Travelling by sea is very popular. Large ships and small river boats can visit foreign countries and different places of interest within their own country.

As for me, I prefer travelling by car. I think it's very convenient. You needn't reserve tour tickets. You needn't carry heavy suitcases. You can stop wherever you wish, and spend at any place as much time as you like.

Every year my friend and I go somewhere to the South for holidays. 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 can 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 day-time we play volley-ball, 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. I'm fond of mountaineering. So I do a lot of climbing together with my friends. Time passes quickly and soon we have to make our way back. We return home sunburnt and full of impressions.
