The Grotto is a rock formation in Victoria that attracts many tourists. It is a combination of a cave, sinkhole, and archway. Waves and winds have eroded the rocks for centuries. The outcome is a caved sinkhole within the limestone cliffs.
The site is part of Great Ocean Road trip. It’s free to visit all year. You can see it from the viewing platform above and learn about the landscape from informational panels. From sea level, you can look through the archway and see the smooth rock pools inside. The calm, clear water in the limestone pools contrasts with the ocean’s crashing waves.
The process of how The Grotto was formed
The Grotto was formed over a long period through erosion caused by wind and ocean, resulting in a window that overlooks a Sinkhole.
The sandstone and limestone cliffs were formed over 20 million years ago at the bottom of a deep ocean. This occurred due to the pressure from the water compacting various substances, including fish, plants, sand from rivers, and other ocean debris. Limestone is essentially Sandstone with more than 50% fossil content.
The ocean has undergone multiple changes in water level over the past 20 million years, eventually settling at its current level approximately 6,000 years following the Ice Age.
After the formation of the Sandstone, rainwater infiltrated the cracks, creating subterranean rivers. Over time, erosion caused by these underground rivers led to the collapse of a portion of the stone’s roof, forming a sizable sinkhole.
The formation of the Grotto resulted from the sinkhole and the erosion of the cliffs caused by the ocean and wind.
