The Coast to Coast Trail runs between Waitemata Harbor and Manukau Harbor in the city of Auckland, New Zealand. It is 10 miles long and does have some modest climbing , mostly up and then down Mt. Eden, the local high point. This is an urban walk but don't let that fool you. We saw a lot and were very pleased with this hike through neighborhoods and parks. Enjoy the audio diary.
You can learn more about the trail in many places. Here is just one that includes a map.
