The biggest concentration of art galleries lies in the heart of Chelsea, west of Tenth Avenue. Start in the south, with 20th Street, and head northward along the parallel streets, up to 27th Street. At the more famous galleries, you might just come across a gem of a piece. But more generally, don't be afraid to stop by for just a brief look: what is interesting about the neighbourhood is that it offers a broad overview of contemporary art and its current trends.
