THE DIVING CENTER ARGONAUTA (5 stars Padi IDC Center S-9538) operates on the east coast of Sardinia at Cala Gonone, an enchanting, unspoilt coastal village which provides a perfect base to explore the scenic treasures around. Cala Gonone looks out onto the Gulf of Orosei, a Marine oasis inside the Gennargentu National Park, known world-wide for its limestone cliffs which stretch for 40 kilometres, furrowed by deep gorges and codule (dried-out riverbeds).

Cala Gonone is famous for the endless array of caves, tunnels and mysterious enclosures found near the surface of the sea. Many of these cavities have an above-ground portion that continues underwater.
