The First Flyer, a new zip line in the Jungfrau region of Switzerland, allows four people to simultaneously, yet independently, zip across Swiss alpine meadows at over 50 miles per hour and nearly 150 feet up in the air. Even better, this little contraption offers an adventurous reward for our hikers coming off the Schynige Platte, (Day 1 of the Jungfrau Loop), above Grindelwald. The ride takes about 45 seconds and covers a distance of around one-half mile between the lift stations of First and Schreckfeld. Riders disembark at Shreckfeld and may continue their descent to Grindelwald by foot or public transport.
I would certainly stand in line for this.
