When I was looking to book this trip I struggled finding any reviews for it. I got back yesterday so thought I would post a review for anyone interested.
Was picked up at hotel and on the boat by 7pm with about another 10 people. From there the boat headed for the Similans (about 5 hours) whilst we were shown around the boat and given dinner. The boat is fairly basic but I wasn't really expecting anything else so that was fine. There is a sun deck with bean bags for those wishing to sit up there, or sleep if the cabins were too hot.
Each day breakfast is at 7.30 and then it is usually followed by a snorkel or 2 before heading off. The first day proper was at the Similans. Getting there in the night meant that the first snorkel was before the day trippers arrived (a lot of them too). Saw some nice turtles there but the reef was pretty dead so just the usual reef fish too. Did another snorkel there afterwards at Donald Duck bay by which time the speedboats had arrives so it was off to Koh Bon, just over 2 hours. Again the reef there wasn't great and didn't see anything too exciting. If you are lucky though this is the place to see the Mantas. It was then off to Koh Tachai where we were to stop for the night. Before that though we went to the beach for a drink and a quick climb up the hill to see the sunset at the other side of the island. Tachai beach was incredible, one of the best I have seen. It was like walking on flour. Saw a couple of baby sharks in the shallow water off the beach too. Next day again was a snorkel after breakfast, slightly better than the other 2 places. Then it was off to the Surin Islands, I think about 3 hours. Once there we visited the sea gypsy village which was nice and then took a trip to a other bay where there were mangroves. For me this was the highlight, if you stand still here you will have loads of baby sharks swimming round your legs. An amazing experience. Later there was another snorkel followed by 2 the next morning. The Surins were by far the best, saw cuttlefish fish, moray eel, sea horses, clownfish, sea snakes and the usual array of reef fish. The coral here was in much better condition.
It was then. Time to head back.
I really had a great time on the boat. Ralf who runs the trip is very knowledgeable and also a great character (although his taste in music is somewhat suspect - Bavarian Reggae???) the crew were all lovely too and the food was very good and quite varied. They even cooked special dishes for the 2 vegetarians.
If you want to visit these islands don't do a daytrip with the hoardes, go with these guys, you won't regret it and Ralf will make sure you see the best of what they have to offer and you will have a great time along the way.
