"For a 7-year-old to get up there is a great achievement."
Frank Schreiber said his daughter is very outdoorsy and loves mountains but her lack of fear surprised even him.
"I said 'Are you scared?' She said, 'No, it's all right'.
"We got up to the top and there's another 3m to the actual tippy top, and she was not on the rope and was like 'Oh well that's where the pole is' and ran up. She was like 'Wow, that's cool, where's Queenstown?"'
Sarah said the only thing she was nervous about during the climb and descent was not getting to the top - and matching the feat of 9-year-old brother Ben who did it last year with Frank.
"I was a bit nervous when going up because I really wanted to get up to the top 'cos it was my first time going up there and because it was the highest peak of The Remarkables," she says.
"I'm really happy. It was a big achievement."
Prudden adds: "The best thing about it is it's a young person not totally distracted away from the natural world and into computers and computer games.
"In the long term they'll take that with them, both as a realisation and awareness of the real world around us which is pretty cool."
Queenstown Climbing Club president Guillaume Charton said Sarah may be the youngest to make the summit.
Charton invited her to attend a club Youth Climbing Camp at Mount Cook at the end of the month.
