  The origin of galactic cosmic rays is one of the most interesting unsolved
problems in astroparticle physics. 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
$\gamma$ rays. Recent experimental results are presented and their implications
on the contemporary understanding of the origin of galactic cosmic rays are
discussed.
