       Lovely diving experience with the amazing team at Alien Divers. Our group had a few 50-60 year olds diving for the first time, and the crew was super helpful and supportive. Special shout out to Prab, Khun Dej, Hi, Gary, Phet and Phillipe for all their help in making this a memorable experience for us.

     It was a wonderful diving day in January 2026. Private pickup from the hotel in a red classic Benz. Diving location was gorgeous.  Professional instructor, Khun Dej, had my safety as priority while enjoying the underwater world. I definitely recommend Alien Diver. Plan to return.

     Best scuba diving experience ever! It was truly one of the best days of my life. The instructors were amazing—professional, friendly, patient, and made me feel safe the whole time. A special thank you to Khun Dej, who was absolutely perfect. He was incredibly patient, very knowledgeable, and always helpful. His calm guidance made the experience unforgettable. I highly recommend Alien Divers Krabi to anyone wanting an incredible scuba diving adventure. Thank you for such an amazing day!

     I had an amazing experience with Alien Divers! From start to finish, everything was organized professionally, and the entire team made me feel safe and comfortable.
A special thank you to my dive instructors, Khun Dej and Prop. They were incredibly patient, knowledgeable, and taught me diving step by step with clear instructions, making it easy to learn and enjoy every moment underwater. Their professionalism and encouragement gave me a lot of confidence.
Even though it was raining in the morning, the team handled everything perfectly. Once we reached the dive site, the conditions were great, and the dives were smooth, safe, and unforgettable. The crew stayed positive throughout and made sure I had an excellent experience.
I truly appreciate the effort and dedication of the whole Alien Divers team. I would definitely recommend Alien Divers to anyone looking to learn scuba diving or enjoy fun dives. If you’re in the area, this is the company to choose!
