People began to travel ages ago. The very first travellers were explorers who went on trips to find wealth, fame or something else.
Their journeys were very dangerous-but still people keep on going to the unknown lands.
Nowadays it is not as dangerous and much more convenient. Do you want to go somewhere? Hundreds of companies are there to help you. They will take care about your tickets and make all the reservations needed.
You don't speak the language of the country you go to? There are interpreters that will help you.
With modern services you can go around the world. You can choose the means of transport you like: plane, train, ship, bicycle or you can travel hiking.
Tourism became a very profitable business because people are ready to spend their money for the great opportunity to have a great time learning about new countries, going sightseeing, resting and enjoying themselves.
