🧡We had an amazing time on the Railay + Plankton tour with Barracudas. Everything was well organized, and the team was friendly and professional. Railay Beach was beautiful and relaxing, and the highlight was definitely swimming with the glowing plankton at night🌌such a special experience. If you’re looking for an afternoon trip with sunset🌤️, we highly recommend the Barracudas tour. It’s a great option to enjoy stunning sunset views and end the trip with plankton swimming.🏊

Apparently snack box was late therefore we had less time in our first stop and was extremelly rushed, the rest went ok. Small sample of plankton, not the one you see in the videos online. Not too bad overall

Beautiful places to see. Unfortunately it was very cloudy so no sunset visible. Swimming with the plankton was cool.

The guide was accomodative. He changed the programme as it was just 4 of us. We skipped the 1.5km walk. The planktons are visible. However, we didnt see anyone even from the other boats diving into the water in the dark. Alex our guide was smoking and it was not a cigarette. Ditto for our boat driver. Alex is a good guide but he should quit smoking whatever it is he smokes. His fingers had a tremor.

Railey beach was great, the plankton was non-existing. The picture you see in the activity is not taken in Krabi!!!!! So don’t expect to see any plankton or swim with plankton.

The trip felt very unorganised and a bit chaotic. We had to wait around at the dock for about 30 minutes with no one explaining why but it turned out we were waiting for another guide (even though there was already one and two trainees). The boat was still wet and sandy from what seemed like an earlier trip. When we got to the island it felt very rushed and we weren’t given much info, due to the delay in waiting for the guide we only had about 30 ish minutes on the beach for the sunset. Then on our way back we had to tow another boat from the same company back to the dock which was very chaoti

Went on the Railay Sunset Trip with Barracudas Tour and honestly had the best time. The staff were so friendly, the boat was comfy, and the views were unreal. Sunset at Railay is something you have to see!

The one trip incorporated a boat trip as well as several “hotspots” which we enjoyed. Harry, the guide, was really friendly and helpful. We were also provided with blankets and some snacks for the beach sunset. Overall I think the trip was great value for money. Quite a bit of walking involved which some may not be able to keep up with.

we had two guides one called Alex who was the main guide and seemed to be in a rush the whole time and the trainee called Freshy he was really sweet and very helpful. sailing on the longboats was lovely as well as swimming with the Plankton although we were advised not to do this strangely enough as it was one of the highlights of the tour and there wasn't much Plankton to be honest with you. we were disappointed in the way we were rushed through the various pathways on the beach and weren't given any explanation at all about the rock formations or the nature surrounding us.
