Mazurian Lakes - temporary collection of links
A brief search for Mazury comes up with a large number of sites, most of them in Polish, which is a bit limiting.
A lot of these sites are adverts and do not include images or general tourist information. Below I include a few links, which although in Polish include some photos of this beautiful part of the World.
http://www.jezioro.com.pl - excellent site, pity that there is no English version
Lake Wiartel (1) - photo of a small lake, one of my favourites
Lake Wiartel (information in Polish)
Pisz a small town at the Southern end of the Lakes
Wegorzewo another small town, this time at the Northern end of the Lakes
Mamry - one of the biggest lakes - clean and beautiful.
