Wigry National park has a lot to offer: wild animals (including beavers that transform the landscape by creating dams), traces of 12,000-year old Palaeolithic houses, and the underwater world of Lake Wigry from onboard a glass-bottom boat.
If you are lucky enough you’ll get to meet Maciej, who heads the local Museum. He and his family are committed to protecting the local ecosystems. Through the rounded “windows” of Maciej’s small boat you’ll discover a unique kind of sponge that lives in the shallow parts of the lake – apparently this weird, cute sponge is the living proof that the Lake’s waters are pure.
Try to spot the cormorants – yes, these huge, fish-eating, black birds over there. Weird but true: their faeces (poo!) is slowly causing the whitening, and will ultimately cause the death, of the trees in which these birds build their nests!
