Bouldering, everyday more popular than the day before. Bouldering may be the purest form of climbing, but it is also the one with the most restrictions as almost everything is forbidden: you cannot use ropes, you cannot use carabiners, you cannot lean on a branch of a tree, you cannot place any protection ... you can only ...... climb. You, a crashpad and the rock. That's it, that's what we are looking for, isn't it? Strength, balance, technique, calm, just for the pleasure of ascending to a stone.
