One of the best things to do in Santa Fe for those intrested in art is go to the open galleries. There are some wonderful museums as well, but you can find artwork that is just as exciting, sometimes more valuable and more rare in the galleries. Some of the more important ones are on the streets surrounding the plaza. Each one has a specific range of works that they hold, from indian art to photography, modern paintings, etc. They tend to be more than happy to have people looking around.
