I decided to end my summer trip in Beijing with a BANG! True enough, IT WAS! My friend and I decided to go to Mutianyu where the watchtowers and passes were built on the steep mountains (and what a climb it was!). Hiring a private taxi indeed was the best transport to take since it only took us a little over an hour. And it’s cheap! It’s a fast and easy way to get to the Great Wall if you want to spend a lot of time trekking the only man-made structure visible from space!
