Starting from Henderson Avenue, Rottnest Island, this walk takes you to Oliver Hill, visiting numerous historical relics, coastal and inland areas along the way. Expect views of open fields and panoramic coastal landscapes with informative signs along the Ngank Yira Bidi track. There is a sunken ship around picturesque Henrietta Rocks that can be observed while snorkelling and swimming. After you enjoy the turquoise waters, follow the path as it traverses inland sections. When you arrive at the beautiful Serpentine Salt Lake, you can observe the magnificent migratory and resident birds in the area. When you reach Oliver Hill, do not forget to take a look at the historic Word War II gun. Certain sections of the path can have an uneven texture. During the wet season, some sections of the walk can be inaccessible (seasonal beaches), so you might bypass these sections using roads. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
