In the sixth episode Giles and Monica don their best thermals and extreme weather gear and travel 200km north of the Arctic Circle to Sweden's Lapland.
They enter a magical world of snow, ice, inky blue and pink skies - and Icehotel, a regular feature of bucket lists. Now in its 27th year, the hotel's team have given themselves their biggest challenge yet: to run an Icehotel that will stay open 365 days of the year, powered by the sun.
