Visibility in the water is not the greatest. Interesting views, the boat trip was pleasant with light breakfast, and lunch provided. Coral disappointing but one must be aware that the marine park is not considered amongst the top ten in Thailand, never mind the the world.
We took the Samui Island Tour, but I would recommend one take the faster boats, for once your have visited the marine park, your return journey is much quicker. We started at 0730 from the hotel and returned by 1800 hrs which is a long day in the sun. Ensure you take 50+ sunscreen, hat, shoes to climb so can enjoy magnificent views, and shirt. Saw so many very red bodies, ouch
