  The discovery of a light, singlet-like pseudoscalar Higgs boson, $A_1$, of
the Next-to-Minimal Supersymmetric Standard Model (NMSSM) could provide a
hallmark signature of non-minimal supersymmetry. We review here the potential
of the LHC to probe such a light $A_1$ in the decays of one of the heavier
scalar Higgs bosons of the NMSSM. We find the production of pairs of the $A_1$,
with a mass below 60 GeV or so, via decays of the two lightest scalar states to
be especially promising, for an integrated luminosity as low as 30/fb. For
heavier masses, the decay of the heaviest scalar into a $Z$ boson and an $A_1$
could lead to its detection at the LHC.
