One of my colleagues had told me that when I was in Karamea I had to look at these limestone arches. They’re 15km down an unsealed road and then there is a 15 min walk. However it’s well worth the detour if you’re in the area.
It’s actually very difficult to fit the arch in to a photo – the one I went to was about 40mx30m.
You can’t go right in but the arch is 200m long
There are other things to look at in the same area so you could easily spend half a day or more here.
