Trip Planner: South Pacific / Australia / Victoria / Greater Melbourne / Keilor / Organ Pipes National Park
The Organ Pipes National Park, abbreviated as OPNP, is a national park located in the Central region of Victoria, Australia. The 121-hectare (300-acre) protected area was established with the focus on conservation of the native flora and fauna, and preservation of the geological features in the Jacksons Creek, a part of the Maribyrnong valley, north-west of Melbourne. It is situated in a deep gorge in the grassy, basalt Keilor Plains.It couldn't be easier to arrange your visit to Organ Pipes National Park and many more Keilor attractions: make an itinerary online using Inspirock's Keilor holiday planner.
Within Organ Pipes National Park, the valley walls of Jacksons Creek expose Pleistocene volcanic rocks of the New Volcanic Group. These 2.5 to 2.8 million year-old basalt lavas, commonly known as trap rock, fractured during cooling into vertically standing, hexagonal basalt columns. These columns are locally known as the "organ pipes" for which this park is named. Over the last one to two million years, the slow cutting by Jackson Creek of its valley down into the basaltic plains and through the underlying trap rock exposed these geological structures. The bottom of the valley of Jackson Creek also exposes a prehistoric buried creek valley, which is cut into 400 million year-old (Silurian) mudstones and sandstones. The bottom of this buried valley contains ancient creek gravel. Both the ancient river valley and the Silurian sedimentary rock lies buried beneath the basaltic volcanic rocks of the New Volcanic Group. Marine fossils found in the Silurian sedimentary rocks demonstrate that they accumulated beneath a prehistoric ocean.
A Friends' group, (the first in Australia) the "Friends of Organ Pipes" (FOOPS), comprising conservation activists to support the efforts of rehabilitation of the OPNP's indigenous flora and fauna, supplemented the work of the Victoria Park system under which the OPNP was declared a National Park. The park's importance to the whole region as a "center for education about the geology, flora and fauna of the Keilor Plains, and the restoration of degraded land" is important. With its inclusion in the IUCN Category III (Natural Monuments) of the United Nations' list of National Parks and Protected Areas, there is a greater recognition of the need to protect or preserve outstanding natural features.
Organ Pipes National Park reviews
I'm amazed by the rock formation that shapes like gigantic organ pipes, how amazing it that (a stunning viewing pleasure), which makes me appreciate nature even more. To me, the major attraction is.... more »
A short easy 30 minute drive from Melbourne CBD via the freeway, this is a lovely picnic spot. The natural rock feature is pretty impressive as is a short walk downhill from the car park. Free entry..... more »
A very underrated park. When you reach at those lava streaks at the bank, the tranquility will summon you. A day's time pass can be arranged. The river/creek at the bottom is wide and picturesque. And, very close by.
great facilities, good walk, picnic facilities and a fun family day out. Could do with a safer entrance and exit from the freeway tho.
