About Grampians — Hollow Mountain

Hollow Mountain, at the northern end of the Grampians (Gariwerd) above the Hollow Mountain car park, was a popular steep climbing and bouldering venue before Parks Victoria's climbing restrictions. Hollow Mountain Cave is not on Parks Victoria's list of designated climbing areas, so climbing there is not permitted. The Gulgurn Manja rock-art shelter is next to the car park. Several designated areas nearby remain open, and this page keeps the weather for the area so you can plan a day at them: they share the same hard sandstone, which is brittle when wet.
