Julia Bradbury is back! This time, she heads for Iceland to embark on the toughest journey of her life. Her challenge: to travel the entire 60 kilometres of Iceland’s most famous hiking route. It's an infamous trail, that just happens to culminate at the lip of the unpronounceable volcano which brought air traffic across Europe to a standstill in 2010.

With the help of Icelandic mountain guide Hanna, and precious advice from national experts, Julia faces the best, coldest, hottest, and most intimidating that the country's unique landscape and geology have to offer.

There are daunting mountain climbs, red hot lava fields, freezing river crossings, deadly clouds of sulphuric gas, swirling ash deserts and, of course, sinister Nordic ghost stories. Experience it all with Julia as she attempts to reach the huge volcanic crater at the centre of the Eyjafjallajökull glacier.
