Watch Charley Boorman's Extreme Frontiers Season 2 Episode 2 Online

The intrepid traveller starts his second leg just south of Durban, where he tries his hand at surfing among some of the country's largest and fastest waves, before he and the team take a car up the treacherously steep and extremely icy Sani Pass, which connects Kwazulu-Natal and Lesotho. He then embarks on a challenging trek to the top of Tugela Falls - the world's second-highest waterfall - enduring biting winds before setting up camp on the summit.
