We didn't go swimming or diving, so we weren't sure if the water was clear. But as far as we saw on shore, the water quality in this area didn't feel very clear. We drove three hours to the island with our rented water motorcycle. Maybe it would be better to spend a day on the island. We could enjoy more here! The scenery here is so beautiful! I can't forget to see that meteor at sea! It's so beautiful! The Thai government is doing a great job in protecting the natural environment. This island and the neighbouring islands make up Ko Rang Marine National Park. The coral reefs of Ko Yak Lek are very beautiful. However, the disadvantage of this water is that it has a depth of more than 3 meters, so it is not the best place to dive. Ko Tao and Ko Lipe would be better. There are also many tourists who come here to swim (most of them wear life jackets to snorkel), large fish mostly hidden in coral reefs, only a few smaller fish can be found, but there are very few species. In fact, if you come in May, you can also go to Ko Mak and Ko Kuud. However, Ko Rang will also close from June to October. Early May to mid-May is the best time since the off-season is just beginning.
