One place: Iceland.
1) The air is clean. I mean, super-clean. I went there when I was a teenager and suffered from bad skin, and within two days my skin had cleaned up entirely. It was incredible. We went on a little boat around the smaller island of Grimsey, and the water was blue. Not that bright, vibrant Mediterranean blue of travel adverts, but a more natural blue. And there were fish everywhere. It were proper amazing.
2) The views. Iceland has some amazing natural geography. The best place was a long valley-like gorge which turned out to be the boundary between the North American and Eurasian plates, which meant we were stood on two at the same time. We also climbed up an extinct volcano called Stora Dimon, and considering how flat Iceland is you can see for miles at the peak. We also quickly visited a beach that was made of volcanic ash and rocks, and it was bizarre to see something so...black. Like, onyx black. It was beautiful in its own way.
3) Reykjavik is lovely. The architecture is really different from what you see elsewhere in the world, and it's all nice and - you guessed it - clean. There didn't seem to be any pollution anywhere.
4) EVERYONE IS TALL AND BLONDE. It sorta freaked me out a bit. O: And they all spoke perfect English. It made me feel kinda embarrassed and lazy that I didn't bother to learn any Icelandic before we went (it was a class trip).
5) Goat's milk & goat's cheese. Don't knock it 'till you've tried it; I thought it was lovely.
Okay, so the geysers smelt a little...but they're geysers, they're supposed to. XD
I always thought that Iceland was amazing anyway for winning the Cod Wars of the 70's...I mean, there was half a million of them and around 55 million Britons, and they won. Incredible little country. <3
