I've actually traveled around the world several times over and would have to say Charleston, SC. Out of all the countries I've seen and states I've been to, it is by far the most amazing place I've ever been. There's a reason millions of people visit every year and it has grown over 10% in the past decade and it's because it really is that awesome.
If we're talking outside of the U.S., probably Vietnam. I went a while ago and it was amazingly beautiful. I went back in 1998 before Americans were really going back (they only started allowing them back in 1994) but now there are tons of resorts and such so it's a lot more like a place you'd wanna retire at.
Quoting Gir!:" <blockquote><b>Quoting BlueTeamXTwo:</b>" New Zealand. It's boss."</blockquote> ... [snip!] ... From what I understand, the people take care of the land there. It's gorgeous. Someday I'd like to see it, maybe hike you know?"
I love the tramping around here! My mum used to take my sister and I up mountains and on week long tramps through NZ it was amazing. Gorgeous scenery.
Honestly, I wouldn't mind retiring in Michigan, in my own house where my family is. We plan on building a passive solar house in two to three years and also growing a lot of our own fruit and veggis. For retirement that would mean inexpensive groceries as well as much lower house bills.
