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!! ❤️

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.
