Hans Hass Place is on the outer reef of North Male' Atoll facing south into Vaadhoo Channel. It is an area about 100m long set back in a large recess in the reef. The reef top is at about 3m and drops vertically to a line of over-hangs at 8-10m. The western end is marked by a large cavern at 10-15m. There are further overhangs at 20-25m. Hans Hass Place is named in honour of the great pioneer of diving in Maldives Small delicate purple sea fans cover the ceilings of the overhangs and in the caves are many species of groupers, immaculate soldier fish and shadow-fin soldier fish. Commonly seen on this reef are the scribbled filefish, trumpet fish and the freckled hawk fish
