Suggestions for Beginners:
If you have almost no experience climbing ice walls, attempting it alone can have serious consequences. Unlike beginner rock climbing, where most routes can be pre-equipped with top ropes, even the most basic ice walls often require lead climbing to set the route, and falling during ice climbing is very dangerous. Therefore, it is recommended that beginners go on their first few climbs with more experienced climbers to learn the basics (there are many techniques in ice climbing that differ from rock climbing); then try climbing independently.
Suggestions for Intermediate and Advanced Climbers:
If you want to tackle vertical ice walls, follow and follow some more before leading. Only start leading when you are fully confident. It might not be easy to find an experienced follower, but I believe the experts in our country are very willing to help. As long as you reach out and conditions allow, most people are happy to assist.
Climbing Precautions:
1. Always wear a helmet. Anyone approaching an ice wall must put on a helmet. And make sure it is UIAA certified (there was an incident before New Year's Day where a climber was injured after being hit, even though they were wearing a construction helmet).
2. Make sure your crampons are securely fastened (I often see climbers getting into awkward situations midway because their crampons come loose).
3. Always screw in your ice screws all the way. No matter how tired you are, this is one shortcut you can’t take. If there’s an ice bulge in the way of placing an ice screw, clear it with your ice axe and then continue screwing it in. (This is very important—half-screwed ice screws are dangerous due to their lever effect.)
4. Bring a headlamp. (Climbs often take longer than expected, and operating in the dark without a headlamp is dangerous and increases the risk of losing gear.)
5. Bring waterproof clothing. (Don’t overly prioritize athletic comfort by wearing stretchy clothes and pants. If you get soaked during the climb and then face strong winds, it could be life-threatening.)
6. Don’t step on the main rope. (It’s an old topic, but many climbers accidentally step on the rope, so be extra careful.)
That’s all I can think of for now. Feel free to add anything I’ve missed.
In short, safety first—progress gradually to truly enjoy the thrill of ice climbing.
