Of all the attractions on Kangaroo Island, the Red Banks are not one of the more well-known ones. You're unlikely to discover them on your own, but if you follow the right road you'll find unique red cliffs different to any other section of the coastline around here. However, I have to admit, I expected bigger things than what I found.

That road is quite pretty
The attraction can be found along the southern rim of Nepean Bay, near the small town of American River, on the north coast of the island. No matter how close you get, you won't find signs, so you will need to know what you're looking for. In this case that means finding Flea Castle Road, off Red Banks Road and Point Morrison Road. At the end of the road, where the peters out, are the Red Banks.
There is absolutely no infrastructure at this attraction at all (which, until I saw the amazing boardwalk at
Seal Bay, I was starting to think was common). To get a look at the banks, you have to walk out on the narrow strip on top of this particular section of the cliff. Once out there, you just take a look either side and appreciate the sights (before you chicken out and go back to safety).

These are what you came here to see

The section you stand on isn't quite as open as this neighbour, but it did seem skinnier
One the one hand, Red Banks seems so rudimentary that it's hardly attraction at all (there is a track down to the water, but I didn't follow it). On the other and, it does reveal a different side to the island. I'd say it's one to do if you've got time to spare, otherwise there are probably better things to see.
Or perhaps it's one to see from the water instead. Head out on a boat for some fishing - this area of the Bay of Shoals has a big variety of fish, but is particularly good for whiting- and get a look from out there. Sunset is apparently particularly good.
