Don’t look down! A new pedestrian bridge suspended 175-feet above the rocky gorge cradling the Paiva River opened in Portugal this week, and it’s now the longest of its kind. At 1,700 feet, Arouca 516 eclipses the former record-holder, the 1,621-foot Charles Kuonen Suspension Bridge in the Swiss Alps, as it stretches across the UNESCO-recognized Arouca Geopark. The steel construction is located in a five-mile stretch of the gorge known for its wooden walkways, adding another option for intrepid explorers to experience the lush scenery.
