Fantastic experience
My partner and I were on a Contiki tour which went on this 4 island sunset cruise, it was amazing, great reefs & islands, saw plenty of interesting wildlife, the guides had go-pros during snorkelling & sent us the videos later. We were even able to chill on the roof with comfortable laying mats, cocktails and music. All around great day trip & the cruise guides were great. Great for groups or couples.

An absolute must-do in Krabi!
This was hands down one of the BEST experiences of our entire trip to Thailand! Everything about this cruise was absolutely perfect, from the delicious food and incredible atmosphere to the breathtaking beaches and unforgettable snorkeling experiences. Michael was so warm, attentive, and genuinely made sure everyone was having the best possible time. You could really feel how much passion he puts into creating such a special and unforgettable experience. The snorkeling was absolutely amazing 🐠🤿, and the beaches were breathtaking. But the night snorkeling with the glowing bioluminescent plankton under the stars was truly magical! Swimming in the dark and watching the water light up around us with every movement felt like something straight out of a fairytale. This alone was worth the entire experience! And the photos they took for us were such a wonderful bonus, we now have beautiful memories to look back on forever! If you’re visiting Krabi, DO NOT miss this cruise! It was so much more than just a boat trip, it was a truly unforgettable experience. We will absolutely be back and will recommend this experience to everyone! ❤️

Best experience ever
This honestly was a perfect experience for my husband and I , he didn’t know how to swim so we had to a few experiences like this where he could not participate, unfortunately lol , it this time … he absolutely could be involved and he absolutely had one of the best experiences of his life !!! He felt safe even while he was drinking whiskey and enjoying himself , they took care of him and when he decided to be brave when he shouldn’t have… the way they all rushed over to him to save him really made me proud and excited to be there , they all truly cared and made the experience for us both absolutely amazing !!!

Why this scores 96
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Krabi.
How much does Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim cost?
+
Prices start at $139 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Krabi usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim take?
+
Plan for about 6 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 Krabi is not rushed.
Is Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim worth it?
+
It holds an Outty Ranking of 96 out of 100, which we label "Peak Performance". That score blends traveler sentiment (4.9/5 across 1,996 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable most popular in Krabi, and how flexible the cancellation terms are. Scoring 90 or above puts it in the Outty 90+ Club, the top tier of everything we rank.
Can I cancel or reschedule Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim?
+
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 Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 6-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim?
+
Around 699 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 Krabi 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 Krabi and add a light layer if any part of the 6-hour experience runs outdoors or after sunset.
Where does Krabi 4 Island Sunset Snorkeling Cruise + Bioluminescent Swim 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 Krabi 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 Krabi?
+
On Outty we rank every Krabi experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Full-Day Phi Phi Islands Tour with Lunch from Krabi, Phi Phi Early Bird & 4 Islands - Day Tour by Speedboat From Krabi, Railay and 4-Island Sunset Speedboat Cruise with Night Snorkel. 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 Krabi?
+
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 Krabi?
+
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.
