Modern life is impossible without travelling. Thousands of people travel every day either on business or for pleasure. They can travel by air, by rail, by sea or by road.
Of course, travelling by air is the fastest and the most convenient way, but it is the most expensive too. Travelling by train is slower than by plane, but it has its advantages. You can see much more interesting places of the country you are travelling through. Modern trains have very comfortable seats. There are also sleeping cars and dining cars which make even the longest journey enjoyable. Speed, comfort and safety are the main advantages of trains and planes. That is why many people prefer them to all other means.
Travelling by sea is popular mostly for pleasure trips. On board large ships and small river boats people can visit foreign countries and different places of interest within their own country. It is very pleasant to see the rise and fall of the waves, to feel the fresh sea wind blowing and hear the cry of the seagulls. Trips on the Volga, the Dnieper, the Yenisei, the Black Sea are very popular today.
Many people like to travel by car. It is interesting too, because you can stop when and where you like, you do not have to buy tickets or carry your suitcases.
A very popular method of travelling is hiking. It is travelling on foot. Walking tours are very interesting. Hitch-hiking is a very popular method of travelling among young people. But it is not so popular in our country as abroad.
The Black Sea is one of the most wonderful places which attracts holiday-makers all over the world. There are many rest-homes, sanatoriums and tourist camps there. But it is also possible to rent a room or a furnished house for a couple of weeks there. Sometimes we place ourselves in a tent on the sea shore enjoying fresh air and the sun all day long. As a rule I make new friends there. In the daytime we play volleyball, tennis, swim in the warm water of the sea and sunbathe. In the evening I like to sit on the beach watching the sea and enjoying the sunset.
