The village is on the eastern bank of the Eder River. To the east of the village is the "Quillerwald" (English: "Quiller Forest") or "Markwald" (English: "common forest"). This forest once belonged to all the villages around it. The people of the villages were allowed to cut down trees and to let animals feed there, but they were not allowed to hunt in the forest. The Eder River meets the Fulda River just 9 km (5.6 mi) upstream from Altenbrunslar at Edermünde.
