Thanks to a great recommendation, we jumped on the ferry to Rangitoto at lunchtime on Sunday. 10 mins to Devonport and then 10mins across to Rangitoto.
Not being the fittest person, I was a bit apprehensive, as it does lokk a long treck up to the summit. I had top stop quite often to get my breath back, but after a few very steep stages, we finally got to the top! Amazing views and a sense of achievement for me!
We both said we would take a full day next time and bring a small picnic with us. You can also take several routes back down, so some options to fill out the day!
