What are great international locations to work at?

I'm ~4.5 years into my career and I'm thinking about doing something outside of the US for my next job. I'm looking to jump in about half a year, so right now is the time to figure this stuff out.

I've got no responsibilities, no kids or SO at the moment, so now would be the perfect time in my career to do something wild. Where do people recommend for culture, outdoors, tech, and /or ease of visas?

For example I was thinking about New Zealand.
