Abstract: The CRESST-II (Cryogenic Rare Event Search with Superconducting Thermometers) experiment, currently in its second phase, aims at the direct detection of WIMPs. Compared to previous runs the intrinsic radiopurity of CaWO$_4$ crystals and the capability to reject recoil events from alpha-surface contamination were significantly improved. Data from 29\,kg-days of exposure acquired by a single $\sim250$\,g CaWO$_4$ detector provide competitive limits on the spin-independent WIMP-nucleon cross section, particularly for low-mass WIMPs, and probe a new region of parameter space for WIMP masses below 3\,GeV/c$^2$.
