We went there last year, sadly not on a bike. The Haast pass on South Island was fantastic, even in a car.
Te Anau to Milford sound on a fine day would be hard to beat. NZ will be like a ghost town in these places for a bit with no tourists coming in. Might have to head down there myself and make the most of it.
The Milford Road would be fantastic at present, no feckin tourists coming around any of the hundreds of corners on the wrong side or stopped in the middle of the road around blind corners etc.
Ah sure, dat's wear all de Leprechaun's live Is that the place near Dunmanway? Looks very familiar, Glenview Gardens I think it's called?
