Episode Information

Wildlife adventurer Nigel Marven is travelling over, 5000 miles, following grey whales as they undertake the longest mammal migration on Earth, up the Pacific coast of North America. From the warm winter birthing lagoons of Baja California, Mexico, a grey whale mother and her newborn calf must travel northwards to the icy seas of the Alaskan arctic. It’s a long, dangerous journey, past some of the world’s most breathtaking scenery; both under the water and above the waves. Up and down this coastline, Nigel meets whale-watchers and whale-worshippers, scientists and researchers - characters who share his love for these magnificent creatures. Along the way, Nigel also meets an amazing array of critters. On land, he finds snakes, bears, eagles and antelope, while out on the ocean waves he comes across a supporting cast of boisterous dolphins, playful sea lions, huge humpbacks and deadly killer whales.
