During our 90-minute Tunnels and Gunners Tour, an experienced volunteer guide will lead you through two sets of demilitarised fortifications set within 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.
