My summer holidays.
Summertime is my favourite season because it means freedom from my school and hard studies. I usually go to bed after midnight in summer and I can sleep as late as I can. It’s a big deal for me because I get really tired of waking up early during the school year.

The most important thing for me is to spend exciting and fantastic summer holidays loaded with activity and adventure. During our long summer holidays I have much fun meeting my friends, going to a summer camp, swimming in the river and eating plenty of fruits, berries and ice-cream. Sometimes my family travels somewhere to a warm and beautiful place near the sea. We spend much time swimming, diving, sunbathing and building sandcastles and sculptures, we also go sightseeing and try the national cuisine in new places. And we take a lot of funny pictures there.

In July or August I often go to hiking expeditions along the river with my elder brother and our friends. As a rule our hiking trips last for about 4 or 5 days. It depends on the weather. Hiking is really arduous and thrilling. You have no mobile phones or the Internet there. You just relax, enjoy the nature and fresh air of the countryside, sunbathe at the beach, play volleyball, go fishing and boating, live in a tent and cook on the fire. Hiking is worth going because you also learn to live and help each other in a team.

My summer holidays are always full of unforgettable impressions. I long for the next holidays because I am sure I’ll have a great time again.
