Great Tour & Atmosphere — Plankton Not Guaranteed
We really enjoyed this tour overall — the atmosphere was great, the team was friendly, and we appreciated that no one rushed us. The stops were long enough to swim, relax, and truly enjoy the beautiful islands. It felt like a well-organized and pleasant experience from start to finish. The only downside for us was the bioluminescent plankton part. We booked the tour specifically because we really wanted to see the glowing plankton — but unfortunately, we didn’t see any that night. We understand this is a natural phenomenon and not the operator’s fault, but it’s good for future travelers to know that the plankton isn’t guaranteed. If you choose this tour mainly for that experience, just keep in mind that you may not get what you’re paying for. Apart from that, everything was lovely and we had a great time!
Response from the operator: Thank you for sharing your experience. We’re delighted to hear that you enjoyed the tour and had such a positive time overall. We appreciate your note about the bioluminescent plankton it’s a natural phenomenon and not guaranteed, so your feedback is very helpful for future travelers. We’re glad the rest of your experience was lovely and hope to welcome you on another adventure soon. Best Regards, Tawan Oh-Hoo Team

Definitely worth doing
We had such an incredible time on the Krabi 7 Island Sunset Tour! The staff really made the trip extra special – they were so helpful with taking photos and knew all the best spots for those perfect shots. Their advice on snorkelling was spot on too, which made it easy to enjoy the underwater world. Each island stop gave us just the right amount of time to explore if you don’t mind shorter visits, and the sunset was absolutely beautiful to watch from the boat. The real highlight, though, was the bioluminescent plankton – such a magical experience and unlike anything we’d seen before. All in all, a well-organised, friendly, and memorable tour that I’d definitely recommend!
Response from the operator: Thank you for your wonderful review. We're so happy to hear you had an incredible time on the Krabi 7 Island Sunset Tour. We appreciate your kind words and high recommendation, and we hope to welcome you again for another unforgettable adventure. Best regards, Tawan Oh-Hoo Team

A fantastic 7 island trip
An absolutely fabulous all day tour guided by our amazing tour guide Palm. She was so informative and gave us great information all day long. We were really looked after. The different islands are spectacular and breathtaking. We had several stops and time was set aside to snorkel. The food was delicious. Palm our tour guide was exceptional. I would highly recommend this tour. You’ll love it.
Response from the operator: Thank you for your wonderful feedback. We’re absolutely delighted to hear that you had such a fabulous day overall. Your recommendation truly means a lot to us, and we hope to welcome you back again for another unforgettable experience. Best regards, Tawan Oh-Hoo Team

Why this scores 71
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Krabi 7 Islands Snorkeling & Plankton Night by Big Longtail Boat: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Krabi.
How much does Krabi 7 Islands Snorkeling & Plankton Night by Big Longtail Boat cost?
+
Prices start at $45 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 7 Islands Snorkeling & Plankton Night by Big Longtail Boat take?
+
Plan for about 7 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 7 Islands Snorkeling & Plankton Night by Big Longtail Boat worth it?
+
It holds an Outty Ranking of 71 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.2/5 across 166 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Krabi, and how flexible the cancellation terms are.
Can I cancel or reschedule Krabi 7 Islands Snorkeling & Plankton Night by Big Longtail Boat?
+
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 7 Islands Snorkeling & Plankton Night by Big Longtail Boat suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 7-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Krabi 7 Islands Snorkeling & Plankton Night by Big Longtail Boat?
+
Around 58 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 7-hour experience runs outdoors or after sunset.
Where does Krabi 7 Islands Snorkeling & Plankton Night by Big Longtail Boat 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.
