Nice excursion. - We were wild with the trip. However, we were very doubtful about the procedures before we left, but when we were picked up by the driver, everything was clear and clear.

Very well organised, entertaining and beautiful locations - This tour was truly a highlight of our trip! Our guide was incredibly knowledgeable and had such a great sense of humour, they kept us laughing all day. We were absolutely blown away by the beauty of the islands and the surrounding reefs, and seeing a turtle was an unforgettable bonus!

Very happy! - A well organized tour with Seastar. The catamaran was crowded and several boats departed at the same time as ours but still did not experience the tour as crowded. Many describe that it is “crowded”, of course you can not be alone on Similian, but there is plenty of space on the islands and you get a very lovely and dreamlike experience. It is incredibly beautiful, so worth experiencing! The snorkeling is good and the lunch good! Drinks and fruit are offered all day and the guides were skilled and safety conscious! Very happy with the tour, the whole family (our children are 4, 7 and 10 years old)

A day in the middle of nowhere. Not to be missed. - Wow! indeed. What an awesome day Mr Puu and the crew of boat 11 gave us. Even the storm during the first island visit didn’t spoil the day. The scenery is magnificent and the two snorkelling stops were absolutely amazing. So many different fish to watch in their natural habitats, and beautiful, unspoiled coral to wonder at. All this and food as well made for a day not to be missed.
