Bouldern
In short
Bouldern is the German word for bouldering, a form of free climbing performed on small rock formations or artificial walls without ropes.
In plain words
It involves climbing short routes called problems. Climbers use thick mats called crash pads to stay safe if they fall.
A simple example
A climber attempts to reach the top of a large granite rock in a park by using only their hands and feet. They do not wear a harness or use a rope.
Why it matters
It is a popular way to build strength and problem-solving skills. It is also a competitive sport featured in major climbing events.
Easy to mix up
Do not confuse it with traditional rock climbing, which uses ropes and harnesses for much higher walls.
