Organ Pipes National Park

A set of basalt columns as straight and regular as organ pipes is the central feature of this 121 ha park, set in a deep gorge in the bare Keilor plains. There are other rock phenomena and the park is worth visiting for its native vegetation and variety of birds. Things to do * The park is an excellent place for picnics, walks, bird observing and photography. * Stand on the viewing platform - the basalt Keilor Plains all around you are part of one of the world's largest lava flows. * Walk down the path to view the 'organ pipes' - a set of basalt columns formed by lava. * Look for yellowish sandstones and mudstones across the creek 200 metres downstream from the 'organ pipes'. * Fossils in these rocks suggest they are sedimentary rocks laid down under the sea about 400 million years ago. * Walk upstream about 400 metres past the 'organ pipes' and see Rosette Rock - a radial array of basalt columns like the spokes of a wheel. * Look at the Tessellated Pavement, the tops of basalt columns. * Enjoy a picnic while looking out for waterbirds, blue wrens, cockatoos, rosellas, magpies and wedge-tailed eagles.
