan view that makes the islands recognizable in photographs.

Snorkeling quality and the coral question

The Similans remain beautiful, but you should set realistic expectations about the reef. Some coral around the islands is damaged or dying, so the underwater scenery may be uneven from one stop to the next.

You can still see fish, coral, and rock formations, but this is not a promise of perfect reef health. Water clarity, weather, crowding, and the condition of each site will affect what you see.

If sea turtles are important to you, ask the guide early in the day which stops offer the best chance. The tour description says you might see turtles and even wild dolphins, but neither sighting is guaranteed. I would enjoy those as lucky extras, not as the main reason to book.

The practical trick is to stay alert when the guide explains each location. A short question about turtles or the best snorkeling section may help you use your limited water time well.

How crowded and rushed will it feel?

The group can include up to 70 people. That number affects almost everything: boarding, collecting equipment, entering the water, finding space on the beach, and returning to the boat on time.

The speed catamaran helps cover distance, but it does not remove the limits of a group schedule. You cannot decide to stay another 20 minutes at a favorite snorkeling site. The guide needs to move everyone through the route.

I would describe the pace as active rather than restful. You visit many places, but you also spend time moving between them. If you want a quiet day with long swims, the schedule may frustrate you.

If your priority is seeing the greatest range of Similan highlights in one day, the busy plan works better. You get Island 5, Ko Miang, Bangu, Ko Pa Yu, Island 7, Ko Similan, and Sailing Rock in one organized outing.

When to choose this over Phi Phi or James Bond Island

The Similans should come early in your Phuket plans if you want them to make the biggest impression. One useful piece of advice is to schedule this outing before Phi Phi and James Bond Island, not after several other boat days.

The reason is simple. The Similans are a long, full day with an early pickup, repeated water stops, and a long return. After several similar excursions, the format can feel repetitive, even though the islands themselves are striking.

The scenery here is also different from Phuket’s more familiar day-trip routes. You get a national park setting, multiple snorkeling areas, island beaches, and the Sailing Rock viewpoint rather than a single famous bay.

I would choose this tour for a first visit to the Similans when convenience matters. I would look for a smaller or slower option if your main goal is peaceful snorkeling and personal attention.

Who should book this day trip?

This outing suits you if you:

• Want hotel pickup rather than arranging your own trip to Thap Lamu
• Enjoy swimming, snorkeling, and several short stops
• Like having lunch, equipment, and transfers handled in one booking
• Can manage an early start and a full 11 to 12-hour day
• Want to see Sailing Rock as well as the underwater sites
• Are comfortable in a group of up to 70 people

It is less suitable if you dislike boat motion, need a relaxed pace, or want long stretches of quiet beach time. It is also not recommended for pregnant people or people with high blood pressure, heart disease, or bone diseases.

Children aged 4 to 11 qualify for the child ticket. The information does not provide a lower age recommendation beyond that, so check the booking details carefully if you are bringing a younger child.

Booking, cancellation, and practical details

Confirmation is provided when you book. The operator asks for passport details after booking so the national park entry ticket can be purchased in advance. Keep your identification available and make sure the name details are correct.

Free cancellation is available up to 24 hours before the start time. Changes or cancellations inside that 24-hour window are not accepted for a refund.

The trip depends on good weather and a minimum number of participants. If poor weather or low enrollment causes cancellation, you are offered another date, an alternative activity, or a full refund.

The meeting point is the Seastar private pier at Thap Lamu, although hotel pickup from Phuket is included. The activity ends back at the pier before the return transfer to your hotel.

Should you book the Similan Islands speed catamaran tour?

I would book it if you want a well-organized first look at the Similans and value included transport, lunch, gear, and several different stops. The beaches, rock formations, Thai buffet, and Sailing Rock viewpoint give you more than a simple snorkeling trip.

I would not book it expecting a quiet marine outing or perfect coral. The long transfer, large group, short snorkeling sessions, and busy schedule are genuine tradeoffs. Put this near the start of your Phuket island-hopping plans, ask about the best turtle sightings, and accept that the day is about variety rather than lingering in one place.
