Out on the weekend of May
May weekend is one of the first opportunities for short tourist trips. Picnic can spend not only a home barbecue, but also for mountain walks or visiting Polish monuments of nature, and above all walks of large parks and greenery around the beautiful lakes. This way you can not only eat well, but also to spend time in the fresh air and the opportunity to see the history of Polish tourism. Weather in early May is sometimes different, but certainly much more conducive to family walks in the mountains, than the weather prevailing during the cold weather. In contrast, people who visit the large parks, may in designated areas also organize family camping.
