Meet the site
The Fireplace is on the eastern side of Duncombe Bay on Norfolk's north coast and takes its name from distinct rock formations. Oceanatik describes shore-entry diving to 20 m with visibility of 10–30 m, vibrant coral and abundant marine life, and notes that the water around the rock structures is calmer than directly along them. It rates the site for experienced divers.
The formations presumably resemble a fireplace or hearth – a common kind of name on Norfolk's volcanic coast, where erosion carves arches, chimneys and alcoves into the basalt. Rock formations that reach the surface create surge and turbulence close in, which is why the calmer water is around rather than on them, and why the site is rated for experienced divers.
The surrounding reef has coral cover and the fish typical of the north coast. Oceanatik does not list species, but Norfolk's reef fauna includes butterflyfish, wrasse, parrotfish, anemonefish, sweep, groper, morwong, rock cod, moray eels and emperors, with kingfish and trevally around structures and turtles regularly seen.
The north coast is in the lee of the prevailing south-east trades, so the Fireplace is often diveable when the south coast is rough, but it closes in northerly swell. Oceanatik lists it as a shore entry, although reaching the eastern side of Duncombe Bay on foot with gear is not straightforward and a boat from Cascade Pier is the practical option. The exact position is not published; the coordinates here are approximate. It suits Advanced divers who are comfortable near surging rock.
