London Bridge: The Famous Rock Formation That Collapsed
Located within Port Campbell National Park, London Bridge, also known as London Arch, is one of the most recognizable natural landmarks along Victoria's Great Ocean Road. This impressive limestone formation stands offshore, surrounded by rugged coastal cliffs and the powerful waves of the Southern Ocean. Situated just west of Port Campbell, London Bridge is famous for its unusual shape and the dramatic collapse that changed its appearance in 1990. Today, visitors can admire the remaining natural arch from scenic clifftop lookouts while exploring one of the most fascinating sections of the Shipwreck Coast.
The History of London Bridge
London Bridge was originally a double-span limestone formation connected to the mainland by two natural arches. Its unusual shape resembled a bridge extending out into the ocean, giving the landmark its name. On 15 January 1990, the section closest to the mainland unexpectedly collapsed into the Southern Ocean, leaving the outer arch completely separated from the coastline. Two visitors were standing on the outer section when the collapse occurred. With their path back to the mainland destroyed, they became stranded on the isolated rock formation until they were safely rescued by helicopter. The dramatic incident attracted international attention and highlighted the constantly changing nature of the Great Ocean Road's limestone coastline. Following the collapse, the formation became known as London Arch, although many visitors still refer to it by its original name, London Bridge.
How Was London Bridge Formed?
Like the nearby Twelve Apostles, London Bridge was created through millions of years of coastal erosion. The limestone cliffs along this section of the Great Ocean Road were gradually shaped by the combined forces of ocean waves, wind and rain. Waves repeatedly struck the base of the cliffs, wearing away softer sections of limestone and creating caves. Over time, these caves expanded into natural arches, eventually forming the distinctive double-span structure. The collapse in 1990 demonstrated how erosion continues to reshape the coastline. Today, the remaining arch stands offshore, with waves passing through the opening beneath the rock. This ongoing geological process means the appearance of London Bridge will continue to change over time.
London Bridge Lookouts and Viewing Platforms
London Bridge features several designated viewing areas overlooking the limestone arch and surrounding coastline.
Upper Viewing Platform
The upper western viewing platform provides panoramic views of London Arch, the surrounding cliffs and the Southern Ocean. A sealed pathway leads from the car park to the viewing area, making this the most accessible option for visitors. The return walk is approximately 150 metres.
Lower Viewing Platform
The lower eastern viewing platform provides a different perspective of the formation, allowing visitors to appreciate the size of the remaining arch and the gap created by the 1990 collapse. The return walk is approximately 300 metres and includes a steeper, uneven pathway. It is not suitable for wheelchairs, prams or visitors with limited mobility. Both viewing areas offer excellent photography opportunities, particularly when ocean waves break against the limestone cliffs.
Wildlife at London Bridge
In addition to its spectacular coastal scenery, London Bridge is an interesting location for wildlife spotting. A colony of Little Penguins nests along the protected beach beneath the lookout. Around dusk, visitors may be fortunate enough to see penguins returning to shore after spending the day feeding at sea. Penguin sightings are not guaranteed, and visitors should remain on the designated viewing platforms to avoid disturbing the wildlife. During winter, Southern Right Whales and Humpback Whales may also be spotted offshore as they migrate along Australia's southern coastline. Visitors should keep an eye on the ocean for signs of whales, particularly between June and September.
Best Time to Visit London Bridge
London Bridge is a spectacular attraction throughout the year, with changing weather and ocean conditions creating different views of the coastline. Early morning often provides softer light and fewer visitors, making it an excellent time for photography. Late afternoon and sunset are also popular, when warm sunlight highlights the golden limestone cliffs and surrounding rock formations. During winter, larger ocean swells and dramatic skies can make the coastline particularly impressive. This is also a good time to watch for migrating whales. Visitors hoping to see Little Penguins should plan to visit around dusk, although wildlife sightings depend on natural conditions. Strong coastal winds can occur throughout the year, so bringing a warm jacket is recommended.
Getting There
London Bridge is located along London Bridge Road near Peterborough, approximately seven kilometres west of Port Campbell. Visitors travelling along the Great Ocean Road can follow the signs to London Bridge and use the designated car park. From the parking area, short walking paths lead to the upper and lower viewing platforms. London Bridge is a convenient stop when travelling between Port Campbell and Peterborough, particularly for visitors exploring the nearby coastal attractions. Allow approximately 15–30 minutes to enjoy the lookouts, take photographs and learn about the history of the formation.
