Baumkronenweg Kopfing, Treetop adventure park in Kopfing im Innkreis, Austria

Baumkronenweg Kopfing is a treetop path through the Sauwald forest near Kopfing im Innkreis, more than 1,000 metres long and built 15 metres above the forest floor, with a 40-metre observation tower. The structure rests on over 25 kilometres of round timber, some 700 cubic metres of wood, held together by ten tonnes of screws and bolts. A 5,000 m² adventure playground with a giant swing, a low-rope course and a 50-metre tunnel slide stand beside it.

Baumkronenweg Kopfing opened in 2005, funded with roughly one million euros through the Leader Plus initiative, with support from the Austrian federal government, the province of Upper Austria and the European Union. The project was intended to boost tourism in the economically weak region around Kopfing. In 2011 the site hosted the first "Woodstock der Blasmusik" brass music festival.

The walkway sits near the point where Austria, Germany, and the Czech Republic meet, giving the spot a rare geographic position. On a clear day, visitors standing on the upper sections can look out over all three countries at once.

The walkway is accessible without stairs thanks to ramps, which makes it manageable for strollers and visitors with limited mobility, though sturdy shoes are still a good idea since the wooden surfaces can get slippery when wet. Weekday visits tend to be quieter than weekends, when families often come in larger numbers.

At certain points along the route, there are tree houses where visitors can actually spend the night, sleeping in the forest canopy rather than just passing through it. From these structures, it is said to be possible to see into both Germany and the Czech Republic on a clear day.
