Kaiserhain not only is the northern Entrance to the Westfalen Park komoot.de/highlight/198975 , it also has a lovely lily pond with Canada geese and benches shaded by rows of trees. The linear Stadtwäldchen park leads as a car-free green trail straight here from Downtown via Stadtgarten. To continue toward the Emscher Trail or Phoenix See without cutting through the (1.50 Euro) Westfalenpark, one can use the trail leading around the western edge of the Westfalenpark and down to the Buschmühlen entrance, where a bridge leads across the stream to join with the Emscher Trail.
