A section of the 288km Lahnwanderweg following the Lahn river upstream from Marburg's Elisabethkirche through the Lahnknie nature reserve toward the village of Caldern, with a detour possible to the Weißenstein ruins.
This section of the 288-kilometer Lahnwanderweg follows the Lahn river upstream from Marburg's Elisabethkirche through the Lahnknie nature reserve toward the village of Caldern, in central Hesse. The trailhead is the Elisabethkirche in central Marburg, within walking distance of Marburg's main train station, so no car is needed to reach the start. The 12-kilometer route gains about 120 meters, following flat to gently rolling riverside paths on gravel and packed dirt, with no technical difficulty and no exposure. Shade comes from riverside trees and the wooded slopes of the Lahnknie nature reserve, a meander of the Lahn protected for its floodplain habitat, while more open meadow stretches offer views across the valley. A signposted detour partway along leads up to the ruins of Weißenstein castle, a modest but worthwhile climb for those wanting a break from the flat valley floor; this detour point also serves as a natural turn-around for a shorter walk back to Marburg. The trail continues along the river into Caldern, a small village with a regional bus stop for the return to Marburg. Water sources along the river are not reliably potable, but Caldern has a shop and the trail passes through Marburg's urban area at the start, so hikers can carry limited water and top up at either end.
