Lucien Abbet, better known as Lulu, is a pioneer of sport climbing and route-breaking in Valais. Although considered one of the best climbers of his generation in the field, his humility and his way of life have never been able to fit with the codes of public notoriety. Money, recognition, material goods have never interested him. He has devoted his entire life to his passion, a happy vagabond, as he likes to say: climbing and traveling.
