The title of the video asks, "Most difficult landing in the world - Bhutan?" It certainly looks like it is a contender. The airport is Paro in Bhutan. Visual rules only, no instrument approaches. The pilots had to overfly the airport and head a up a valley where they did a tight 180 degree turn as they bled off altitude. Then there is a tight zig-zag to line up and drop onto the short runway.
Pretty much of a white knuckle ride. Then again, the bus ride there probably isn't any less terrifying.
