The Eselsweg (English: "donkey trail") is a long-distance hiking trail that follows an ancient trade route through the Mittelgebirge Spessart, in the states of Hesse and Bavaria, Germany. It is 111 km long and leads from Schlüchtern in the valley of the Kinzig river to Grossheubach on the river Main. The trail follows an ancient trade route on which donkey caravans used to transport salt, thus giving rise to the name.
