Northern Arch

Northern Arch is the Poor Knights at their most vertiginous: a slot cut clean through the headland, walls sheer on both sides, the floor far enough down that clear water plays tricks on the depth gauge. In late summer short-tail stingrays assemble here, stacking in the arch in loose formations that can number dozens, with kingfish spiraling above them. Orca occasionally arrive to hunt the same rays, which empties the arch faster than any dive computer alarm. Even without the megafauna, drifting the walls among sponge and jewel-anemone color is a top-shelf dive; with them it becomes the story of the trip.

Момент, ради которого вы приехали: Stingray squadrons in summer, sheer walls through the headland, occasional hunting orca

Рельеф дна: A deep vertical slot through the headland, walls dropping to about 40 m

Течение: Flow funnels through the arch; crossing it can mean ducking into the lee of the walls.

Опасности: Depth deception in clear water and funneled current; plan the dive shallower than the arch invites.

Охрана природы: No-take reserve rules apply; give aggregating rays space and never block the arch ends.

Найтрокс: Здесь это оправдано: профили находятся в диапазоне, где обогащённый воздух реально увеличивает время без декомпрессии (при наличии соответствующей подготовки).
