About this site
Deep Grambonissi offers dramatic underwater cliffs and caves in the clear Aegean. The site features steep drop-offs covered in vibrant sponges and gorgonians. Schools of barracuda and groupers patrol the blue, while moray eels hide in crevices. Strong currents attract pelagic life, making it ideal for advanced divers. Visibility often exceeds 30 meters, with water temperatures ranging from 18-26°C. The rocky outcrops create swim-throughs and overhangs teeming with marine life. Best dived in calm conditions due to exposure.
