Along Victoria’s rugged southern coastline lies a natural wonder that looks almost like it belongs in a fantasy landscape. Rising from the waters near Wilsons Promontory National Park, Skull Rock Victoria is one of Australia’s most unusual geological formations — a giant granite island with a massive sea cave carved through its centre.
Officially known as Cleft Island, the landmark earned its famous nickname because the enormous opening in the rock resembles the shape of a human skull when viewed from the right angle. Created over millions of years by powerful natural forces, Skull Rock has become one of Victoria’s most fascinating coastal attractions, attracting photographers, nature lovers and adventure travellers.
Unlike many famous landmarks that can be reached by road or walking tracks, Skull Rock remains a mysterious offshore destination. Visitors usually experience it from the water on boat tours departing from areas around Wilsons Promontory, making the journey itself part of the adventure.
Where Is Skull Rock Victoria Located?
Skull Rock is located in the Anser Group of islands, offshore from Wilsons Promontory in Gippsland, Victoria.
The area is part of the protected Wilsons Promontory Marine National Park, a region known for dramatic coastal landscapes, rich marine ecosystems and unique geological features.
Wilsons Promontory, often called “The Prom” by locals, is one of Victoria’s most treasured natural areas. It is famous for:
- Pristine beaches
- Granite mountains
- Coastal walking trails
- Native wildlife
- Marine environments
- Scenic islands
Skull Rock sits among these remarkable landscapes, offering visitors a rare view of Victoria’s offshore wilderness.
Why Is It Called Skull Rock?
The name “Skull Rock” comes from the island’s extraordinary appearance.
From certain viewpoints, the huge cave opening creates the illusion of:
- Eye sockets
- A hollow skull shape
- A dramatic natural face carved into stone
The effect is especially noticeable when viewed from the sea, where the opening cuts through the granite island and creates a powerful silhouette.
However, the formation is not the result of human activity. It is entirely natural, shaped slowly by geological processes over millions of years.
The Geological Story Behind Skull Rock
Skull Rock is a remarkable example of coastal erosion and the power of nature.
The island is made from granite, a hard rock formed deep beneath the Earth’s surface millions of years ago. Over time, geological changes exposed the granite, and natural forces began reshaping it.
The massive cave was formed through a combination of:
- Wave erosion
- Wind exposure
- Weathering
- Changing sea levels
- Natural fractures in the rock
For thousands of years, waves repeatedly struck the weaker sections of the granite. Gradually, the opening expanded into the enormous cavern visible today.
The result is a spectacular example of how landscapes evolve over geological time.
The Size and Scale of Skull Rock
One of the most impressive aspects of Skull Rock is its enormous size.
The island is approximately:
- 300 metres long
- 200 metres wide
Its central sea cave is even more impressive, measuring approximately:
- 130 metres wide
- 60 metres high
Standing near the formation from the water gives visitors a true sense of scale. The cave is large enough to create a dramatic natural cathedral-like space inside the island.
Visiting Skull Rock: How Can You See It?
Because Skull Rock is located offshore and has difficult access, most visitors see it through guided boat tours.
These tours typically provide:
- Close views of Skull Rock

The boat journey around Wilsons Promontory is often considered just as memorable as the destination itself.

Photography Tips for Skull Rock

Capture Different Angles

Use Morning or Afternoon Light
Soft natural light can highlight the texture of the granite and make the cave appear more dramatic.
Include Scale
Adding a boat, person or nearby wildlife in the frame helps show the enormous size of the formation.
Respect the Environment
