We investigate the possibility of probing high reheating temperature scenarios at the LHC, in supersymmetric models where the gravitino is the lightest supersymmetric particle, and the stau is the next-to-lightest supersymmetric particle. In such scenarios, the big-bang nucleosynthesis and the gravitino abundance give a severe upper bound on the gluino mass. We find that, if the reheating temperature is similar to 10(8) GeV or higher, the scenarios can be tested at the LHC with an integrated luminosity of O(1 fb(-1)) at root s = 7TeV in most of the parameter space.
