My biggest concern was altitude sickness, but the entire trip went well, and I didn't feel anything. This might be because we had oxygen tanks, and for higher altitudes, the travel agency arranged oxygen rooms, which was a really great touch!
Itinerary: On the day we explored Daocheng Yading, it's essential to bring an oxygen tank. You'll definitely feel a difference in your heart and lungs, and the climb can still be a bit challenging; however, I thought the scenery was decent. The night sky was truly beautiful, and you could see the stars clearly with the naked eye, no telescope needed. Personally, I prefer Mount Siguniang over Daocheng Yading; the scenery at Mount Siguniang is lusher and more diverse!
Driver: The driver was excellent, drove steadily, and had a mild temperament. He was punctual every day and shared interesting local customs and stories with us along the way.
