Blue Hole (Dwejra)

Gozo's signature topography dive. A rock chimney drops from the surface pool through an arch to the blue at around 15-25m, with the seabed near 30m. The Azure Window that once stood alongside collapsed in a March 2017 storm; its blocks now form part of the underwater terrain. Shallow near the entry, deeper past the arch.
