I love this place because going there reminds me of my trip to Alcatel. There is a fascinating history of isolation and incarceration that not everyone knows. I especially enjoyed seeing Wellington and Hutt Valley from a new perspective...it was cool to stand at the highest point of the island and turn around to see all parts of the harbour. I would recommend bringing a picnic lunch. The ferry timetable can be a bit confusing but you can take a class in the morning and come back in the afternoon. Enough time to stroll around the island and enjoy some of the tracks and beautiful views around. If you really like it, you can even book one of the two houses on the island and spend the night. Check the Department of Conservation website to see how it works. Overnight is definitely something I want to do
