The basalt pillars were created approximately 270 million years ago.
The rocks are composed of Kiama Latite, a specific type of volcanic rock found throughout the Illawarra region.
The site is a known location for observing migrating whales between May and November.
The erosional processes at this location are active, constantly reshaping the stack structures.
Cathedral Rocks are prominent volcanic sea stacks situated at the northern end of Jones Beach in Kiama Downs, New South Wales. The geological formations consist of Permian-aged volcanic rock, specifically latite, which has been weathered by Pacific Ocean currents. The vertical basalt columns exhibit unique jointing patterns formed during the cooling process of lava flows. The site is a primary location for sunrise photography due to the eastern orientation of the cliff face and stacks. Visitors can access the rocks via a coastal trail connected to the headland at the end of Cliff Drive. The area is part of the broader Minnamurra Bends region, known for its distinctive coastal geology.

Wear sturdy footwear with high grip as the volcanic rock is uneven and often slippery.
Bring a polarizing filter if you plan to photograph the water to minimize glare on the wet rock surfaces.
Check local tide charts, as high tide can significantly limit access to the base of the stacks.
Attempting to walk out to the stacks during incoming high tide, as waves can surge unexpectedly.
Stay behind safety fencing on the cliff tops; do not climb the stacks as the rock can be unstable.
