Belen is just off Interstate 25, with three freeway exits. However, there are a couple of more scenic back roads that run parallel to I-25 east of the interstate. The nearest major airport is in Albuquerque.
Another great way to get to Belen is to take a train. A commuter railroad, the New Mexico Rail Runner Express (http://www.nmrailrunner.com), connects Belen to Albuquerque, Santa Fe and some of the other small communities along the Rio Grande. The Belen station is located near the intersection of Reinken Avenue and Wisconsin Street, across the railroad tracks from the Harvey House Museum putting you within walking distance of most of Belen's interesting sights. The train runs with limited service daily.
