The daughter of polar explorer, Sir Wally Herbert, Herbert spent the first few years of her life living on a remote island in the Arctic with the Polar Inuit of Northwest Greenland. Her first language was Inuktun, the local dialect of Greenlandic. At the age of four Herbert accompanied her parents on a journey that took them through winter blizzards in a caravan to spend time with the Sami of Lapland. She has continued to travel extensively ever since.
After leaving school she studied Media & Design in Portsmouth, then went on to work as a fashion stylist for Japanese rock bands before becoming a travel writer and photographer for newspapers and magazines such as The Independent, The Sunday Times, The Daily Telegraph, Geographical and Traveller.
Herbert has appeared on several radio and television programmes, and presented a short documentary film about climate change for BBC Four in 2006. She has had solo exhibitions of her photography in the UK and Europe.
Herbert is Founder and Managing Director of Polarworld, an independent publishing company that specialises in producing books about the Polar Regions. Books published to date include The Polar World by Sir Wally Herbert, North-East Greenland - The Trapper Era by Peter Schmidt Mikkelsen and Face to Face: Polar Portraits by Dr Huw Lewis-Jones in association with the Scott Polar Research Institute, University of Cambridge.
