Unforgettable day - highly recommended! - Unforgettable day – highly recommended! We had a fantastic time on the SunSet Magic Snorkeling Tour around Koh Tao and to Koh Nangyuan – everything just fit perfectly! From the hotel pickup service throughout the day we felt super looked after and supported.  Snorkeling at several impressive spots was a real highlight – the corals and fish world around the islands are simply beautiful. The crew was friendly, professional and always attentive, and we even got underwater photos, which makes the memory of that day even more special. The lunch buffet on board was delicious and rich, and the BBQ dinner at sunset was the perfect end to the day – with breathtaking views and great atmosphere.  We especially loved the small, personal group (we were only nine people on board), which made the day cozy and relaxed – no comparison to crowded large boat tours.  💯 Top Tour, great team and a great success – we can highly recommend this experience to everyone!

Amazing Snorkeling & Sunset BBQ — A Perfect Day Out! - We had an absolutely fantastic day out with Zin and the Royal Mariblue Koh Tao team. The entire experience was memorable from start to finish. The boat is small and intimate, which made the trip feel personal and far more enjoyable than the larger, overcrowded tours on the island. The snorkeling was incredible, and the team went out of their way to capture amazing underwater photos for us. We also loved being able to enjoy SUP and kayaking during the day — such a great added bonus! Lunch was delicious, and the sunset BBQ dinner was the perfect way to end the day. It truly felt like a full-day experience that offered outstanding value for money. Thank you to Zin and the whole crew for the warm hospitality and for making it such a wonderful and unforgettable day. Highly recommended!

Super day between snorkeling and relaxation - Super recommended experience, boat that does not accommodate more than 20 people so small group with which you can better enjoy the whole day on the boat, excellent boat services. Super friendly and efficient crew, beautiful snorkeling tour managing to see the sharks and turtles. Recommended!

Small group, all inclusive - Fantastic full day of snorkeling! Very small group (3 on my day) so you are not one of the teeming masses like on other tours. Everything is included and taken care of. You pay more, obviously, but I’m so glad I prioritized the experience over expense.

It is truly magical! - We booked the VIP tour and it was worth it all - nice food and drinks, a small group in contrast to all the boats with dozens of people, but above all a very nice crew and snorkling guide who showed us beautiful corals, baby sharks and turtles next to all the other colourful sea life!

Best trip - This is the best trip you will book! Lucky our guide was absolutely brilliant, we saw every kind of fish, coral, huge turtles, baby sharks, the food and drink on board is exceptional, the transfer service punctual!!! Spend a little extra and go for this tour rather than the ones with too many people … this is the second time I’ve done this trip!!! Fantastic!!!

Good value tour but wildlife practices could be improved - Overall our experience was mostly positive though we do think the behaviour of the tour operators and guests around the wildlife could be improved. However this is not a critique unique to this tour operator as all tours we saw operating in each of the snorkel locations were doing the same things (detailed below) and could improve their practices around wildlife. We chose this trip as people who work with wildlife ourselves and wanted to try and see the wonderful marine life on Koh Tao, of which there is lots to see on this tour. However, the tour operators in their desire to get all guests the best look at, and pictures with the turtles and sharks, were often chasing them off and getting far too close, or allowing guests to damage the coral because they were taking people into shallower rough waters where people were not as confident swimming and would often kick coral with their fins. It would be far better practice to not take people into too shallow waters, and not allow them to chase or dive down towards these animals and we found that when we were separate from the group and did not do this, that the animals often came closer too us of their own accord. We think all the tour operators that we came across should enact these practices. Lastly we did notice that all snorkel mouthpieces seemed to be replaced after 1 use which seems an unnecessary waste of plastic. Otherwise, it was a very good value tour with 5/6 different snorkelling spots and lots of fish and wildlife to see, including turtles and reef sharks. The staff were friendly and the food served aboard was very tasty!

A great day of snorkelling! - A great value day and for the most part a very enjoyable one. We snorkelled in 5 different spots, and the food provided was excellent. The guides were also good and got some great underwater photos of everyone on the tour. However, as someone who works in conservation, there were a few niggles that are hard to look past. There was no briefing on how to behave in a coral reef or around wildlife, and I observed people from our boat standing on coral and not being at all careful with where they were putting their fins when swimming through reefs. It’s easy to forget your feet are a lot longer when wearing fins and some people could have done with a reminder of this. We were taken into a pretty shallow reef to see baby blacktip reef sharks which was challenging snorkelling conditions and something I don’t feel is well suited to beginners or inexperienced snorkellers. This could be improved by mandatory life jackets for that site specifically to help people feel more comfortable floating and keep them from knocking or standing on the corals and sponges. This takes me on to my second point. Particularly at Koh Nang Yuan, but in all sites where sharks were present, there was a disappointing amount of chasing occurring. This was not only by tour participants, but by guides as well, and this is a more general comment rather than specifically for this tour. Chasing any wildlife is stressful not only for the animal, but for the people caught up in the chaos of the chasing. Remaining calm and quiet will almost always result in better views, as those animals are always going to swim faster than any human can, and particularly so if they are swimming to get away from a crowd. A more relaxed observer means a more relaxed animal, it’s as simple as that. These sharks and turtles are wild, they don’t care if we get our photo or not and they don’t owe us anything. I understand that the guides want everyone to see the wildlife but chasing them is not the way to do it. Overall it was a brilliant day with some excellent snorkelling locations providing some equally excellent wildlife!
