By bus
There is limited Greyhound service to Santa Fe and to points in southern Colorado. The Town of Taos operates the Chili Line local bus system including ski season service to Taos Ski Valley. Faust Transportation 575-758-3410 provides local taxi, regional and airport shuttle, and charter bus service to the North Central NM area. Its airport shuttle is no longer operating. Twin Hearts Express Shuttle Co. 575-751-1201 also provides shuttle services to and from the Taos area. The North Central Regional Transit District (http://www.ncrtd.org/) "Blue Buses" provides free bus service Monday through Friday with routes that connect the counties and communities of Taos, Santa Fe, Los Alamos and Rio Arriba.
By car
Taos' position on the west slopes of the Sangre de Cristo Mountains restricts road access somewhat, as there are few passes through the mountains and the ones that exist may be closed in the winter due to snow. Coming from Denver and other points north, there are two options: either follow Interstate Highway 25 to Raton and then US Highway 64 over Palo Flechado Pass and into Taos, or follow Colorado state road 159 south to the New Mexico border, at which point it becomes New Mexico state road 552 and continues to Taos.
There are also two routes into Taos from Santa Fe and Albuquerque. The most direct route follows US Highway 285 through Pojoaque to Española, then New Mexico state road 68 along the banks of the Rio Grande to Taos. There are a number of scenic viewpoints on this road; it's worth stopping to see if river runners are on the Rio, particularly during high water spring at which time this stretch of river is one of the finest whitewater experiences in the continental United States. The slower and higher, but even more scenic, "High Road to Taos" diverges at Pojoaque and first follows New Mexico 503 to Chimayo, then New Mexico 76 becomes 75 to Peñasco and New Mexico 518 to outlying Ranchos de Taos and finally Taos itself. This is a beautiful drive in the spring and summer; the Sangre de Cristos are snow-capped until June or so, while later in the summer, the thunderstorms that build over the mountains provide a different kind of elemental beauty.
