The roads here are uncomplicated. There aren’t many choices. Retrace to Queenstown, turn right and over another pass, down to Twizel. That’s 240km ish.
Not before stopping at the spectacle of a fine 1880 suspension bridge, renovated by a percentage of the funds raised by the people who pay to jump off it. An easy 200NZD parted with.

Built originally to house dam workers for some massive, as in massive, hydro electric schemes, it is now booming. Well property prices anyway. No wifi in our overspill available, though it is a rather superior shed.
