The Great North Walk - Lane Cove River Valley

Spanning the distance between Hunters Hill and Thornleigh, the Lane Cove River section of the Great North Walk offers a remarkably diverse journey through the northern suburbs of Sydney. Tracing the winding valley from tidal mangrove flats and historic pleasure grounds up to shaded sandstone gullies and secluded creek crossings, this route packs an impressive wealth of natural beauty and colonial history into a surprisingly accessible, albeit long, day hike.

The Great North Walk

In a search for a long hike around Sydney, my mind turned back to the Great North Walk—a massive 250-kilometre trail linking Sydney to Newcastle—and my unhurried attempt to complete the entire route in stages. Having already explored the sprawling wilderness of Ku-ring-gai Chase and Berowra Valley National Parks, I decided to tackle a section tucked much closer to the heart of the city: the lush gully forests and tidal river reaches of Lane Cove National Park.

Tucked into Sydney's northern suburbs, Lane Cove National Park feels a world away from the urban sprawl enclosing it. Following the winding course of the Lane Cove River, this protected valley preserves a surprisingly tranquil corridor of Sydney Sandstone Gully Forest, where towering smooth-barked apples, mangroves, and quiet waterways replace city noise. Its network of walking tracks—many built by Depression-era relief workers—winds past historic stone picnic shelters, ancient First Nations rock sites, and riverbanks alive with water dragons and birdlife, making it one of Sydney's most accessible wilderness escapes.

Boronia Park

I began my hike at Boronia Park, tucked into the historic sandstone suburb of Hunters Hill. In the context of the Great North Walk, this reserve marks the trail's first true transition into native bushland after leaving behind the glass and concrete corridors of the Sydney CBD. Joining the track at the southern end of Princes Street, the forest opens up to deliver your first views of the Lane Cove River as it flows beneath Fig Tree Bridge—the point where the quiet river estuary meets the broader waters of the Parramatta River.

The park offers a rare window into pre-colonial New South Wales, preserving an intact, highly diverse expanse of bushland that showcases Sydney's landscape as it existed prior to European settlement. The track skirts the water's edge, traversing rocky sandstone slopes shaded by open eucalyptus canopy and towering smooth-barked Apples before dropping down into swamp she-oaks along the shoreline. At one point, a low finger of dry land pushes out into the estuary, allowing you to step right into the heart of the Grey Mangroves—a quiet, muddy realm where pneumatophore snorkel roots rise from the silt and fiddler crabs scatter with the tide.

Buffalo Creek

The track leads into the picnic grounds of Buffalo Creek Reserve, where a wooden footbridge spans the tidal mudflats before carrying the trail into the national park at Sugarloaf Point. The area owes its name to HMS Buffalo—a historic Royal Navy store ship that brought early free settlers and crucial supplies to the fledgling Sydney colony in 1799. Local records indicate two of the district's earliest European landholders arrived in Port Jackson aboard the vessel. Today, crossing the creek marks a distinct transition on the Great North Walk, leaving the picnic grounds behind as the trail steps beneath a canopy of mangroves and saltmarsh into the park proper.

The Fairyland Track

Beyond Sugarloaf Point, the trail skirts another broad expanse of mangroves and the playing fields of Magdala Park before making two river crossings in quick succession—first over a pedestrian bridge, and then directly across busy Epping Road. Leaving the urban traffic behind, the Great North Walk joins the Fairyland Track to continue into Lane Cove National Park proper. This quiet section passes through the site of the historic 1920s "Fairyland Pleasure Grounds".

The section through Fairyland is a highlight of the trail, tracing the tranquil riverbank to the site of the historic Fairyland Pleasure Grounds, originally known as "The Rest". Established in 1920 by the Swan family, this peaceful clearing once echoed with music and laughter as families arrived by river launch to dance, swing, and picnic by the water. While nature has reclaimed most of the grounds, careful observers can still spot mossy concrete steps, old footings, and stone foundations hidden in the ferny undergrowth, with excellent interpretive signs revealing what the bustling park looked like a century ago.

Lane Cove River Weir

A brief road connection links the Fairyland Track to the main visitor precinct at Riverside Drive, where the trail reaches the historic Lane Cove River Weir. Constructed in 1938 as a Great Depression relief project, the weir was built to create a tranquil freshwater lake for picnicking and rowing—a tradition that continues today at the nearby historic Lane Cove Boatshed. While the dam transformed local recreation, it abruptly blocked the river's flow, leading to silting issues and disrupting native aquatic life. To remedy this, a vertical-slot fish ladder was installed, allowing migratory native species to bypass the barrier. When water levels are normal, walking directly across the concrete causeway over the weir offers a seamless—and scenic—river crossing.

The precinct is a popular hub for weekend visitors, packed with grassy picnic flats, a café, and drinking water refills—making it the perfect mid-hike pitstop to top up water bottles or grab a sugary snack. From here, parallel tracks trace the river north toward De Burghs Bridge, five kilometres upstream: the Riverside Walking Track along the western bank and the Great North Walk along the eastern bank. For purists tackling the official Great North Walk, the true route sticks strictly to the eastern shore.

The track climbs away from the road initially, merging into a wider management trail before dropping back to the riverbank, heading toward Blue Hole and Fiddens Wharf. It's a beautiful section of the Lane Cove River.

Beyond Fiddens Wharf, the walk grows increasingly rugged and varied, dipping through moist, fern-filled gullies, negotiating small stepping-stone creek crossings, and hugging narrow, unfenced ledges high above the water. Following the river's upper reaches, the path weaves beneath a series of towering sandstone overhangs—carved out by millions of years of weathering—before emerging within sight of De Burghs Bridge. Soaring high above the tree canopy, this major arterial road carries the A3 Ryde Road across the valley, marking a dramatic transition back to civilisation.

Passing right underneath the concrete arches of De Burghs Bridge, the Great North Walk leaves the river behind for a steady uphill climb. The humid creekside greenery quickly transitions into a drier open eucalypt woodland, characterised by smooth-barked apple trees and stubborn stands of grasstrees.

Upper Lane Cove River

The next few kilometres take on a quieter character compared to the lower reaches of the river. Descending from Rudder Creek along a rocky path, occasional clearings offer sweeping views across the valley before the route crosses Quarry Creek and briefly joins the Gloucester Avenue fire trail. Dipping back onto the Valley Walk, the trail crosses Congham Creek via small timber bridges, briefly skirting suburban boundaries while keeping a firm foothold in the native bushland.

Descending toward Avondale Creek, the path opens onto a sandy river beach and shallow ford that feel surprisingly remote. Crossing the creek, the track continues along the valley floor before joining the paved shared path down to Browns Waterhole—a famous local landmark named after 19th-century timber merchant John Brown, whose bullock teams once camped here. Today, the broad concrete causeway crossing the wide, tranquil river pool serves as a popular link connecting South Turramurra to Macquarie Park.

Upstream from Browns Waterhole, the trail follows the Step Track, named after the local conservation group that helped save this upper valley from development in the 1970s. Passing the distinctive overhang of Whale Rock, the path crosses the river several times via rocky stepping-stone fords before reaching Conscript Pass. Here, Depression-era relief workers in 1932 hand-chiselled a staircase straight through the sandstone cliff face, leaving behind rock carvings of "CONSCRIPT PASS" and a caricature of NSW Premier Bertram Stevens.

Climbing through Conscript Pass and continuing up through Lorna Pass, the track leaves the river behind and reaches the boundary of the historic Baden-Powell Scout Centre—a popular overnight camp spot for end-to-end Great North Walkers. From here, the bush gives way to Thornleigh Oval and suburban streets. Crossing Pennant Hills Road via the footbridge, I reached Thornleigh Station—closing out an incredible 20+ km hike through the heart of the Lane Cove Valley.

Stepping onto the platform at Thornleigh, it felt good to tick another solid chunk off the Great North Walk logbook. From the mangrove mudflats near Hunters Hill to the historic hand-carved stone steps of Conscript Pass, this section offers a surprisingly rich slice of history and bushland right under the nose of suburban Sydney.
