This path connects the Quarantine Station to Eagles Nest and runs parallel to Defence Road through the coastal bushland. In the 1940's this sandy track serviced a telephone line installed as part of the upgrading of Melbourne's defences during the Second World War. The cable ran form Queenscliff 6 kilometers across the bay to Observatory Pointy and then to both Fort Nepean and Portsea. The track also allowed access between Fort Nepean and Observatory Point jetty by the military when weather conditions were unsuitable for berthing at the Fort Nepean jetty. Car parking is available at the Quarantine Station or Gunners Cottage (cars are not permitted past this point).
