WHAT IS BOULDERING?
Bouldering is a style of climbing exercised in short sequences of moves called problems.
It is also one of the simplest forms of climbing, done low enough to the ground to not require any special gear (no ropes), but a soft crash pad to fall on and climbing shoes to climb with.
"Solving" a problem often forces you to make unlikely movements such as hooking your heel ("heel hook") onto a hold or literally jumping from hold to hold ("dyno").
Bouldering is also one of the most social styles of climbing because it encourages people to gather around a boulder problem attempting to solve it and cheer each other on. The beauty of bouldering is that it can be done without a belayer and it doesn't require special climbing knowledge.
