When the water level of the Rhine is low, you can walk to these islands on dry feet.

From October 2014, the tomato islands were redesigned for around two million euros. The construction work was part of a nature conservation project that was partly financed with funds from the EU funding program LIFE+. A ditch was created at Auer Köpfle through which Rhine water is channeled into the Illinger Altrhein. In addition, two channels were created along the right bank of the Rhine, for which the existing groynes were divided. The excavated material was used to raise the islands. The construction work created three islands that provide gravel breeding areas that are safe from predators such as foxes. https://de.wikipedia.org/wiki/Tomateninseln

Just 200 years ago there were numerous islands on the Rhine that kept changing when the water was high. With the regulation of the Rhine, however, these were largely lost and with them breeding areas for various waterfowl. As part of the LIFE+ project "Rheinauen bei Rastatt", three islands were created at the mouth of the Illinger Altrhein, on which waterfowl can stay, search for food and breed undisturbed. http://www2.lubw.baden-wuerttemberg.de/public/abt2/dokRepository/upload/10_12/919001000152/nreservat_auer_k_pfle_-_illinger_altrhein_-_motherner_w_rth_-_umgestaltung_kohlkopf_und_tomateninsel__infotafel_.pdf

the southern Murg side (corresponds to this highlight) is the beautiful side of the Murg estuary. You can only get here on foot or by bike. There is also a road on the other side of the Murg.

An impressive tree that would certainly have a story to tell. Distinctive waypoint and good for route description with the locals. Actually, everyone here knows the old oak tree like the sandy beach, sailing and paddling club, border point island and Illinger island, etc. etc...
