St Michaels Cave

St Michaels Cave is a sandstone formation at the northern headland of Avalon that extends considerably inland and features substantial vertical walls. The entrance opens broadly to the coast and forms a striking geological feature along this stretch of coastline.

A priest received this land through a grant in 1833 and planned to build a chapel either within or above the formation. This construction project was never completed, leaving the site in its natural state.

During the 1800s, families traveled by steamship to visit this place for social outings that included dancing, dining, and cave exploration. These visits were important community gatherings that attracted people from across the region.

Access to this location is restricted due to safety risks from unstable rocks and falling debris in the surrounding cliffs. Check current conditions and access rules before visiting to understand what areas are open to the public.

Inside the formation sits a volcanic rock intrusion that creates an interesting geological contrast within the sandstone walls. The location also serves as a breeding habitat for bat species, showing that despite restricted access for people, the site remains vital for local wildlife.
