Bathurst Lighthouse, on the northern edge of Rottnest Island, was built in 1900 to support Wadjemup Lighthouse following the City of York shipping disaster in 1899, where 11 lives were lost. It is 20 metres high and in conjunction with Wadjemup and the Fremantle Lighthouse, creates a navigational triangle to guide skippers.

The reef structure surrounding Rottnest Island meant that the construction of two lighthouses was essential to assist vessels in navigating the channel between Fremantle and the island.

Located at one of the highest points on the island, visitors can see the lighthouse and the breathtaking views on offer, including the famous sunsets of Pinky Beach.
