Meet the toddler who has been climbing since she was 11 months old and can now scale 52-foot-high walls.

Isla Murr, four, started to climb things just two months after she started to walk at nine months old.

Mum Lucy Murr, 29, quickly noticed her daughter's unusual abilities for climbing and started taking her to playgrounds for older children.

Lucy, who lives in Sydney, Australia, said: "As soon as she learned to walk she's been climbing things.

"So when she was about 11 months I started taking her to older playgrounds so she could.

"She went to more advanced playgrounds for older kids. I'd say she's climbed all of the highest playgrounds they have in Sydney.

"I took her to playgrounds that have really high things to climb."

It didn't take long for Isla to become bored with playground climbing frames, so Lucy decided to introduce her to rock climbing.

Lucy said: "I showed her rock climbing videos on my phone and she just wanted to do that.

"She'd see videos of rock climbing and say I wanna do that, mum can I do that?

"One time there was a proper rock wall at some indoor playground we were at and she said 'mum can I go up there? I wanna go up there.'"

Unfortunately, no rock-climbing centres would allow young Isla to attend for safety reasons, so Lucy had to wait three years to finally let Isla explore her passion.

Lucy, a stay-at-home mum, said: "They wouldn't let her in because she was too young, which I understand, but I knew she could do it.

"I'd always tell her we have to wait until she's four and before she turned four she used to say 'when I turn four I'm going to go rock climbing.'

"She'd be disappointed and sad when I'd tell her she'd have to wait."

As soon as Isla turned four and became old enough, Lucy took Isla to a climbing centre and the little girl climbed everything she could.

She climbed all the kid walls first and quickly graduated to the adult walls, including a 52-foot-high wall.

Lucy said: "I had people around me saying 'wow, that's amazing!' There were kids that were about 12 saying that they wouldn't be able to go that high.

"We told her that she didn't have to go that high, but she just kept climbing."

Isla's performance didn't only shock the other onlookers, dad Brendon Murr, 34, a hydraulic engineer, was also surprised and squeamish at Isla climbing so high.

Lucy, said: "My husband was shocked, he didn't think she would get that high. I had to tell him to let her just go for it.

"I believe that a child will get more confident and better at things if you just let them do it."

Lucy is sure that climbing will be a lasting passion and thinks that Isla will go on to greater things.

She added: "She wants to go back again. I will definitely take her back wherever she wants to go with it we'll nurture it.

"The second we left she asked to go back to the rock climbing centre, and she's been asking a few times since.

"We'll probably take her about once or twice a month.
