A selection of clusters in M33 is studied using three different observational techniques which give consistent quantitative results. M33 contains clusters which resemble galactic globular clusters as well as clusters as young as 10^8 years; the luminous clusters thus have an age range similar to those of the Magellanic Clouds rather than those of our Galaxy or M31. The four true globular clusters in our sample are all more metal poor than 47 Tuc. Based on limited data, the carbon star contribution to the integrated infrared light of the intermediate age clusters in M33 is approximately the same as in the intermediate age clusters in the Magellanic Clouds.
