Kangaroo Island is home to a haven of natural wonders, but by far one of the greatest is the Remarkable Rocks.

Known as the island’s best-loved natural landmark, this massive rock formation is a special part of the landscape-being apart of the island for over 500 million years.

The Formation of the Remarkable Rocks

Remarkable Rocks

The rocks sit right alongside the coastal clifftop of Kangaroo Island, featuring a series of massive rocks that range in both size and shapes. From sharp points to smooth edges, the rocks are completely unique and all created through the natural formation of erosion. Intricately carved by both the continuous wind, rain, and nearby sea salt, these rocks have undergone 500 million years of slow erosion. The rock material is known as an Ordovician granite, with the material coming from the splitting of the supercontinent Gondwana, which was made up of Australia, South America, Africa, India, and Antarctica. Once the supercontinent began to split up, Australia and Kangaroo Island began moving northward, with the Ordovician granite sitting along the edge of the spilt.

Why you should see them

The collection of gigantic, eroded granite boulders is truly a sight to see. Creating one of the most unique silhouettes against the crashing sea and landscape. The rocks are perched 200 feet above the sea, nestled on the clifftop of the stunning Flinders Chase National park. Visitors can wander through the collection of these rocks, stepping into the gigantic, hollow granite boulders or around the sharp picks, marvelling at the size and the complete individuality these natural formations hold. One of the other reasons for the rock’s popularity is due to their colour. Due to the materials within the rock material, over time, the outer layer of the boulders have rusted. Turning the majority of the stones into large orange rocks, which contrast beautifully with the nearby greenery and sapphire ocean.

When to see them

Although you can see these rocks at every hour of every day, the very best time to view them is during the sunrise or sunset. Due to the bright orange lichen lighting up to the extreme when the sun moves across the horizon. Enhancing the colour and the surrounds even further, and making for the ideal photo opportunity for visitors, with the entire region and rocks turning a vibrant gold.
