I review various search strategies for finding clusters at z > 1. Most efforts to date have concentrated on the environments of distant AGN. I illustrate these with data on the cluster around 3C 324 (z=1.2) and other, more distant systems, and discuss possibilities for future surveys with large telescopes.To appear in ``The Early Universe with the VLT,'' proceedings of the second ``Science with the VLT'' meeting held in Garching, Germany, on 1-4 April 1996.
