Queenstown is known for all kinds of extreme sports and more or less crazy activities. The first bungee jump in New Zealand took place from a bridge over the Kawarau River near Queenstown. To this day, you can test your courage there. We looked at the bridge and the view, but we didn't dare to jump.
To have an even better view, we took the cable car to a lookout terrace from which you could overlook parts of Queenstown and Lake Wakatipu.
At the top, there was the "Luge" for those who prefer to go a little faster. There you could ride downhill in small carts.
Of course, we also took a walk through the town, for which you don't need too much time. Queenstown seems to consist mainly of hotels, restaurants, and booking agencies for activities.
