my summer holidays . Expressing opinion

    Some people claim , that hiking tours are interesting and useful for health while other argue that they are difficult , tiring and can be dangerouse . I think , that hiking is great idea how you can spend your holidays. It is realy very interesting , useful and not so expensive. Now I would like to express my point of view on tre problem of hiking tours.
    Some people argue , that hiking is great . To begin with , Hiking is great way to improve or chek your health. Hiking it is long pedestrian trekking. Muscles of your legs is working better , that in gum or simpe walking. Especially if you have heavy backpack. The same way , your back are working. For exampe , I had some hiking , and my legs became stronger . Now I can ride on bicycle more faster and for londer distation , than two years ago. Another plus of hiking , it is clean air and water . Your lungs will became cleaner . Toxins will go out of your body . Especially if you treking for long time (5 or more days) or in mountains . For exampe , I was have some cough  , but after hiking tour it less . One more plus , is that you can see lots of hidden places , true nature and silence.
    In the other hand , there is some minuses of hiking . Firstly , sometimes it can be dangerouse. Because of wild animals , weather (especially for mountains) , not enough knowlege of terrain. If weather will change so fast , you can get hypotermia , after that ill or even die . For example , in one of my hiking tours , storm started and I became ill.
     So in most part , sucessful of hiking depends of you and your group . You just need to have some knowledge and be carefull. Hiking is not expensive and great way to spend your holidays .
