Imagine you're playing with blocks and you stack them up really high to make a tower. Now, imagine that tower is made of huge rocks and it's taller than any building you've ever seen! That's called an alpine wall.
An alpine wall is like a really big, really steep mountain that people can climb up. These walls are made of rock and are located way up high in the mountains. They are really tricky to climb because they are so steep and can be really dangerous. People who climb these walls have to be very skilled and experienced climbers.
Climbing an alpine wall can take a long time and can be very hard work. Climbers use special equipment like ropes, hooks, and harnesses to help them move up the wall safely. They also have to be careful not to slip or fall, because if they do, they could get hurt really badly.
Despite the risks, climbing an alpine wall can be a very exciting and rewarding experience. The climbers get to take in incredible views of the mountains and the scenery around them. It's almost like being on top of the world!
