The popular tourist destination of the Lauterbrunnen Valley, in the Swiss Alps, is fast becoming well known for something other than its beauty.
Base jumpers, who are attracted to the high vertical cliffs, launch themselves off - jumping 700m to the valley floor.
"Some people play tennis or golf, I like to go jumping," explains base jumper Justine Edde.
BBC News joined Justine and her friends as they prepared for another leap.
