The nearest major airport is in Albuquerque. Santa Fe has very limited air service connecting to Denver that, so to speak, comes and goes; check the Santa Fe article for current status. No Interstate highways pass through the region, but I-25 skirts it on the southeast as it passes from the Colorado state line on the east side of the Sangre de Cristos, around Santa Fe, and on to Albuquerque. There is limited bus service to Santa Fe and Taos. A commuter train, the New Mexico Rail Runner Express (http://www.nmrailrunner.com/), connects the Albuquerque metro area to Santa Fe, with limited service daily. Fares are based on how far you ride, and a day pass will usually be in the range of $5-$9. Tickets can be purchased online (http://www.nmrailrunner.c...) or from ticket agents at the station and on the train. Amtrak's daily Los Angeles - Chicago Southwest Chief (http://www.amtrak.com/ser...) route serves North Central New Mexico with a stop in Lamy, about 15 miles south of Santa Fe on US Highway 285, and a shuttle that transports passengers between Lamy and Santa Fe.
