The Schwanheim dune was created about 10,000 years ago as a result of the last ice age. The wind blew fine sands out of the riverbed of the Main. The vegetation is extremely rare and ecologically valuable. Its representatives of rare plants include Corynephorus canescens, Teesdalia nudicaulis and Armeria elongata. In addition, some pines (Pinus sylvestris) grow on the poor sand, which are reminiscent of distant sea coasts with their bizarre growth. The dune has recently been used to mine sand and gravel, as can be seen from the ponds. But of course this is also a nice area for birding.
Bus route 51 to the Schwanheimer Friedhof stop. Tram lines 10, 11 to the Bolongoro Palast stop and then take the ferry to Schwanheim. The nature reserve is crossed by 2 cross paths (north - south / east - west). The sandy areas are laid out with wooden planks over a length of 400m so that the sensitive living space is not entered by people and is thus preserved.
