Snug Cove is one of the most dramatic places on the Kangaroo Island coast: a small cove beneath cliffs about 200 m high on the north-west coast, east of Cape Borda. The Marine Life Network describes excellent wall diving, with underwater walls cut by gutters and ledges to 20 m and beyond.

The walls are the attraction. Rocky faces covered in sponges, sea whips and colourful encrusting life drop away into clear blue water, and the gutters and ledges shelter rock lobster, boarfish, magpie morwong and blue-throat wrasse, with cuttlefish tucked into crevices. Out in the water, yellowtail kingfish cruise the edge and western blue groper patrol the reef. The remoteness of the north-west coast means little fishing pressure and big fish.

History is next door: the Finnish-registered barque Fides was wrecked about 500 m west of the cove in 1860 (some sources say 1859) with the loss of most of her crew, and her remains lie broken up against the cliff in an underwater gully (see separate row). Snug Cove itself was also the landing for a small settlement and has had private tourism operations, and land access has varied over the years – which is why boat access is the reliable option.

Because the north coast is sheltered from the prevailing swell, Snug Cove is often diveable when the south and west coasts are not, but northerlies make it dangerous. It suits Advanced divers who enjoy wall dives and remote, uncrowded sites. Bring full cylinders from Kingscote and plan the day around the drive.

Take the SeaLink ferry from Cape Jervis to Penneshaw (45 min), then drive west via Kingscote and the North Coast Road; the western north-coast sites are 1-1.5 hours from Kingscote on partly unsealed roads (red dirt, corrugations). Snug Cove lies east of Cape Borda below very high cliffs; land access is by steep track and has historically been via private property, so most divers visit by boat from the north coast (e.g. launched at Stokes Bay or brought by a Kingscote operator). Check current access arrangements with local operators before planning a shore dive.

Kangaroo Island's north coast faces Investigator Strait and is sheltered from the prevailing south-westerly Southern Ocean swell, so it is the island's most reliable diving coast. It is exposed to northerly and north-westerly winds and swell, which bring surge, poor visibility and dangerous entries – dive on southerly to south-easterly winds or after a few days of southerlies. Summer and autumn have the most settled weather; winter fronts bring north-westerlies before they pass.

Visibility is often 10-20 m in good conditions. Mornings are calmer before sea breezes.

Drop onto the wall near the cove's headland, descend to 18-20 m along the gutters and ledges, then work back up the wall to shallower reef for a long safety stop. Combine with the Fides wreck site 500 m west on a second dive.
