We’ve tried both... - We’ve tried both speedboat and long tail boat, but we preferred the long tail boat more. It brought us closer to nature, and it was airy. We were lucky with the weather and got to snorkel for over 2.5 hours. Towards the end of the trip, we had a short round of evening snorkeling and got to see some bioluminescent plankton. The guide was clear, spoke good English, and kept to the schedule. I would definitely do it again.

This tour was the highlight of trip!! - This tour was the highlight of my trip!! The operators of this tour at Miriam were awesome!! The snorkeling spots they took me to were the best. Tons of fish and beautiful coral. But the highlight was the bio luminescent swimming!! So glad I took this tour, I loved it!!!

My favorite experience in Thailand! - This tour was the highlight experience of my 2 weeks in Thailand! My flight arrived late at the airport, I immediately grabbed a taxi and headed to my hotel. The tour had already come to pick me up and I had missed them. The front desk called and woman on the phone ( who was the only person on my entire trip that I did not find warm and fuzzy) informed me that the boat was leaving in 10 minutes, my hotel was 25 minutes away and they would not wait for me so don't come. She did not realize who she was talking to, I am a die hard and do not give up that easily. Realizing that many tours get started late I had my taxi driver proceed to the pier. Unfortunately, the boat had in fact already left. The workers at Miriam Tours were so caring and concerned. They were trying to figure out what they could do. They put me back on the phone with the woman from before who scolded me saying " I told you not to come". After hanging up with her, I asked the woman on site, was they anything I could do. Could I get a boat to take me out to meet them? She said she could book me a private boat to do my own tour that would be identical and I felt the rate was very reasonable considering the circumstances. From that moment forward I was treated like a queen. The young man transported me to the pier and I immediately boarded my own private long boat with a skipper named BeBe. He took such amazing care of me and was incredibly kind. We toured past a few islands and then met up where the other boat was. He suited me up with a life preserver and in I went snorkeling. So many fish, so many beautiful kinds of fish! It was amazing!!! Then off to another island for exploring and another island for more snorkeling, then to Railay beach to meet with the others for a delicious dinner. The best part was the night snorkeling after dinner. The Bio Luminescent swimming was outstanding!!! Thank you Miriam tours and thank you BeBe for such amazing experience that I could have missed.

Good day trip out - This is definitely an activity to do if it’s your first time in Thailand. Apart from the pick up being late everything else was spot on. As it is the off season the beaches weren’t crowded and it was a good experience.

Otherwordly magic - We were a little hesitant based on some of the reviews saying they were disappointed, but we loved it. The boats were a little crowded and the pickup was a little disorganized but not too bad. The swimming spots were great, and we enjoyed the viewpoint non-swimming areas as well. The food was good and had good vegan options too. Now to the point of booking the bioluminescent tour: most of the snorkeling was done before dark,but after we ate, they took us one last time out to snorkel after dark and explained that you will see the bioluminescent plankton light up when there's movement. So the pictures where the water is all illuminated is much exaggerated but when you get in the water and move your hands to swim or just move them in front of you, the plankton light up like magic. We only had ten to fifteen minutes in the water there, I think safety reasons for all the boats in the dark, but it was worth it. It was a once in a lifetime experience and I don't regret booking this one on top of another island hopping snorkeling tour the next day, plus the islands were different.

A Great Afternoon - Very well organized trip starting from pick up to drop off. However, the plankton stop was brief as it was too dark to enter the water. The guide did not recommend us to snorkel as well but i believe there are few of us who wished to try.

Meh. - This tour was a little disappointing. The island hopping was nice but it had rained that morning so the waves were choppy. This activity had advertised a beach bbq but it ended up being a catered dinner at a resort. Food had bbq flavor but we didnt bbq on the beach. However, there was plenty of vegan and vegetarian food to accomodate our diets. It poured a crazy storm after dinner. We thought we would be swimming with the bioluminescent plankton on the beach but instead we only got to see it when it was dumped from a bucket into out boat, nothing like the photo. we understand that weather prob played a part in our experience but we do feel like maybe the description should be updated so our expectatiobs werent so high.

Underwhelming last minute trip - Last minute trip turned out to be rather disappointing. Snorkelling wasn't great and even though the boat stopped at a few different sites it was all very much the same. Coral was dead and only an abundance of tiger fish seemed to be in the area. The snorkels provided were also poor quality. The one I had leaked badly which made snorkelling almost impossible. Would recommend you take your own. Plankton was also nothing like the pictures in the advertisement, which was a let down and appears to be false advertising. Instead it was just really small flickers of light when you waved your hands around in the water. This was for only 10 minutes at the end of the trip BBQ was extremely poor quality and not very nice at all Also the longboat we were onboard broke down a total of 4 (steering shaft kept popping out). Seemed a long standing issue as the crew knew how to fix the problem almost straight away

Don't go for the plankton you'll be disappointed - The trips to the islands were great! Some interesting features. Tea was a good buffet at a nice restaurant. Please make sure you wear water shoes and swimwear because whether you want to swim or not, you'll get wet getting in and out of the boat! We took a 3 hour car drive to do this trip for the photo luminescent plankton, though and honestly, it was underwhelming. Firstly, no way was I getting into the water in the pitch black in a relatively open sea and secondly everyone with go pros etc who braved the sea, keeping very close to the boat, didn't catch any images at all. Sure you can see them when you move your hand through the water, but you can't get any pics. This was the main reason we travelled so far to take this trip so we were massively disappointed. If I'd stayed in Krabi, it would be a trip I would take, but not for the plankton for the islands...

HORRIBLE EXPERIENCE DON’T DO IT - HORRIBLE TOUR people not organised, they don’t do what written, very bad tour the plancton is not like in the picture. It’s a scam the whole tour
