UNSAFE DONT GO
Imagine being in the darkest place in the ocean with a bunch of people who don’t speak any English they don’t have lifejackets available for you. They don’t have snorkel equipment ready for you and there’s boat smashing into each other in the dark. You can’t tell if you’re supposed to get in the water or if you’re supposed to put on a lifejacket, nobody helps you. It was probably the most unsafe thing I’ve ever done. I’m surprised. Even had any idea who was in what boat and who was going where I wouldn’t be surprised if we lost a few people at sea while we right there I would never ever recommend doing this to her ever we literally hate this place. UNSAFE

Only 10 min exploring allowed of bioluminescent are.
Disappointed in tour. Only had 10 minutes at bioluminescent snorkeling. The description of your makes it sound like you get a good amount of time.
Response from the operator: Thank you for your honest feedback. We’re truly sorry to hear that you felt disappointed with the limited time for the bioluminescent snorkeling. We understand how this highlight can be something guests really look forward to, and we regret that it did not meet your expectations. The duration can sometimes be affected by sea conditions, safety considerations, or timing constraints, but we appreciate that this should be communicated clearly. We will review how the experience is described to ensure it sets the right expectations. Thank you for sharing your experience, your feedback helps us improve. We would welcome the opportunity to provide you with a much better overall experience in the future. Best Regards, Oh-Hoo Team

Just an okay time
Ok trip. The guide was fantastic snd tried really hard. Older boat, water soaked many of us. Not great snorkel gear bad water. Trashy beach with garbage and debris all over. They did have a storm so a little grace but overall just an okay experience compared to the many others we had.

This was run by Mariam tours and is actually the “7 islands sunset tour”
Don’t be fooled, this is the same crappy 7 islands sunset tour run by Mariam Tours and marketed under all kinds of different names. I was ill afterwards and threw up for several hours that night from the food. We only swam with the plankton for 5 mins and the rest of the 10+ hours was spent mostly waiting around. If you are mainly interested in seeing plankton I don’t recommend this tour.
Response from the operator: Thank you for your review of our Bio Luminescent Swimming From Krabi. We are truly sorry that your experience did not meet expectations and that you felt unwell afterwards. Please be assured that the meals provided on our tours are freshly prepared daily with care for quality and hygiene. Nevertheless, we take your feedback seriously and will communicate with our partner to further review and improve both the program and overall service. We greatly appreciate your input as it helps us enhance customer satisfaction. Best regards, Oh-Hoo Team

The island tour was nice...
The island tour was nice and well organised but please don’t book this trip as we did purely for the bioluminescent part. It was literally a bucket of water in the boat not the beach setting as the photo would suggest

Why this scores 55
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Bio Luminescent Swimming From Krabi: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Krabi.
How much does Bio Luminescent Swimming From Krabi cost?
+
Prices start at $42 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 Bio Luminescent Swimming From Krabi 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 Bio Luminescent Swimming From Krabi worth it?
+
It holds an Outty Ranking of 55 out of 100, which we label "Worth a Look". That score blends traveler sentiment (3.6/5 across 88 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 Bio Luminescent Swimming From Krabi?
+
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 Bio Luminescent Swimming From Krabi 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 Bio Luminescent Swimming From Krabi?
+
Around 31 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 Bio Luminescent Swimming From Krabi 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.
