I am ecstatic to visit the Great Wall this month.

I will be traveling alone. So, I have many questions. I have read over some of the question and answer commentary that has previously taken place, but I still have a few questions.

First, Is there a bus that goes from the wall back to Huairou North Street? (My hotel will be in the Huairou district)

Also, Do I need to purchase a tour if I am traveling alone? I honestly would prefer to take in the experience alone.
