The diving was beautiful. Visibility of about 75 feet in the caldera. We dove Lions Head and The Porch(?). The Lions head really looked like a giant lions head. No imagination required. Lots of colorful fish at the reef - Porch. I would have liked to have dove the Caves outside of the Caldera but the winds were coming from the wrong direction and too strong. The crew was top notch. They handled everything beautifully. They were excellent assisting me when I struggled with my balance - inner ear problems. The dive master, who is from Barcelona, Spain originally, took the time to drive me through the traditional Greek Village on the way home. He also gave me recommendations on his favorite restaurant. Great out fit! Great dive master! I would absolutely use them again when diving Santorini.
