Ski Sunday's Ed Leigh travels the globe in search of the world's most unusual and exciting snowboarding destinations. Beginning in Moscow, Leigh jumps on the trans-Siberian railway en route to one of the world's coldest resorts, Sheregesh, before heading to Hokkaido in the north of Japan. He then moves on to the ultimate snowboarder's playground - the Himalayas. And after sampling the snow of the Atlas mountains, Leigh finishes his epic journey in the sand dunes of the Sahara.
