It's the finale of The Travel Show special 'How Does a Blind Girl Go on Safari?'. Visually impaired Lucy Edwards makes her way to the Maasai Mara for 'The Great Migration', said to be one of nature's most spectacular events. In this episode, Lucy comes across the last line of defence against rhino poaching, hikes down to the foot of Thomson's Falls, and spends the day at a Maasai Village. But will she get the chance to experience one of the elusive river crossings where wildebeest risk their lives passing lions and crocodiles?
