Experimentally, the problem is attacked by a multi-disciplinary effort, namely by direct measurements of cosmic rays above the atmosphere, by air shower observations, and by the detection of TeV $γ$ rays. Recent experimental results are presented and their implications on the contemporary understanding of the origin of galactic cosmic rays are discussed.Invited talk given at the Roma International Conference on Astro-Particle physics (RICAP07) June 20th - 22nd, 2007.
