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!

Enjoyed underwater with Khundej . Great dive instruction and went up to 9 metres. One of my first PADI beginner dives. Must go in Krabi with these guys . My wife and I thoroughly enjoyed 1*1 instruction from the team.

An unforgettable scuba diving experience with Alien Diver! I joined the Discover Scuba Diving program with my 11-year-old son, and it was one of the best experiences we’ve had together. From the very beginning, the owner made us feel welcome with his kindness, professionalism, and genuine care. Being a local operator, he gave us honest advice about the current season in Krabi and suggested the best timing and safest location for our dive. What impressed me most was their commitment to safety. Normally, we would have had one instructor for both of us, but without charging us extra, they provided one instructor for me and another dedicated instructor for my son. Knowing that my son had a professional instructor focused entirely on him gave me complete peace of mind and allowed us both to enjoy the experience to the fullest. The dive site was close and carefully chosen, making it ideal and safe for a family experience. Underwater, we saw beautiful fish, colorful corals, and an amazing marine environment that made our first diving experience truly magical. We also had time to snorkel, which made the trip even more enjoyable. The atmosphere was wonderful—far from the crowded tourist operations. The local boat, local owners, and friendly team added a special charm and authenticity that made the whole day feel personal and memorable. The prices were extremely fair and offered excellent value, especially considering the extra attention, safety, and care we received. It is rare to find a company that combines professionalism, kindness, safety, and great pricing so well. A huge thank you to the owner and the entire Alien Diver team for giving my son and me such a special memory. We will never forget this experience and highly recommend Alien Diver to anyone visiting Krabi, especially families and first-time divers looking for a safe, enjoyable, and truly authentic diving adventure. Thank you from the bottom of our hearts!

Did our first ever scuba diving experience with Alien Divers and it was honestly an experience of a lifetime 🌊🐠 We got picked up from our hotel around 8:30 AM and dropped back after the tour, which made everything super smooth and stress free. After reaching their office, we tried on the wetsuits and got all the equipment ready before heading to the sea. We did 2 dives and even though the currents were quite high that day and the weather conditions weren’t the most beginner friendly, the whole team made us feel very safe and comfortable throughout. Huge thanks to instructor Khun Dej, he was incredibly patient, helpful and reassuring, especially since it was our first time scuba diving 🫶 The other crew members were also really kind and supportive. They also provided fruits and a packed lunch box during the trip which was a lovely touch 🍍✨ Overall, such a memorable experience and we had an amazing time. Would definitely recommend for anyone wanting to try scuba diving in Krabi 🤍
