The road between Nelson and Christchurch is the one that I find the most comfortable to drive on.
It is very enjoyable to drive and the scenery along the way is also very beautiful.
If there is a chance, I still recommend trying to drive on this road.
Especially one of the roads from Nelson Lake to Murchison.
It has a very strong jungle feel. It's a pity that it's impossible to take pictures during the up-and-down waves and thrilling moments.
