The best way to explore the mysterious Arch Cave is on the Arch loop track. This easy walk starts and finishes at the Borenore picnic area, simply cross the footbridge from the picnic area and it’s just a short walk to the cave.

Take your time along the walk to check out the rock formations, they are quite striking close up and feature black, orange and yellow striped markings. Once you’re inside the caves, go slow to let your eyes adjust, or flick on your torch.

Look to the roof of the cave for the stalactites that cling tightly and to the stalagmites that grow upwards from the ground. Do you know what happens when the stalactites and stalagmites meet? They become a column; see how many you can count.

Spend as long as you like in the cave, from here, it’s just an easy walk back through woodland to the picnic area.

    Arch loop track is in Borenore Karst Conservation Reserve. Here are just some of the reasons why this park is special:

    Aboriginal connections

    The permanent flow of Boree creek and the reliable shelter of caves meant that this area was used for thousands of years by the Wiradyuri people. In fact, the name 'Borenore' is believed to be derived from two Wiradyuri words: bora which means ceremony and nora nora meaning shelf or overhanging rock. The reserve remains an important place for Aboriginal people today and protects a number of ancient sites, including Arch Cave which is highly significant for local Aboriginal women as a maternity site.

    From limestone to marble

    Marvel at the stalactites and stalagmites at Borenore Karst Conservation Reserve. The karst or limestone, as it is better known in the reserve, probably began life as limey mud and coral reefs some 390-400 million years ago when the area was located off the east coast of Australia. Around 12 million years ago, nearby Mount Canobolas spewed lava over the limestone, turning it into marble. Borenore marble, known as Borenore Red, was used in many public buildings in Sydney, including Transport House in Macquarie Street, and countless marble fireplaces.

A haven for birds, the park is home to thornbills, honeyeaters, kookaburras, magpies, treecreepers, weebills and more. Another special flying creature finding protection here is the eastern bent-winged bat, a threatened species that spends the winter hibernating in Tunnel Cave, before emerging in spring ready to migrate.
