Great Sand Dunes National Park is located 35 miles northeast of Alamosa, Colorado, reached by U.S. Highway 160 and State Highway 150 from the south, or from State Highway 17 and County Lane 6 from the west.
Note: Computer road mapping programs sometimes cannot fully distinguish types of roads or trails, and may route visitors via either Mosca Pass (hiking trail) or Medano Pass (high-clearance 4WD only). The only paved access to the national park is via the two routes listed above.
From Denver, Colorado Springs, or Pueblo, the most common route is south on I-25 to Walsenburg, west on US 160, north on State Highway 150. For a more mountainous drive from Denver (same mileage as the I-25 route), you may also take US 285 south, then State Highway 17 south, then County Lane 6 east from Mosca.
From Albuquerque, drive north on I-25 to Santa Fe, then north on US 285 to Alamosa. From Alamosa, take either U.S. Highway 160 east and State Highway 150 north, or State Highway 17 north and County Lane 6 east from Mosca.
