About Groupers Reef
Groupers Reef is a protected volcanic reef in front of Caldera Beach, set below the cliffs near Akrotiri. The terrain reflects Santorini’s lava geology, with reef structure and nearby wall and drop‑off scenery around the caldera. The site is known for rich marine life such as sponges, nudibranchs, groupers, snappers, barracuda, and schooling fish. Dives here are typically guided, and site plans can shift with weather and daily conditions.
