This is a very unique B&B which is totally self sufficient for power and water, but the lifestyle here is by no means impoverished. Our host David looked after us very well and accommodated us in well appointed and spacious bedrooms with private ensuites. Access is via a dirt road, easily navigable by conventional vehicles, but you need to be aware to not hit the many animals you will see on the road.
I would recommend that you bring some provisions for lunch and dinner, asking David for use of his kitchen, as he serves only breakfast. You also should use easily prepared food as power may be limited if it is cloudy and wind is still. The B&B has wifi internet, and 4G wireless and mobile phones have 2 bar reception across the strait from the Eyre Peninsula.
David is very proud of his property and took us on a guided walk down to the seashore observing plants and animals along the way. The coastline is spectacular from up on the clifftop as well as from down below.
Cape Cassini is on the north coast and central to the major attractions and facilities, although they all entail driving on dirt and paved roads. Easily at hand is Kingscote with its amenities, Stokes Bay and its beautiful beach and cafe, Seal Bay to view sea lions, and Flinders Chase with bushwalking, seals and natural features such as Remarkable Rocks and Admirals Arch. The beauty of Kangaroo Island is breathtaking and so much the better for the excellent base afforded by Cape Cassini Wilderness Retreat. We very much enjoyed our time and recommend it to anyone that enjoys looking after the environment and doesn't mind a slightly remote, but beautiful setting.
