The water is insanely clear! I went on a kayak early in the morning and there were few people in the cave when we arrived. It was very pleasant to just chill and spend some time in the water but a big bunch of people were heading in as we were leaving. The guide also said that the cave can get super crowded during the day in peak season, where people have to queue to get in and out of the cave. Its not a big space and I imagine that will not be fun anymore so timing is key for best experience!
