    StandoutDramatic cave topography

    The Achata Arch offers a different kind of dive for the Dodecanese, focusing on an underwater archway and the light play within. It's a fairly simple exploration, good for divers who appreciate interesting rock formations over dense coral. You'll likely see smaller reef fish darting in and out of the shadows. We'd suggest it as a second dive, or for those looking for a relaxed photo opportunity.
