Grotta - Istria Peninsula

Grotta, on Istria’s coast, isn’t about huge pelagics or endless reef walls. This site offers a different kind of charm, a subtle exploration. We’ve found it particularly good for macro lovers, with red snapping shrimp often seen waving their antennae from crevices and sunset cup corals adding bright splashes of orange to the darker areas. Keep an eye out for poor cod darting between rocks. While it might not blow you away with dramatic scenery, Grotta provides a calm dive, ideal for those who enjoy slowing down and appreciating the smaller details of the Adriatic.
