London Bridge

London Bridge is an offshore limestone arch on the Shipwreck Coast in Port Campbell National Park. Its broad opening sits between the Southern Ocean and the mainland cliffs. It is also called London Arch, a name that fits the single offshore span left standing today.

The upper western platform is a short, sealed 150-metre return from the car park. The lower eastern platform adds a 300-metre return on a steep, uneven route, so it is the closer option for visitors comfortable with rougher footing. A marked accessible parking space is listed, though the sloping car park can still be difficult. The two views make this more than a photo from the roadside.

The formation once had two arches and a landward span joined to the coast. That inner span collapsed in January 1990, leaving two visitors stranded on the outer section until a police helicopter rescued them. The remnant became an island, and the familiar bridge name stuck even after the bridge itself was gone.

The pale cliffs and stacks are made from Port Campbell Limestone, deposited in marine conditions about 14 to 7 million years ago. Waves and weather later carved the cliffs and arches, undercutting softer layers below the harder limestone. The rock is still being worn away, so this is a view of a coast that keeps changing.

From the upper lookout, include some of the breaking surf or mainland cliff with the arch. That gives the offshore span a sense of scale and shows the gap that separates it from shore. Visitors often favor sunset for warmer color across the limestone, but the waves and arch are the reason to stop.
