No Kangaroo Island holiday would be complete without a trek to one of the island's signature landmarks, Remarkable Rocks. It took 500 million years for rain, wind, and pounding waves to create these aptly named granite boulders which are now part of the Flinders Chase National Park. Early morning and early evening are the most ideal times to visit Kangaroo Island Remarkable Rocks, not only to avoid large crowds, but also to enjoy the stunning sunrises and sunsets around these impressive sculptures. Many of the rocks are covered by golden orange lichen, and interpretation signs describe even more details about the formation of the rocks.

Black mica, bluish quartz, and pinkish feldspar comprise most of the granite of Remarkable Rocks. These flat rocks are easy and safe to walk on during dry weather, but special caution should be taken when weather conditions become wet or windy. Strong winds and slippery rocks make it far easier to fall into the water. The wooden boardwalk leading to the Remarkable Rocks is partially accessible for disabled visitors. The crest's western platform provides an ideal vantage point to see the surrounding bays and the historic Cape Du Couedic Lighthouse. The equally photogenic Casuarina Islets can also be easily seen from the Kangaroo Island Remarkable Rocks.

The Flinders Chase National Park is also home to another distinct Kangaroo Island landmark, Admirals Arch, a New Zealand fur seal colony, and the Cape Borda Lightstation. Cape Borda is the nation's only square lighthouse in addition to South Australia's tallest lighthouse.
