For me, boat trips are ideal: I don't have to walk, and the birds are often easier to see than on shore. The main attractions are the colonies of Pink Pelicans and Dalmatian Pelicans. When the valley was still a large swamp, the pelicans could survive here, but now they have to be helped with breeding islands in the lake. They are also fed additionally. For me the most beautiful photo was that of the Red-necked Grebe, a beautiful little grebe in breeding.
