There are several possibilities to account for the observed neutrino data in supersymmetric models. Often these models have much more parameters than there are observables in the neutrino sector and the quest arises to find further observables. I will discuss two scenarios where information can be obtained at future high energy collider experiments, e.g. the LHC or a future international linear collider. The first one is the general MSSM with conserved R-parity. Particular emphasis will be put on the question on how lepton number violation affects the analysis of lepton number conserving observables at the LHC. The second one is the MSSM with bilinear terms breaking lepton number and, thus, R-parity. Here the focus will be on: (i) generic predictions for the decay properties of the lightest supersymmetric particle in terms of neutrino mixing angles. (ii) Collider signals of gravitino Dark Matter.
