About Santorini Caldera Marine Protected Area

The Santorini Caldera Marine Protected Area safeguards the iconic underwater volcanic caldera of Santorini, rich in unique marine biodiversity and geological features, offering exceptional diving and snorkeling experiences.

Wilderness Landscape & Natural Heritage

The Santorini Caldera Marine Protected Area encompasses the submerged volcanic caldera created by the massive Minoan eruption approximately 3,600 years ago. Located in the South Aegean Sea around the island of Santorini, Greece, this protected zone covers the dramatic underwater cliffs and geothermal vents that define the caldera's structure. The area is renowned for its vibrant marine ecosystems, including rare Mediterranean species like large groupers, colorful sponges, and endemic corals, thriving alongside hydrothermal vent communities sustained by underwater volcanic activity. This combination of geological wonder and rich ecology makes the Caldera a hotspot for marine research and eco-tourism. Recreational activities revolve largely around scuba diving, snorkeling, and boat tours — allowing visitors to explore volcanic formations, underwater caves, and thermal springs that heat the surrounding waters. Surface vantage points on Santorini’s clifftop villages offer breathtaking views of the caldera’s expansive water basin. Historically, the caldera’s massive eruption shaped not only the island’s dramatic landscape but also local culture and mythology. Visitors are drawn by its natural beauty, geological significance, and vibrant aquatic life. The Marine Protected Area aims to conserve this fragile underwater environment amidst growing tourism pressure and climate change impacts. With careful management, the Santorini Caldera remains a unique destination for marine enthusiasts and those seeking an extraordinary encounter with volcanic seascapes and Mediterranean biodiversity.
