The Underwater Scenery

Santorini’s volcanic caldera offers a distinctive underwater landscape. Although the reef isn’t described as vast, it’s packed with vibrant marine life. Reviewers have spotted small fish, rascasse (a type of scorpionfish), and coral, making each dive a lively, colorful experience. Water clarity is often praised, offering good visibility—important for first-time divers who want to see what’s beneath the surface without feeling overwhelmed.

Because the dive is guided, you’ll have plenty of support, and the instructor will be nearby, providing reassurance and answering questions. As Khai_T observed, the extra instructor following underwater made the dive feel safe and secure.
