I am planning to hike at the Jiankou section of the Great Wall. How can I get there from Juyongguan without going back to Beijing? Is there any public transport available from Juyongguan to Jiankou? Like the person before me, I would also like to cross to Mutianyu section and spend the night there after. Any recommendation for this route? Is it possible to see sunrise/sunset at this sites of the Great Wall? Thanks for any answers given.
