The hutongs are the historic heart of old Beijing. Join us on this 3km walk from the Drum Tower to the Tibetan Buddhist Lama Temple, through a winding labyrinth of alleyways and local color that takes you past some of Beijing's most ancient landmarks. IMPORTANT: There is a GPS offset in China, and as a result your position on Google and Apple maps will be incorrect. This issue doesn't affect the offline map, so after you've downloaded all the audio files, but before you hit start, switch to 'airplane mode' (or turn off data) and you'll be able to track your position correctly.
