Great to see a small piece of significant history. Disabled access may not be the easiest attraction. Stunning scenery.

I would seriously highly recommend Jiankou Great Wall if you want to see a more genuine, unrestored section. It is relatively straightforward to get to (simply take the bus towards Mutianyu as far as Huairou then switch to the local bus H36 to Xizhazi Village (IMPORTANT: Not Jiankou Village as marked on Google Maps, this is the other side which is much steeper and more confusing - tried this route last year, got really lost and nearly fell off a cliff face...). Once you're off the bus, the path to the wall is tucked behind a row of houses - ask a local for directions if you're unsure. It's about an hour's walk through the woods to get to the Great Wall. The wall is absolutely stunning, you can see the trees growing up through the centre and lots of really picturesque spots (perfect for the Instagram haha!). Turn left when you get to the wall and it's about a three hour walk to Mutianyu. The path is challenging but not too hard - we were two young 20-somethings and did it in trainers, don't wear sandals/ heels! I'd only do this in good weather though, one part was REALLY steep and slippery, would definitely not be safe in winter. Once you reach Mutianyu, it's just a downhill walk through the restored section (maybe around an hour) to the exit, where you can then easily get buses back into Beijing.
