New Zealand seems popular. I'm going to have to go for that too. It really is the most fantastic place I've ever been to. I'd absolutely love to live there.
My favourite place in NZ is a pebble beach at Kaikoura. One day, when I was feeling stressed and tired, I stumbled across this fantastic pebble beach with nobody on it. I sat down, watched and listened to the waves of the aqua-green Pacific Ocean, the perfect blue sky, the seagulls, and the cliffs of New Zealand stretching off into the distance and I felt so relaxed, possibly the most chilled I've ever been.
The funny thing is that this beach wasn't mentioned in any of the guidebooks and unfortunately I don't even have any photos of it.
