Back in 1993, Mosman Council initiated the concept of a Harbour to Hawkesbury bushwalk, which would connect to the Great North Walk. Supported by Ku-ring-gai Council and the NPWS, a bushwalking route was established from Manly to Berowra Waters. The Harbour to Hawkesbury route traverses the Sydney Harbour National Park, Garigal NP, Ku-ring-gai Chase NP and Berowra Valley Regional Park, using existing bushwalking tracks. The Harbour to Hawkesbury walk is about 59km in length, but unlike the Great North Walk has no camping sites or accommodation along its length (public transport allows it to be done in smaller sections). You’ve probably seen the distinctive red logo (an H-H symbol with a bushwalker) on many track markers, despite all official references and information on the track having faded into obscurity.
The majority of the track is single trail with some rocky technical sections as well as some brief road and fire trail sections peppered throughout. Considering the proximity and accessibility from Sydney and the popularity of the Great North Walk it is astounding that the trail doesn't get as much attention nor end to end attempts. There are historic indigenous site located along or nearby the trail as it traverses Sydney's sandstone bushland, a truly special place.
