Great hike! We took the first ferry to the island that day (this is highly recommended as the sun is intense in the afternoon and it is hot especially in summer). Very recommended for this trip, once standing at the top you can see great views of Auckland and the port. Not very used to such heights for us Midwest people, many places are more moderately steep, but not too bad. We saw children taking part in such hikes with their families. A great way to spend half a day in Auckland!
