Rocky wall dive in Marathon, Attica, Greece.
Local guide support is the practical way to handle access and conditions here.
Old quarry is a rocky wall dive in the Marathon area of Attica, best approached as a guided local dive. The site is appealing for its steep relief, clear east-Attica water, and compact Mediterranean profile, with good planning value for certified divers who want a short, focused dive rather than a casual beach stop. It works best on settled days when the sea is calm and the wall stays easy to read.
