It wasn't cheap, the two almost aerial photographs taken from the Visegrad castle costed 1700 HUF (~5 €). But totally worth it to climb up there to take a look on the upper tip of the Szentendrei Island and the new islands of Kismaros and Nagymaros.
I would like to start with the least obtrusive thing: there is a recent archaeologic excavation on the Sibrik hill, Visegrád. If somebody is not familiar with this place there was a late Roman fortress on this hill and later it became the center of the Pilis county in Hungary.
But let's go further:
Date, water level: 10.04.2015 Nagymaros 15 h -27cm
From the left there is the treeless river bank of Nagymaros, a long island and further right the Marosi Island. In the foreground there is the Szentendrei island and the vast gravel bank on its northern tip. And those small white dots aren't motorboats...
...but gravel banks, eight in number. There are curious people on them. If a curious person has the height of 17,7-1,8 meters the furthermost gravel bank extends 60 meters into the Danube counting from the end of the Szentendrei Island.
This end of the Szentendrei island is continuosly groving against the stream. More and more gravel bank emerges from the river. Without any human impact these gravel banks will join the body of the island.
