Skull Rock is a huge granite island located off the coast of Wilsons Prom – here's how it formed (and how to see it)

Wilsons Prom is famous for its wild beaches, wombat-filled campgrounds and dramatic AF coastal scenery. But one of its most epic and cinematic sights sits just offshore: Skull Rock, a hulking granite formation that looks uncannily like a giant skull rising from the sea. Weathered by thousands of years of wind and waves, the rock has become one of the Prom’s most photographed natural landmarks – and a must-see for visitors exploring the southern edge of mainland Australia.
Skull Rock is a large offshore granite rock formation located near the southern tip of Wilsons Promontory. When viewed from the right angle, its hollowed sections and shadowed indentations resemble the eye sockets and nose cavity of a skull – hence the name.
Rising sharply out of the Bass Strait, the monolithic rock sits alone in the water and is part of the Wilsons Promontory Marine National Park, which protects the area’s marine life and rugged coastal landscapes.
Skull Rock lies just off the southern coast of Wilsons Promontory National Park in Victoria, about three hours’ drive southeast of Melbourne.
You’ll find it in Bass Strait near the southern tip of the Prom, beyond the park’s walking trails and beaches. Because it sits offshore, it isn’t accessible by foot and is best viewed from the water or from the air.
Like much of Wilsons Promontory, Skull Rock is made from granite that formed deep underground around 400 million years ago. Over time, tectonic uplift brought the rock to the surface, where it was slowly sculpted by coastal erosion.
Wind, waves and saltwater gradually carved out hollows and cracks in the granite, creating the skull-like shape we see today. The distinctive “eye sockets” are simply natural cavities formed as softer sections of rock weathered away faster than the surrounding stone.
Skull Rock is famous for its striking resemblance to a giant skull emerging from the ocean. From the right vantage point – especially at sunset – the shadows inside the cavities make the illusion even more dramatic.
The formation has also become a highlight of Wilsons Promontory boat tours and scenic flights, and it’s widely photographed thanks to its eerie shape and the wild coastal setting around it.
The best way to see Skull Rock is on a boat tour around the southern coastline of Wilsons Prom. These cruises travel through the marine park and pass close to the rock, offering the clearest view of its spooky skull-like features.
Another spectacular (and pretty spenny) option is a scenic flight from nearby towns like Yanakie or Foster, which gives you a bird’s-eye view of the rock surrounded by the deep blue waters of Bass Strait.
While you can’t reach Skull Rock directly by land, getting close to it starts with a trip to Wilsons Promontory National Park.
From Melbourne, drive about three hours southeast to the park entrance near Yanakie. From there, head to Tidal River – the park’s main hub – where many boat tours depart to explore the coastline and surrounding islands. Once you’re on the water, the dramatic silhouette of Skull Rock is impossible to miss.
