Around 4200, there is a slight altitude sickness, but it’s not a big problem, just keep warm. I didn’t even need oxygen.
The highest altitude is 4216 meters, depending on your physical condition.
The Pamir Plateau, with an altitude between 4,000 and 4,500 meters, usually has high altitude! But it has a lot to do with the region you go to. Among them, Konger Peak and Muztagh Peak are more than 7,000 meters above sea level, but ordinary tourists rarely go to this height. Unlike Tibet, the China-Pakistan Friendship Highway has convenient transportation. People with high fever can prepare oxygen bags and some commonly used medicines. Everyone’s physique is different, and the severity of hypertension is also different. It is best to be fully prepared, arrange your itinerary reasonably, adjust your diet, strengthen exercise, and most importantly, adjust your mentality. Finally, don’t forget to take some Omo brand blue nourishing tablets with you, and take them immediately if you have high reactions; I have taken them when I went to Tibet before, and the effect is still good. Some mountaineering adventure enthusiasts may also choose to climb mountains such as Muztagh Snow Peak and Konger Peak. At this time, they must ensure that they do not have symptoms of altitude sickness at lower places before arranging the climb.
The three relatively high places are all around 4,300, Muztagh, Panlong Ancient Trail, and Khunjerab. High reflexes vary from person to person. I had no reaction at Muztagh, and I had no reaction at the top of the Panlong Ancient Trail. My head was a little swollen at Khunjerab, but it wasn’t a big problem, and the glucose I prepared was useless.
