Great value for money.... - Great value for money. Some beaches were a bit crowded, but the tour was well organised. Nice food and highlight was sunset at the beach. For bio plankton I recommend jumping into the water when boat stops to swim as that’s when you can see so many of them!

Good day out - We had a great day going to different islands. I would recommend rock shoes for climbing the ladder in and out of the boat. Only 2 issues I have were the BBQ dinner was not a BBQ (deep fried chicken pieces, rice and chicken curry) and unless you get in the water you will not see the hi-light of the tour the Bioluminescence.

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.

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

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.

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.

Animal welfare issues - The tour itself was good and the tourguide also, but I would not book with this agency again. They had a big sign promoting elephant riding, which shows lack of insight and/or concern for animal welfare.
There were also three cats at the agency, of which two were pregntant, and the staff showed no understanding when I raised the topic of spay/neutering.
If animal welfare is something you care about, I would not book with this agency.

Poor boat trip - We booked this as part of a 7 island boat trip. It was very dissapointing to say the least. After a day of being hurded around like cattle with several other boat trips we saw some big rocks and some OK beaches. The last stop was to see the plankton light up at night in the sea. You saw more lights while lying on your back in the sea looking up at the stars!

Animal welfare issues - The tour itself and the tour guide were good but I would not recommend booking a tour with this agency. They had a poster to promote elephant riding, despite the known welfare issues of the elephants. There were also 3 unneutered cats at the agency location. 2 looked already pregnant. There was no interest in taking any responsibility to neuter them. I would not book a tour from this agency again until they remove elephant riding from their offering and stop promote that kind of tours. I think it is unprofessional.

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
