Ed and comedian Rory Bremner explore one of the world's hidden skiing gems - Iran. Home to some of the best skiing in Asia, there is world-class skiing within 45 minutes of the capital. Graham and Ed also travel to Chile, where they trek up one of the country's largest and most active volcanoes - the 2847m Volcano Villarica. Despite hot lava rumbling beneath the surface the volcano is covered in snow, so Ed and Graham take full advantage to ski down - taking care to avoid the steaming crevasses.
