Hike for Sight, a 34km challenge to step up and support The Fred Hollows Foundation. Give the gift of sight and change the lives of some of the world’s most vulnerable people. As little as $25 can restore sight to a needlessly blind person. Help train and empower local eye doctors, nurses and health workers to create sustainable eye care in the communities that need it most. The Foundation’s work has a clear purpose – to ensure that everyone has access to high quality, affordable eye care.The Sydney Harbour Hike app shows the complete route for the hike, with markers throughout the map showing key waypoints, water stops and other useful information.
