I heard that there were fewer people in the Blue Cave in the morning, so I chose the 5:40 session. As expected, the early bird catches the worm. It was really worth choosing such an early session. There was no one at this time and the light was beautiful. I went out with my friend and directly booked the whole place. 😍 Brother Ashan is very professional and has a good understanding of the conditions of the Blue Cave. He is very humorous and considerate during the tour. He kept reminding us of precautions to prevent us from getting hurt (ex. be careful not to hit the reefs). The tour was very detailed, and we saw many creatures. The whole adventure experience was super good~ The camera was also very professional and took a lot of beautiful photos for us-- - - - - The intertidal zone tour is also recommended to everyone. Brother Shan took me to walk around the entire intertidal zone inside and out, looking for small creatures and plants on the beach along the way. These are things that I can't see when I'm wandering around by myself. It feels like an adventure and treasure hunt, which is super fun! ! Fortunately, we saw sea snakes that were supposed to live in the blue hole in the intertidal zone. The whole trip was worth it. I highly recommend it~👍🏻
