The Brainless Animal That Rules the Mediterranean
When we take you out to explore the crystal clear waters of Crete, your eyes are immediately drawn to the groupers hiding in the crevices, the playful octopuses, or the sea turtles crossing our dive group.

Stalactites and Stalagmites:
Stalactites and Stalagmites When entering a cave, silence is often the first thing that catches one's attention. The air is cool and damp. Then, the eyes adjust to the darkness and gradually discover a fascinating landscape: rocky points hanging from the ceiling, others that seem to grow from the ground, sometimes even meeting to form immense columns. One might believe it to be the work of a sculptor. Yet, these extraordinary shapes are the result of a surprisingly simple nat
