Ms Barr was a long-standing member of Girlguiding, receiving her 10-year service award in 2020.
“Beccy was inspirational in everything that she did. She was so much fun, she had so much energy she was so inspiring,” Ms Hunter added.
“She really was an ambassador who just showed every girl in Girlguiding that they could do anything they put their mind to.
“It’s so very sad we’re so upset here at Girlguiding NWE and just want to send loads of love and condolences to her friends and family.”
Former rugby league player, Adrian Morley, climbed Mount Kilimanjaro with Ms Barr in 2015 for charity.
Ms Barr covered the challenge for North West tonight – taking part in the Guinness World Record for the world’s highest game of rugby.
“Out of all the parties she probably did it [the climb] the easiest,” Mr Morley said.
“She was brilliant, full of energy, full of life, full of zest. She left us in slip streams when we were climbing.
“She was great, a great member of the team, great fun. I just remember great, great moments and great company.
