Had a great time diving with Ben at White Rock and Twins after helping the Goodtimes team do beach clean up! Ben was a great dive master and helped us identify a lot of cool fish and made it a super fun experience. Also huge shout out to Mike for joining our dive today and doing an awesome photo shoot for us!

My partner and I completed two fun dives with Goodtimes and had an amazing time! Our dive master, Ben, did a great job and made sure we had so much fun. Additionally, we also had Mike take photos of us and it was so much fun! Everyone was so friendly and we absolutely loved the vibes. We also joined the group clean-up earlier which was nice as it was sad to see so much trash around the beautiful island. We really enjoyed our day with Goodtimes and had so much more fun on the dives compared to our open water cert that we did with another shop. If you are thinking about diving here or getting a cert, I would recommend! If we had more time on Koh Tao we would come back.

Just Dive with Good Time 🤙 We did our Open Water with them. Such a lovely group of people that work here, especially our Instructor Lydia! She is so so good at what she does, she has a great way of teaching, really methodical in showing and explaining everything we needed to know to be safe divers. Lydia was patient too, and really made me feel at ease as someone who has a long-standing fear of drowning! If you’re in any way unsure of whether it’s for you, just talk to this crew and they’ll put your mind at ease and you absolutely won’t regret it! Owners are super sound and have created a lovely little community around it. Food is immense there too in their restaurant, lamb burger was outrageous. They often host international DJs, or an open decks sessions on a Sunday, so you can spend morning, afternoon and night perched there.

I recently did a refresher dive here after not having dived for several years. The instructors were friendly, patient and extremely knowledgeable. Highly recommend.
