The Museum Association of Taos (www.taosmuseums.org [1]) manages five museums in town, the Taos Art Museum at Fechin House [2], the Millicent Rogers Museum [3], the Harwood Museum of Art [4], the Ernest L. Blumenschein Home and Museum [5], and the La Hacienda de los Martinez [6]. At any of the museums, you can buy a $25 pass, valid for a year, that grants you a single admission to all five. With individual admissions costing $8 or more, it can be worth it if you visit three places.
The Governor Bent House [7] and the Kit Carson Home and Museum [8] are not included in the pass.
