Had an amazing time at the end of January, 2015 doing my open water course followed by the advanced adventurer course at Big Blue! Petra was an amazing instructor. Would recommend Big Blue to anyone looking to dive wheather it's their first time or their 100th! This place has a great vibe, you feel welcomed right away, and it's great for meeting other travellers! Would highly suggest to anyone doing their open water that they continue to do their advanced part of the course it was my favourite part and well worth it!!
