In 1996 I walked immediately past it and could watch the chicks in the nest. On this visit that path was choked with nettle and the birds were already fledged in any case. Many juveniles were resting on the sandy margins of the impoundments. This caused a couple of adult guardians to see fit to call everyone's attention to the grave danger I presented as I scanned the pool, by noisily and unremittingly dive bombing me over a ten-minute period. This is a good spot to spend an afternoon with your lover or your family, wandering through fields or forest on a rather large island cut out by an oxbow of the Rhine.
Cars are more or less excluded.
There is a concession stand just over the bridge there, and at least one restaurant on the island. I believe one can rent boats at Erfelden. It is said that a number of interesting birds occur, and Crane stop by on passage, but I did not stay long enough to find them. I was tired and it was threatening to rain, so I went on. The large ponds on the map turn out to be heavily used for fishing and swimming, but there seem to be further areas I did not get to which may be good.
