Description: Scillion Caves sits below the dramatic sandstone headland known as The Skillion at Terrigal. This site features swim-throughs, small caverns, and sponge-covered rock faces. It’s a rewarding dive for experienced divers due to depth, surge, and navigation challenges. Access is usually via boat from Terrigal Haven or as an extended shore dive for advanced divers.
Marine Life: Home to wobbegongs, blue gropers, and schooling sweep. Nudibranchs and sponges coat the cave entrances. Divers often spot Port Jackson sharks resting in the sand gutters, moray eels, and the occasional kingfish passing by. In winter, giant cuttlefish display along the reef.
Hazards: Strong surge near the cave mouths in swell. Potential entanglement if entering tight sections. Watch for boat traffic above. Only suitable in calm seas.
Facilities: Access via Terrigal Haven with parking, toilets, showers, and air fills at Terrigal Dive Centre. Café and restaurant options on the foreshore.
