"Grindelwald Zip-Line For those seeking the thrill of paragliding at a much lower altitude, the Grindelwald ZipRider (known locally as the First Fleiger) provides the desired adrenaline rush. At 847 yards long, the zip-line hurtles visitors down the mountainside and over ski runs at speeds of up to 55 miles per hour. The attraction gets incredibly busy during the summer so arrive early to avoid long lines—dash, and don't forget your camera. The views of Grindelwald village, surrounded by Alpine mountains and wandering cows, are unforgettable."
