Federseesteg, Wooden boardwalk in Bad Buchau, Germany.

The Federseesteg is a wooden pathway built through moorland and reed beds surrounding Federsee lake in Bad Buchau. Along the route there are several observation areas, benches, a viewing tower, and information boards about the local plants and animals.

The first boardwalk was built in 1911 on the initiative of forester Staudacher, after Lina Hähnle, founder of NABU, bought 16 hectares of the Staudacher reed area. That original walkway was 700 metres long and built by hand. It was renewed in 1949, 1961–1965, 1983–1985 and 2010/11 for its centenary, each time in winter, when frost makes the soft moor ground passable for tracked vehicles.

The boardwalk crosses the protected Staudacher area, a 16-hectare reedbed that Lina Hähnle, founder of NABU, bought at the suggestion of forester Staudacher. The first 700-metre walkway was built by hand in 1911 on his initiative. Today the path draws up to 100,000 visitors a year, and local people from Bad Buchau and neighbouring villages use it for recreation.

The boardwalk is open all year, but most visitors come in spring and summer, when more animals are around the lake. It can only be entered from Bad Buchau, where a car park and a tourist information office stand at the start. Benches and a shelter are distributed along the route.

Workers can only repair or expand the boardwalk during winter when the moorland ground is frozen solid enough to support heavy equipment. This means major maintenance happens only under very specific weather conditions.
