The 1999 storm, Hurricane Lothar, caused damage to approximately 30 million cubic meters of timber across Germany.
The forest at Lotharpfad was left entirely unmanaged after the storm to allow researchers to study natural reforestation processes.
The trail features a series of staircases that gain roughly 60 meters in altitude over the course of the walk.
The ground in the affected area consists largely of Bunter Sandstone, which influences the types of plants that colonize the site.
The site demonstrates 'deadwood' ecology, where decaying trees provide critical nutrients and habitats for fungi, insects, and small mammals.
The Lotharpfad is a 900-meter-long educational trail located within the Black Forest National Park that illustrates the ecological aftermath of a severe storm. In 1999, Hurricane Lothar flattened a 10-hectare area of forest, which was left to naturally regenerate without human intervention. Visitors traverse the area via a wooden boardwalk and staircases that wind through the fallen timber and emerging saplings. A central viewing platform offers an elevated perspective over the chaotic landscape and the surrounding Black Forest valleys. The trail serves as a living laboratory for observing secondary succession, where pioneer species reclaim the disturbed soil. Interpretive signs placed along the route explain the storm's impact and the resilience of the forest ecosystem. The path is situated at an elevation of approximately 1,000 meters above sea level. It is maintained by the National Park administration to ensure safe passage through otherwise impassable terrain.

Wear sturdy, closed-toe hiking shoes as the wooden boardwalk can be slippery when wet and there are uneven sections.
Bring a windbreaker or additional layers, as the high-altitude, exposed clearing is significantly windier than the surrounding dense forest.
Use the provided binoculars or a camera zoom to spot birds of prey that frequent the open landscape.
Do not attempt to climb off the boardwalk into the dense, tangled piles of fallen timber, as this is hazardous and ecologically damaging.
The trail is generally accessible year-round, though the boardwalk may be closed during severe winter conditions or if heavy snow makes maintenance impossible.
Stay strictly on the designated boardwalk to protect the sensitive regenerating vegetation; do not remove any wood or plant material.
