The Island not far from the coast is the most recent and the largest volcano of Auckland. We took the ferry and went for a long walk to the summit of Rangitoto. Its amazing walking over large lava fields and climbing bigger lava stones. From the far you might think that there is only a forest on the island but the trees are more like 1.40 meters high and only the last bit of the path is forested.
The island is really unique and the view you have from the summit is fantastic!! We had a lot of fun the pathes were exceptionally empty for Auckland. I hope noone listened to us when we sang a few songs on the way to the top. They would have turned around for sure ^^
