Baumkronenpfad Hainich, Canopy walkway in Hainich National Park, Germany.

Baumkronenpfad Hainich is a steel walkway and 44-metre Baumturm tower in Hainich National Park. The cylindrical concrete tower has an orange cabin with large windows near the top, reached by open metal stairs spiralling around it. The walkway runs 10 to 24 metres above the ground and is divided into four sections entered through gates named after a bat, woodpecker, wildcat and butterfly.

The Baumkronenpfad Hainich opened on 26 August 2005 as Germany's second treetop path, with a 300-metre route rising from 10 to 24 metres. A second 238-metre loop, dedicated to the ancient forest, followed on 14 May 2009. The 44-metre steel Baumturm was assembled segment by segment from prefabricated elements hoisted over the canopy.

Educational panels along the route describe bats and woodpeckers that live in this forest. Visitors learn about the animals and plants that inhabit the canopy layer by observing them from the walkway itself.

The walkway is well-maintained with clear markings and information panels throughout. Wear comfortable shoes and allow time to stop at viewpoints along the route to fully experience the forest from different heights.

The 40-metre Baumturm carries a weather station on its roof, run by the University of Göttingen. The tower also serves canopy research: its permanent structure gives scientists easy access to small mammals, birds, beetles, spiders and butterflies, replacing the usual climbing techniques.
