I visited the Great Wall December 30 2020. it was -12 degrees and windy. Due to the weather it was incredibly quiet which was magnificent but it was not pleasant feeling so cold. The wall is not a walk it is a climb. There are some very steep sections and the stairs can be a little daunting if you’re afraid of heights. standing at the top of the 8th tower is something special, looking into the distance at how far it stretches and the fact that people made this huge structure is mind blowing. I feel very accomplished for climbing the wall in the conditions I faced but I’m not sure I would recommend going during the same weather conditions but definitely make an effort to visit. Be sure to book online and it is much easier to get a didi to the wall as I tried getting the train to find I had no idea which train to take.
