A pleasant path follows the Wiese River, in the Kleinbasel section of the city (east side of the Rhine). The terrain is a combination of gently wooded path, with some views to fields and the small river. The path is on the south side of the river — the German border is on the north side. Some sections of the path are narrow.
Start near the Tierpark Lange Erlen (free zoo/park). Head east along the path for 4 km, after which continue on the road for another 1 km to the Wiesengarten Musetti (Swiss restaurant). You’ll pass the Lange Erlen city park, and then the wiesenmatt Nature Reserve. Retrace your steps or see the option below to run on the German side of the river.
Alternative Option: at the 3 km mark, you can cross over to the German side of the river, using the Weiher Steg pedestrian bridge, and run back along the Wiesendamm-Promenade, and then the Akazienweg, crossing back over at Lange Erlen park or the Alter Bahnsteg (bridge).
