Kate Middleton, 39, who is Honorary Air Commandant of the Royal Air Force Air Cadets, took the plunge this afternoon at Cathedral Quarry in Little Langdale, Cumbria, with a group of Air Cadets.
The mother-of-three was practical as she arrived at the RAF Air Cadets' Windermere Adventure Training Centre, rewearing her khaki coloured Seeland puffer jacket and a pair of black jeans.
The royal finished the look with her £250 trusty brown suede See By Chloé boots, which feature leather trim detailing on a round-toe, lace-up base.
Thirteen-year-old Itelouwa Odipe, from Lancaster, spoke to the duchess as she waited to try abseiling, revealing: 'She was about to abseil and I was next in line so she asked me if I wanted to go before her. I was a bit scared so I said no. She said if I did she would meet me down there.'
Later, Kate met with surviving 'Windermere children' who were rescued from concentration camps and taken to the Lake District during a visit to Cumbria.Read more from The Daily Mail.
