About us Latest News Zipwirer's take to the air for little buds With trepidation and anxiety slowing giving way to adrenalin fueled exhilaration our flyers experienced the full effect of hurtling down 720 metres of Zipline at speeds of 50 mph! These brave souls have collectively raised over £1k for our @Darent Valley Hospital: Little Buds Fund with several saying they would be keen to experience ‘something like it’ again! A huge thank you to our eight daredevils and all who supported them!
