great stuff. Weather conditions made it impossible to visit the cave but we still had a great time snorkelling nonetheless. Guide was great fun.

Me and my sister booked a day adventure which included Canoeing in the Mangroves and snorkelling at The Blue Cave. Our guides were Makoto and Aoe they were both amazing, very friendly and made our experience very memorable. They were easy talk too, and created a very welcoming and inclusive atmosphere to all groups of people. Thank you for helping me and my sister make beautiful memories that we will treasure forever!

The experience was fantastic! Our coach, KAK, was handsome, provided excellent service, and seamlessly switched between Chinese, English, and American languages, which made us feel very safe! Highly recommended!!!
