The Treetop Walk Saarschleife is a 1,250 meter long canopy walkway in the Orscholz area of Mettlach, Germany.
Built atop a rocky vantage point known as the "Cloef", it offers visitors views of the Saarschleife.
The treetop walk was built by Erlebnis Akademie AG from Bad Kötzting thanks to a community initiative by Mettlach.
Many critics believed that the observation tower would mar the surrounding landscape and nature - particularly on account of the area's special meaning for Saarland and its wide visibility.
However, the Mettlach town council approved the project with a significant majority because of the tourism increase it promised to bring.
