No more unique than the other boat trips

Always fun to sail on these beautiful waters and look for islands. There are 7 islands ‘announced’ in this tour, and yes...all in all you see 7 (even a lot more:) Unfortunately, only 2 places are really stopped and anchored. The ‘snorkeling’ happens in a place that is certainly not one of the most beautiful in Thailand; murky water (immense boat traffic), almost colorless coral and yes... still some fish. After an improvised buffet you watch the sunset with hundreds of others with which you must of course be 'lucky'. When you return to dusk, you will stop at a place where you can go for 5 minutes in the water to see some glowing ‘bubbles’ underwater if you flap your hands... it is certainly not an experience you will talk about for weeks to come:) All in all nice afternoon, but little different from the many other boat trips in Krabi. Mass is checkout is definitely applicable here!

Round day

It's been a really cool experience. The very attentive guide even showed us fish when we were snorkeling. Dinner was fine.

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!

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!
