The most ambitious walking normally attempted in Auckland is a stroll through The Domain or a more demanding hike up to one of the volcano-top viewpoints. The best of these have been threaded together as the well-marked Coast to Coast Walkway , a four-hour, 13-kilometre route straddling the isthmus from the Ferry Building on the Waitemata Harbour to Onehunga on the Manukau Harbour. By devoting a full day to the enterprise you can take in much of the best Auckland has to offer, including excellent harbour views from The Domain and the summits of Mount Eden and One Tree Hill, the Auckland Museum, Albert Park, and numerous sites pivotal to the development of the city. All is revealed in the free Coast to Coast Walkway leaflet, which includes an indication of where the walkway intersects with bus routes for walkers who want to tackle shorter sections.
