  The Lightest Supersymmetric Particle (LSP) makes a good Dark Matter (DM)
candidate, since its relic density quite naturally comes out close to the
cosmologically required value. This is true even in minimal Supergravity models
with radiative symmetry breaking, which have a rather small number of free
parameters. On the other hand, the experimental detection of SUSY DM might be
quite difficult, necessitating km$^2$ size neutrino detectors or direct
detection experiments with several tons of detector material.
