Travelling around Thailand and the thing that scared me most was our pending scuba diving experience in Koh Tao. But from the moment we were on the ferry over, we felt so welcomed by all members of the Big Blue team. We completed the Open Water course and had such a good time that we couldn't possibly leave the island without doing the Advanced course. From not even being able to snorkel easily to diving through to 30m in the space of a week felt like a massive accomplishment. There really aren't words to describe the amazing feeling of diving, and I couldn't have asked for a better school to learn with. Our diving instructor Ernesto made me feel so at ease, explained things so simply, and really is a top guy! Had a great time and will recommend the school to everyone I know travelling to Thailand. Thanks!
