Using the term "mountain" loosely, Star Dune a named, unranked summit in Alamosa County, Colorado, and resides within the Great Sand Dunes National Park and Preserve. Star Dune's elevation and precise location vary slightly with time as the wind continues to shape the dunefield. Latest measurements place Star Dune at an elevation of 8617', 1.40 miles due west of and with 277' of prominence to its parent summit, High Dune.

Most notably, Star Dune is identified by the National Park Service as the tallest dune in North America, measuring 750 feet (229m) from the valley floor to its summit. Despite being lower in overall elevation than High Dune, Star Dune earns the distinction of being the tallest dune in the park by earning an extra 100 feet of height as the valley floor slopes from east to west from High Dune.

There are other star shaped dunes in the park aside from this one. Created by complex wind patterns, star shaped dunes are radially symmetric with three or more arms radiating from the center of the mound. Star shaped dunes grow upward rather than laterally.

Getting There

Accessible from inside the Great Sand Dunes National Park and Preserve located in Alamosa County, Colorado, USA

Parking areas at the Visitor's Center and at the Dunes Parking Lot are good starting points for your trek to Star Dune.

There are no trails to the summit of Star Dune, so there a multitude of routes that you may take to it. From the Dunes Parking Lot, there are a couple of objective choices based on your goals for the day:

1] Star Dune via High Dune - Cross the parking lot and follow a sidewalk down to Medano Creek. Upon reaching the creek, cross to the other side. The highest visible dune immediately in front of you to the north is High Dune. Zig-zag your way up discontinuous ridgelines to its summit, approximately 1.15 miles from your starting point. From the summit of High Dune, look west and you will see the striking summit of Star Dune off in the distance, flanked by two smaller sub-summits.

The route you choose to reach its primary summit is yours, and depending on the efficiency of your route choices is approximately 1.40 miles away. Often, the most direct line is your best choice and you will ascend and descend several ridgelines along your way. The steepest portion of the climb will likely be the final ascent to the summit up the eastern side of Star Dune. This 30 degree slope can be an exhausting finish to your trek, but will soon be forgotten once you take in the views from the top. Return to the parking lot by reversing your route, or explore a new route on your own traversing due south of High Dune for an enjoyable loop hike.

Sand Dunes Route

2] Star Dune only - Cross the parking lot and follow a sidewalk down to Medano Creek. Upon reaching the creek, cross to the other side and then follow it west until you reach the base of Star Dune's more prominent N-S ridgeline. Follow the discontinuous ridgelines of your choice to the summit. Depending on the efficiency of your route selection, the summit of Star Dune is approximately 3.8 miles from your starting point. Return to the parking lot reversing your route, or make the trek 1.40 miles east to the summit of High Dune for a nice loop hike.

Hi HokieJim, I think that something may be wrong with the co-ordinates of this mountain. It's not in China, right?

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.



Parents refers to a larger category under which an object falls. For example, theAconcagua mountain page has the 'Aconcagua Group' and the 'Seven Summits' asparents and is a parent itself to many routes, photos, and Trip Reports.
