The people at Goodtime Adventures are not only incredibly knowledgeable about the world of diving but also so warm and welcoming, and it was for those reasons that I signed up with them for my Open Water Course! Lydia was an amazing instructor - an expert at breaking down learning materials into clear concepts and giving helpful feedback so that I could improve as a diver. She was so encouraging and ultimately helped me gain the confidence to become a competent diver and I’m so thankful!! Next time I’m coming to Koh Tao I’m definitely having more adventures with Goodtime. Thanks yall for some amazing memories!

Amazing experience! It was my first dive and Anna made me feel very familiar and trust her. Everything went perfectly and I look forward to the next time 🙏🏼

100% recommend! Just finished my Basic Diving course with Lydia as my instructor. She was patient, alert and gave good feedback but more than that she was clearly passionate about it and it was contagious. I couldn't have asked for more as my first dive ever! We were able to see a lot of different fish and overal enjoyed the experience a lot. Thanks, I had a good time 🤙

Good Time Adventures is absolutely amazing! We completed our Open Water course here with our wonderful instructor Ana. Thank you, Ana! She made us feel safe, confident, and comfortable from start to finish. A big thank you as well to Lydia for her support and kindness. We were also lucky to have Beth take stunning photos of our dive experience. If she’s around, I highly recommend getting your pictures taken by her. She is really a professional and captures every moment beautifully, making the whole diving adventure even more special and giving you amazing memories to look back on afterwards. Thank you, Beth, for capturing these moments 🤍 Take a look at a few pictures yourself!
