Perfect Tour to visit the Similian Islands

An amazing tour by Seastar company of the Similian Islands. Everything was planned and full day tour went smoothly. They offer 3 meals. Breakfast, lunch on one of the islands and dinner when you return back. Very friendly staff especially Sara, We and Gimp (not sure about the name ☺️) Boat 99. Staff also offers to take videos and photos for free to have memories with you back home. They give you all the snorkling equipment and offer drinks and towels on the boat. Wonderful experience for everyone. Highly Recommended

Extremely dangerous and irresponsible experience

This trip to the Similan Islands should never have taken place in these weather conditions. Before departure, we were told at the pier that the weather would be better and the waves smaller in open sea, which was completely untrue. It was clear that the organizers were mainly interested in our money. We repeatedly asked the guide, Chris, before departure whether the trip was sensible and, most importantly, safe. It had been raining in the days before, and although there was little wind, the sea in the harbor was already rough. After about 20 minutes, the conditions worsened rapidly. The wind picked up, the waves grew larger, and the young crew clearly underestimated the power of the sea and overestimated the boats. What started as excitement quickly turned into fear. People were vomiting and afraid for themselves and their children. At one point, a strong wave suddenly spun one of the speedboats in the opposite direction. Despite our clear requests to turn back, the crew refused and continued for another 15 minutes at high speed in extremely rough seas. One person suffered a serious panic attack that continued even after returning to shore. After about cca. 45 minutes, we were informed that the islands were closed due to bad weather — a decision that likely prevented a serious accident. Although we received a refund, this was the worst experience we had in Thailand. I strongly do not recommend this operator, especially for families or anyone expecting basic safety and responsibility.

Amazing Similan Islands Snorkeling Tour – Highly Recommended!

The tour was absolutely amazing! Our guides, Chris and Sunny, were truly fantastic. Chris is originally from Germany, which was a big plus for German-speaking guests, as everything was very easy to understand. Sunny was also excellent and very clear in English. The entire day was perfectly planned and organized. You are more than well taken care of when it comes to food — there is plenty to eat throughout the day. Snorkels and diving masks are provided on board, and everything is very hygienic since everyone receives a brand-new mouthpiece. Fins can be rented separately, and there are life jackets available for everyone on board. After arrival and group allocation, you head straight to the boat. The first stop includes snorkeling followed by lunch on the first island, which was really delicious. There are always drinks and snacks available on the boat, and towels are also provided for use during the trip. Before departure, you have the option to rent a GoPro for 1,500 Baht. Photos are taken throughout the day, and at the end you can purchase them for 200 Baht per photo, beautifully framed in a wooden frame — truly lovely souvenirs and memories. Hotel pick-up and drop-off were perfectly organized. We went in December 2025, which is high season, so there were many people, but it is still absolutely worth seeing the Similan Islands. After returning from the snorkeling tour, there is even a dinner before being brought back to the hotel. Thank you so much, Sunny and Chris — you gave us an unforgettable day that we will never forget!

Terrible mass tourism tour

The most horrible tour I've ever done. Absolute handling of mass tourism. The islands are very beautiful but full to the limit. There is garbage on the islands and no consideration is given to nature. The snorkel spots are besieged by 100 tourists next to each other. Bleached and dead corals everywhere. And the food was miserable, too. Absolutely not a recommendation. The rice/performance ratio is not given at all.

Trip of a Lifetime

This trip was an absolute delight from the very start to the very end. The organisation was impeccable, and the crew went above and beyond to ensure everyone’s safety and well-being. Our guide, Jennie, was an absolute gem—friendly, funny, and incredibly knowledgeable. We had an absolute blast every minute of it. The food was simply fantastic, considering the number of people they catered to on the island. They served delicious pasta, fresh prawns, and crispy fried chicken. There were an abundance of Coke and water, and even crackers and fresh fruit for our journey back to the dock. And to top it off, they had free ice cream, kebabs, and more treats waiting for us at the port on our return. The views were breathtaking, and the snorkelling was an absolute treat. We wish we could have stayed longer. Having booked a similar trip in Turkey last year, I wasn’t expecting much, but this trip far exceeded our expectations. It was not only more value for money but also better in every way.
