If you are taking the official "Warner Bros. Studio Tour London - The Making of Harry Potter" branded bus, there are three main departure points in central London as of 2026. The primary and most frequent stop is at Bulleid Way in Victoria (near Victoria Station). Additional pick-up points are located near Baker Street Station (typically on Marylebone Road) and at King's Cross Station (Bus Stop T on Pancras Road). These buses are operated by partners like Golden Tours and are easily identifiable by their massive Harry Potter themed wraps. If you are traveling independently via rail, you must take a train from London Euston to Watford Junction. From there, a dedicated (and free for ticket holders) shuttle bus runs every 15 minutes directly to the studio entrance. It is highly recommended to arrive at your London bus stop at least 15-20 minutes before your scheduled departure, as the coaches must leave on time to ensure you reach your specific tour time slot.
