Inner lake of Tihany
What is that white foam? No, not chemicals or detergent! Only some organic materials: a sticky remnant of the mosquitoes' remaining skins of larvae and pupa. The substance is harmless to health and decomposes within 24-48 hours.
Outer lake of Tihany
This area is rather swampy, full of reeds with a small water surface. It gives home for many birds.
