The Blue Hole is an inland sinkhole created by the collapse of a limestone cavern ceiling.
It is connected to the open sea via a natural archway located 7 meters below the water's surface.
The site remains a globally recognized destination for cave and cavern diving despite the 2017 collapse of the adjacent Azure Window.
The surrounding Dwejra area is a protected Natura 2000 site due to its unique geological and biological features.
The limestone bedrock surrounding the hole contains fossilized remains of marine creatures from the Globigerina Limestone period.
Blue Hole Viewpoint offers a vantage point overlooking one of Malta's premier scuba diving sites, located on the western coast of Gozo near Dwejra Bay. The site is named for a natural limestone sinkhole measuring approximately 15 meters deep and 10 meters wide, connected to the open sea by an underwater archway. The terrain consists of rugged, karst limestone landscape shaped by erosion. It is positioned adjacent to the remains of the former Azure Window geological formation. The area serves as a primary hub for technical and recreational divers exploring the Mediterranean seabed. Visitors can observe the geological transition from inland rock formations to the marine environment. The surrounding shoreline is characterized by rocky outcrops rather than sandy beaches.
The elevated rocky ridge overlooking the sinkhole provides a clear aerial perspective of the circular formation.
Wear sturdy, closed-toe footwear to navigate the uneven and sharp limestone terrain.
Bring polarized sunglasses to better see through the water's surface reflections.
Visit during calm sea conditions, as heavy swells can make the surrounding rocks dangerous to traverse.
Attempting to swim or jump into the Blue Hole without appropriate diving training and equipment.
Avoid walking on fragile rock formations to prevent erosion; follow standard conservation practices for protected areas.
