We were whisked away to paradise!
Excellent tour! Great value for the price. The crew was very friendly (even sometimes too many jokes!) but they took very well care of our family, We loved the snorkeling at Koh Yao Yai, the food was excellent. The cruise itself was so relaxing taking the best sites and we loved this as its less tourists here as well so we felt very special. I Asia Thailand picked us on time to our hotel but we came back a bit late as there was a bit of traffic jam. I would recommend this tour very much.
Response from the operator: Hello escapechristine, We are so happy you were whisked away to paradise! We do appreciate your comments and thank you so much for booking with I Asia Thailand. Regards, Nick

4 Islands by Speedboat - Koh Yao and the three Khai Islands: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Phuket.
How much does 4 Islands by Speedboat - Koh Yao and the three Khai Islands cost?
+
Prices start at ฿2,200 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Phuket usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does 4 Islands by Speedboat - Koh Yao and the three Khai Islands take?
+
Plan for about 9.5 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Phuket is not rushed.
Is 4 Islands by Speedboat - Koh Yao and the three Khai Islands worth it?
+
It holds an Outty Ranking of 43 out of 100, which we label "Worth a Look". That score blends traveler sentiment (5/5 across 1 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Phuket, and how flexible the cancellation terms are.
Can I cancel or reschedule 4 Islands by Speedboat - Koh Yao and the three Khai Islands?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is 4 Islands by Speedboat - Koh Yao and the three Khai Islands suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 9.5-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book 4 Islands by Speedboat - Koh Yao and the three Khai Islands?
+
Around 0 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Phuket can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Phuket and add a light layer if any part of the 9.5-hour experience runs outdoors or after sunset.
Where does 4 Islands by Speedboat - Koh Yao and the three Khai Islands start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Phuket within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Phuket?
+
On Outty we rank every Phuket experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Southern Flavors Phuket Food Tour with 15+ Tastings, James Bond Island by Big Boat w/ Sea Cave Canoeing and Lunch, Phuket Thai Cooking Class with Market Tour Option. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Phuket?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Phuket?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
What is included in 4 Islands by Speedboat - Koh Yao and the three Khai Islands?
