Hidden between rock-strewn Unesco mountains, the bridge, called 516 Arouca, hangs 175 metres (575ft) above the fast-flowing River Paiva.
The attraction cost about 2.3million euros ($2.8 million/£2million) and took around two years to build.
The average person will take five to 10 minutes to complete the walk across the bridge, depending on nerves.
