I had an amazing experience diving with this club! The instructors were really professional, patient, and made the whole experience fun and safe. The equipment was in great condition, and they were always available to answer any questions I had — both before and after the dives. Highly recommend this place to anyone looking for a quality diving experience. Thank you so much to Lukas and Lydia for everything! 🙏🌊🤿

I took a open water doving course with the guide Ana and had a great experience. Thanks to Ana I obtained confidence to dive and staying underwater became simple and enjoyable. So, I recommend everybody who wants to start diving to take this course at Goodtime!

Had a great dive with Beth as our DM on Sail Rock. She expertly navigated around and Mike took some great photos of us while we were underwater. Everything was professional and we had a fantastic experience!

Big up to Goodtime Adventure, I had such a great time doing my open water I continued and did advanced adventurer the following day! Ana was an excellent instructor and Luke was also a great buddy to dive with - felt like a great dive team, I learnt how to dive in their company. Whilst I had direct diving experience with Ana and Luke, it cant be stressed how great of a vibe it was on the Goodtime boat and how all the intructors on board were top professionals: Lucas, Lydia and Loris in particular! Thanks for the good time, Goodtime

Second time diving, but first time getting my OWC. I was pretty nervous at first but the people are super reassuring and help you out with whatever. Also didn’t feel like I was being sold a product rather they just offered a service. I went when it was a bit quieter which was super lucky since I got a lot of help from the instructors. All of them are really wonderful people (I hope I’m listing all of them). My instructor Loris in particular was awesome and helped me out constantly. The other instructors like Lukas, Luke, Lydia, and Ana all were super kind and attentive even if I wasn’t in their group. Thanks for everything
