    I was quite anxious because I was alone and had not been diving for a long time. However, the staff was very friendly and relaxed me immediately with their detailed explanations. The clarity of the water was outstanding, and the loneliness of being surrounded by fish was a wonderful experience that blew away any sense of isolation.
