Featuring gun emplacements, underground tunnels and other military relics dating back to the 1870s, Georges Heights at Headland Park, Mosman once played a crucial role in the defence of Sydney Harbour...

During our 90-minute Tunnels and Gunners Tour, an experienced volunteer guide will lead you through a set of demilitarised fortifications surrounded by coastal bushland, including tunnels off limits to the general public. The tour concludes at the Headland Park Artist Precinct, which is home to a thriving community of painters, potters, sculptors and photographers.


Tickets are $10 per adult, $7 per child (16 and under) and $7 per concession holder (incl. pensioners and students). In addition, family passes are available for $20 and include tickets for two adults and up to two children or concession holders. Note: Online bookings are essential. 

Subject to guide availability, we also accept private bookings for groups of at least 15 people. To request a private group tour, complete our enquiry form.
