Booked a Grays tour to the Great Wall at Badaling. Enjoyable day, now when you get there you have the choice of heading to the steeper more popular section or the easier section the opposite way. Having gone both ways (the wall guys) i would suggest the easier section for anyone with leg,hip or heart problems, even this way is not an easy climb but you don't have so many groups wandering through, no matter which side you choose there will be hawkers trying to sell you everything cheap and fake. Watch out for Russian 20.00's given in change for 20.00 RMB notes too, looks similar but worth nothing. It's a long day and fun in the "peak hour" (when is it
never peak hour ) traffic on the way home, they will get you close as possible to your hotel on the way home but be prepared for this is as close as we can get and get dropped off a block and down the road.
