Nir Kumar Tamang was born in Solukhumbu in a poor family. He did not opportunities to get proper education and has to resort to manual labor from a small age to address the needs of this family.
His entry into the trekking sector was as a porter who would carry cooking stoves to trekkers' camp sites. Later he was promoted to a kitchen helper which required him to wake up the earliest of all and sleep at last.
Because of this lack of schooling, he had to work extra hard to improve his English skills. He did so by buying books and attending English lessons. His first trekking experience as a guide was the 12 days' Everest Base Camp trek. While on trek, he was asked by his guests about the garbage in the trails of Lobuche. He never forgets that one question and does everything from his side to keep trails clean.
He believes that the mountains of Nepal are extraordinary. He loves trekking the Annapurna and Everest for their sheer beauty and emotional connection. Nir Bahadur loves singing and dancing. He can play the traditional musical instruments flute and madal.
