Great North Walk: West Pymble to Hunter's Hill is a 11 mile point-to-point trail located near the city of Marsfield that features a river and is good for all skill levels. The trail is primarily used for hiking, walking, and trail running and is accessible year-round.
South from West Pymble (near Mars Creek confluence with Lane Cove River) to De Burgh's Bridge; then alongside the river, past Fiddens Wharf and Lane Cove Park through the Fairyland Park near Delhi Road/M2 (at Mowbray); onwards down-river past Field of Mars and Buffalo Reserves and Boronia Park; under Victoria Road to the park fronting the river estuary and ending at Mount Street, Hunter's Hill. This is a family-friendly walk mostly in the Lane Cove River National Park. The meandering path here does indeed wander to and fro, never far from the banks of Lane Cove River, sometimes leading us high above it and then dropping down to the waterside, enveloping us in a moist coolness. There are plenty of toilets and water taps and in the southern part (around East Ryde).
