Mount Hua isn't the highest of the Five Sacred Mountains, but it's arguably the most precipitous. There's only one path up Mount Hua since ancient times, and the Thousand-Foot Cliff, Hundred-Foot Gorge, Azure Dragon Ridge, and Cloud Ladder are quite challenging. As someone with a fear of heights, I didn't dare try the Plank Road in the Sky or the Hawk's Turn.
Route: The classic "Northward Hiking + Westward Cable Car." The hike up the North Peak offers a sense of danger, while the West Peak cable car offers a beautiful view. The route is: Yuquan Temple → North Peak → Central Peak → East Peak → South Peak → West Peak. The section from Yuquan Temple to the North Peak is the most difficult, especially the Thousand-Foot Cliff and Hundred-Foot Gorge, which are steep and narrow, taking two and a half hours. The section from the North Peak to the Central Peak is the next most difficult, taking a little over an hour. The remaining East, South, and West Peaks are relatively easier.
Clothing: "Quick-drying underwear + windproof jacket and sweatpants + sneakers + sunglasses + hat" is sufficient. The weather has been particularly good these past few days; although it's windy at the summit, it's not cold.
Supplies: Don't bring too much food. Some beef jerky, chocolate, and sausages are enough; you won't have much of an appetite after climbing. Water is very important. I drank one bottle of water and four bottles of energy drinks throughout the trip. I brought three bottles with me. When I was close to the North Peak, I bought a bottle of Gatorade for 15 yuan (the shopkeeper said the price would go up after the North Peak). When I was close to the South Peak, I bought a bottle of Scream for 17 yuan (the price had gone up by 2 yuan, which was acceptable). There are many supply points along the way, so just travel as light as possible.
