What Our Guests Say
We particularly want to highlight the amazing snorkeling experience. It was a joy to see so many different types of colorful fish while observing the vibrant corals. We were even lucky enough to spot some large sea turtles!
The beaches and the sea are truly beautiful – like a paradise. We enjoyed the phenomenal natural scenery, and the overall nature within this national park is stunning. It was a memorable day and we highly recommend their services to anyone visiting the area.
During her first dive she experienced some panic attacks, but Aleks calmly reassured her, gave her time to relax, and returned to the water with her an hour later — and she succeeded. His teaching style is supportive, confidence-building, and truly top-notch.
After the course, we also completed two-tank dives with him in the Similan Islands, and the experience was fantastic from start to finish.
Thank you for teaching Rymma, Aleks — you did a fantastic job! We hope to dive with you again soon.
This is not the first we were diving with Aleks. Every time we get under the water with Aleks the feeling is the same that you will know you are in good hands. He is caring, considerate, patient, familiar with diving area. He took care of everyone not only in the water, but start from the pier, on the boat and after dive. You will feel safe, comfortable and built-up confident to dive with him.
And, this time we were doing the AOW course with him. We enjoy the time spend with him and bring us such a great memories. Thanks for showing us a glimpse of the best of under sea in the area.
It just can’t enough for saying. Simply go & dive with him. A great caring and encouraging Serbian Dive Instructor & Dive Guide.
Hvala puno.
We felt all of that while diving with Yu Dive Khao Lak and Aleksandar, our instructor.
Thank you, Sale, for your patience, experience and knowledge, which made it possible for me to relax completely and enjoy my own “underwater feature film.” I’m grateful to you for helping me push the boundaries of what I thought was possible once again!
See you next year!
We stayed on a liveaboard and were extremely satisfied: the equipment is new, the crew is always ready to help, and the accommodation and food are exceptional.
We also ventured into the jungle, slept in complete wilderness, and enjoyed all the beauty of untouched nature.
I wholeheartedly recommend YU Dive, especially to people from the former Yugoslavia, because sharing the language — and the mentality — makes the whole experience even better.
The preparation for each dive was concise and relevant. During diving he was very attentive, and he monitored us very closely, therefore I felt very safe at each moment. I would definitely recommend Saša as an experienced dive master. I plan to come to Saša’s diving school again and continue this amazing underwater journey.
He pays incredible attention to detail and always makes safety the top priority, which helped me feel completely comfortable throughout the entire course.
If you’re looking for a knowledgeable, professional, and genuinely supportive diving instructor, I can’t recommend Saša enough. Truly outstanding!
