Traveling (That is the American spelling. In English it is: Travelling)

I want to visit countries, where people speak English, what do you advise? And What beautiful places are there:)

It depends on budget and your holiday preferences.

For the chance of a palm tree on a tiny island all to yourself, with total quiet I recommend the Maldives.

For six star hotels and 40C temperatures, go to Dubai.

For a taste of the Caribbean, I recommend a cruise, you could see a different country almost every day. (Just avoid starting in USA - it's too much hassle.)

The Gambia lets you feel rich, but you might not have running water or electricity all day. However I did handle a small python and touch a live crocodile!

If you don't mind very cold temperatures, (-30C) in Lapland you might see the "Northern Lights".

If you want to ride an elephant, you could try Sri Lanka.

For something a bit different, try Mauritius or Cape Verde.

I still hope to see Australia & New Zealand.
