Another walking programme, Julia Bradbury's Icelandic Walk, aired on 11 May 2011 on BBC Four. Her challenge was to walk the 60 kilometres of Iceland's most famous hiking route, which includes the newest hills on Earth. This route ends at Eyjafjallajökull, the volcano whose copious eruptions of volcanic ash brought air traffic across Europe to a standstill in April 2010. She also presented a new series in May 2011, following the routes of some of the UK's canals.
