Completed my Open water diver course here with Joe and Ryan. Though the whole team was great, really friendly, informative and patient. Joe was fantastic and made me feel really comfortable underwater, can't thank him enough. If I decide to do more advanced programmes it'll probably be with these guys, can't recommend them enough!! ❤️
The Freediving course is awesome, Such an amazing experience! Titou is a very mindful, respectful and funny instructor, we enjoyed every session a lot! Thanks🙏🫶

Hugo thanks to Lydia , Zack, and Andreas for an unforgettable day of diving! You were amazing — patient, professional, and so much fun! We felt safe and well taken care of the whole time, and our kids absolutely loved the experience. It was the perfect introduction to scuba diving for the whole family. Highly recommended!
I have done my first 2 recreational dives with Goodtime Adventures after passing my open water certification. Extremely profesional and friendly atmosphere. Thank you Andrea for being my guide for such an amazing experience.
I had a wonderful try dive and couldn’t have asked for a better first experience. My instructor, Ana, was incredibly patient, calm and supportive, explaining everything step by step and helping me feel confident underwater. Same for Andrea, great instructor 💪. Thank you so much for your professionalism and positive energy — it was a beautiful experience!
