REVIEW · THAILAND
SIMILAN ISLAND BY SPEED BOAT FROM PHUKET
The main draw here is the Similan Islands, a chain of white-sand beaches, granite boulders, and clear turquoise water. You get several chances to swim and snorkel, plus time on Koh Miang and Koh Similan rather than simply viewing the islands from the boat.
I like the early hotel pickup because it gives you a full day on the water, and I like that the price includes the national park fee, lunch, equipment, drinks, and round-trip transport. The main concern is the long speedboat day and changing coral conditions. One recent verified booking reported that the coral reef looked dead, so you should book for the beaches and scenery as well as for snorkeling.
Key points to know before booking

- Expect a very early start: Pickup from Phuket hotels runs between 5:30 and 6:45 AM.
- Three main snorkeling areas: You visit Islands 5 and 6, Christmas Point or Namchai Bay near Island 9, and the waters around Island 8.
- Koh Miang provides a proper land break: You get lunch, beach time, and a chance to relax at Princess Bay.
- Sail Rock is the big photo stop: You can swim, take pictures, and climb to the viewpoint on Koh Similan.
- The $131 price covers the useful extras: Transport, lunch, drinks, snorkeling gear, life jacket, towel, insurance, guide, and park fee are included.
- Sea conditions matter: The speedboat ride can be tiring, and the underwater scene may not match the best promotional photographs.
Why the Similan Islands make a strong day trip

The Similan Islands appeal because they offer more than one kind of beach day. You have pale sand, large granite rock formations, green island views, open sea, and several scheduled water stops. That variety helps justify the long ride from Phuket.
The tour is also arranged around the islands that are most useful for a first visit. Islands 5 and 6 are used for the opening snorkeling stop. Koh Miang, also called Island 4, gives you a proper lunch break. Island 9 provides another snorkeling area, and Island 8 brings the famous Sail Rock viewpoint.
That mix matters. A trip built around one snorkeling stop can feel disappointing if the water is cloudy or the coral is in poor condition. Here, you at least have beaches, viewpoints, swimming, and photographs to fill out the day.
Still, this is not a quiet island escape. It is an organized day trip with an early pickup, a fast boat, fixed departure times, and several activities packed into one schedule. I would choose it for scenery and variety, not for a slow, private beach day.

The 5:30 AM start from Phuket

Hotel pickup begins between 5:30 and 6:45 AM, depending on your location in Phuket. The transfer is by van and takes about an hour and a half, so the first part of the morning is mainly transport.
That early start is necessary because the islands are a long way from Phuket by road and boat. It also gives you a better chance to enjoy the islands before the day feels too crowded or rushed. Bring a hat, beachwear, personal medication, and a copy of your passport or identity card.
At the check-in point, you collect snorkeling equipment and can have hot drinks and bakery items. This is a useful touch because you may leave your hotel before breakfast. Tea and coffee are included, along with drinking water and soft drinks.
You should think carefully about the return timing if you are flying. The trip is not recommended if you have a domestic flight before 10:00 PM on the same day. That leaves a wide buffer, but the schedule still involves a long return by boat and van.
Speedboat travel to the islands

The boat leaves at about 9:00 AM. Speedboats save time compared with a slower vessel, which is important when your day includes several islands. The tradeoff is comfort. You should expect wind, spray, engine noise, and movement on the water.
A life jacket and accident insurance are included. The crew also provides a beach towel, which saves space in your luggage. Alcohol is not included, and there is no reason to plan on buying it as part of the day.
The boat ride is part of the experience, but it is also where the physical demands begin. If you are prone to motion sickness, personal medication is especially worth packing. The stated restrictions also exclude pregnant women, people with heart problems, babies under one year, and people over 70. The information also says the trip is not recommended for people over 80, so older participants should read those limits carefully.
Islands 5 and 6: your first snorkeling stop

The first island stop comes at about 10:50 AM near Islands 5 and 6. This is your introduction to the underwater side of the park, with time to see fish and coral before heading to a beach.
The schedule calls this a chance to appreciate the variety of fish and colorful coral. That description is appealing, but you should keep your expectations measured. Coral health can vary by location and season, and one recent verified booking reported that the coral looked dead. That does not prove the same conditions will affect every departure, but it is an important warning for anyone booking mainly for underwater scenery.
I would treat this stop as one part of the day rather than its sole purpose. If the water is clear and the reef is in good shape, it may be the strongest snorkeling moment. If not, you still have Koh Miang, Sail Rock, and the beaches ahead.
The tour provides snorkeling equipment and life jackets, so you do not need to bring your own gear. You may still prefer your own mask if fit and comfort matter to you.

Koh Miang and Princess Bay
At about 11:40 AM, the boat heads to Island 4, known as Koh Miang. The schedule gives you a break at Princess Bay, followed by lunch at noon.
Koh Miang is valuable because it changes the rhythm of the day. After the boat ride and first swim, you can get back on solid ground, dry off, eat, and take photographs. The island has the soft white sand and turquoise water that define the Similan image, while the surrounding granite formations give the scenery more character than a standard flat beach.
Lunch is included, but the information does not specify the exact menu. You should think of it as a convenient included meal rather than a reason to choose the trip. Drinking water, soft drinks, tea, and coffee are also provided.
The one-and-a-half-hour stop gives you enough time for a meal and some sightseeing, but not an unstructured afternoon on the beach. Keep an eye on the departure time. With a boat-based tour, the group cannot wait indefinitely for someone who wanders too far along the shore.
Island 9, Christmas Point, and Namchai Bay
After lunch, the boat leaves Koh Miang at about 1:00 PM and heads to Island 9, also called Koh Ba Ngu. The planned snorkeling area is Christmas Point or Namchai Bay.
This stop is described as a highlight because of coral reefs and colorful fish. It gives you another chance to see underwater life after the first snorkeling stop, and it may offer different conditions depending on visibility and the exact bay used that day.
The schedule calls for roughly an hour and fifteen minutes before the next island visit. That time includes the boat approach and snorkeling, so you should not expect unlimited time in the water. Still, the repeated stops are useful. You get more than one opportunity for clear water, and you can compare the different areas instead of relying on one brief swim.
Again, the reef condition is the key unknown. The promotional description is optimistic, but the recent report of dead coral makes this a trip where scenery should matter as much as fish and reefs. You may find the water attractive even if the coral is underwhelming, but you should not book on the assumption that every reef will look untouched.
Sail Rock on Island 8
At about 2:15 PM, the tour reaches Island 8, Koh Similan, for the landmark known as Sail Rock. This is the most flexible stop on the schedule. You can relax, swim, take photographs, or climb to the viewpoint above the rock.
Sail Rock gives the day its strongest land-based sight. The granite formation rises above the beach and provides a clear reason to bring a camera, even if snorkeling conditions have been disappointing. From the viewpoint, you can look over the white beach and bright water, with the rock formations helping explain why the Similan Islands are so widely photographed.
The visit lasts about two hours in the broader itinerary description, although the detailed schedule places departure at 3:30 PM. That should provide a reasonable amount of time for swimming, pictures, and the climb. Wear secure footwear if you plan to use the viewpoint, and keep your belongings simple because you will be moving between beach, water, and boat.
This is also your last major island stop, so make it count. If you prefer land to snorkeling, Sail Rock and the beach at Koh Similan may be the part you enjoy most.
The return to Phuket and what is included

The boat leaves the Similan Islands at about 3:30 PM and reaches Tub-lamu Pier around 4:50 PM. At the pier, the return welcome includes drinks, snacks, papaya, fried chicken, and ice cream before the van ride back to Phuket.
That food stop is a thoughtful end to a long day. You may be tired and hungry by then, and having something available before the road transfer is more useful than another formal sightseeing stop.
The advertised duration is eight hours, but the full hotel-to-hotel day can feel longer because pickup starts before 6:00 AM and the return includes both pier and van transfers. Check the exact starting time for your hotel when booking. The tour includes lobby pickup in the Phuket area, but the supplied information does not list individual hotel surcharges or a precise drop-off time.
At $131 per person, the value is fairly strong if you need transport from Phuket and do not own snorkeling gear. You are paying for the boat, van, guide, park admission, lunch, drinks, insurance, towel, and equipment in one package. The price is less attractive if your priority is private service, a slower pace, or guaranteed coral quality.
Who will enjoy this trip most
I would recommend this excursion to you if you want to see the Similan Islands in one day without arranging separate transport, boat tickets, park fees, food, and equipment. It suits active visitors who are comfortable with an early morning, a fast boat, swimming, and a structured timetable.
It is also a good match if you want variety. You can snorkel, eat on Koh Miang, swim, photograph Sail Rock, and see several beaches and rock formations. You are not limited to one beach or one water stop.
I would be more cautious if you have mobility, heart, or pregnancy concerns, or if you dislike boat movement. The tour specifically excludes several groups, including pregnant women, people with heart problems, babies under one year, and people over 70. The published information also mentions people over 80, so age restrictions should be taken seriously.
The experience may also disappoint you if your only goal is perfect coral. Conditions can change, and the report of dead coral is a clear reason to keep expectations realistic. The beaches and rock scenery offer a useful second reason to go.
Practical booking advice for this Similan day
You can cancel up to 24 hours in advance for a full refund, and the reserve-now, pay-later option keeps your plans flexible. If you need to change the travel date after 5:00 PM, the stated charge is 1,000 Baht per person.
Illness or injury can avoid that charge when supported by a medical certificate. An accident can also qualify when supported by a police report, but if you are traveling with another person, the exemption applies only to the person named in the document. The other person can still face the 1,000 Baht fee.
Bring biodegradable insect repellent, a hat, beachwear, and medication. A passport or identity card copy is accepted according to the tour information. Alcohol and souvenirs are not included, so budget separately if you want either.
Should you book this Similan Islands speedboat tour?
Book it if you want an efficient first look at the Similan Islands and value an all-in-one package. The combination of Koh Miang, multiple snorkeling areas, lunch, Sail Rock, park fees, and hotel transport gives you plenty to do for the price.
Skip it if you need a calm, private day or if damaged coral would ruin the experience for you. The strongest reason to go is the full mix of beaches, granite formations, swimming, viewpoints, and snorkeling, not a guarantee of perfect reefs. If that balance suits you, this is a practical way to reach one of Thailand’s most scenic island groups from Phuket.
