Mine have been Spain, France, Italy, Japan and recently South Korea. South Korea was by far the best especially going to the places you see in the drama series. Even my kids loved it.

Have been to Spain, US, Russia, Armenia, Ukraine, Azerbaijan, Uzbekistan, Kazakhstan and South Korea. I really enjoyed my trips to the US, especially when I visited relatives in California, but my favourite I would say is South Korea. 
I'm from Latvia and have been to:
Lithuania (like 3 or 4 times 'cuz it's right next door, possibly more, mainly Klaipeda, Palanga & Vilnius)
Sweden (only Stockholm thou, but 3 times 'cuz it's just a ship away)
Poland (Gdansk and some other places)
France (Strasbourg)
UK (London)
Czech Republic (Prague and a bit of country)
Hungary (mainly Budapest)
Croatia (I think I've been all over that one, but mainly by the coast)
Malta (mainly Valletta)
Madeira (went all around it, so, nearly everything)
Spain (Madrid & Salamanca)
Portugal (lived there for 5 months while on Erasmus soooo - saw quite a lot, but mainly lived in Barcelos then Porto & a bit in Lisbon)

I think that's it, haven't been anywhere else, 'cuz countries, like Germany or Slovakia, Austria, Slovenia etc while I have been there, it was only while traveling through, so they don't count.

My favorite is probably London (because I got to see all those places we see in movies in real life) & Croatia, Malta, Madeira 'cuz they have the kind of nature we don't have here - warm (hot) weather, real mountains & azure water ^^
Most of Europe, Canada and USA. The favorite Venice Italy.

I'm from the US. I've been to Canada several times (although I live pretty close to the border), and once to Israel. I've been on the border between the US and Mexico before, too. The signs near there said you were about 10 steps away from entering Mexico, so I've come close. It'd be cool just to visit there. Israel was quite a trip. I liked half of it. Ended up meeting with my group a day or 2 late, and it was supposed to be for 10 days. Certain areas of Israel were amazing. Visiting the Bedouins, going to Tzfat, an olive press, and kibbutz was great. The top of Masada was cool, although the trip up to it wasn't so great. I think, overall, I've liked the places I've been to in Canada more. But, I'm more familiar with it.
I live in the US....

I've traveled to:
Mexico (all over, but I really loved Oaxaca & Puebla)
