March 20, 2026, World War II Gun Pits

The World War II Gun Pits at North Head are concrete coastal defence emplacements built to help protect Sydney Harbour during the war. The four pits sit in exposed positions overlooking the ocean, reflecting their strategic role in monitoring and defence. Today, the remains are open to visitors and are a stark historical contrast to the surrounding coastal landscape.

Manly Dam is a heritage‑listed site built in 1892 as the area’s original water supply, it was later upgraded several times before shifting to a recreational destination. You can follow lakeside trails, swim in the reservoir, or enjoy a picnic in the surrounding reserve. The water and catchment now support a mix of outdoor activities, while the historic concrete gravity dam still stands as a striking feature in the landscape.

Manly Dam Reserve is an easy escape into bushland on Sydney’s Northern Beaches. You can walk the 7.3 km circuit for lake views, wildflowers, and eucalypt forest, or head straight to the water for a swim or paddle. This area forms part of the traditional lands of the Gayamaygal and Garigal peoples, with Aboriginal heritage sites adding depth and history to the landscape. Birdlife is active all day, and you might spot a swamp wallaby if you stay into the late afternoon.

Bilarong Reserve spans roughly 5.3 hectares of riparian bushland and forms part of a corridor connecting the Deep Creek and Middle Creek reserves. The area is rich in birdlife, with black swans that are often spotted feeding on seagrass in the shallows, while waders and woodland birds thrive in the wetlands and forest edges. The Narrabeen Lagoon Trail passes directly through the reserve, making it a natural stopping point for walkers and cyclists. The playgrounds and picnic areas are great for families, and nature enthusiasts can enjoy birdwatching and quiet moments by the water. As a designated Wildlife Protection Area, dogs must be on lead to protect the reserve's diverse ecosystems.
