My wife and I are both Advanced Padi Open Water divers, but haven't done much diving since we started our family six years ago. As we planned our two week vacation on Tinos, diving was fairly high on our list of things to do. I searched the net and after some work I found Diving in Blue, in Tinos Town. I e-mailed the diveshop and after a swift reply and some e-mail correspondance we had a good contact there. Finding the diveshop is probably the hardest part as they are placed on the far side of the harbour in Tinos town.
We had two dives; one refresher and one "real". The equipment was all new, the service top notch and the divemaster was calm and trustworthy. I have dived in Greece before (Corfu) and I found Tinos to be better. Visibility +25 m, plenty of colour and fish.
