Fort Union National Monument
RV Guide


The Fort Union National Monument was established in 1954 to preserve the 19th century Fort Union in Mora County, New Mexico. It is administered by the National Park Service, and while there is no camping at the monument, there are nearby government run campgrounds to the west in the Santa Fe National Forest, and a KOA a short drive south with full amenities.

Historically were three forts in the park area constructed in 1851. The Fort Union National Monument has the remains of the second fort and the ruins of the third fort, as well as traces of the Mountain and Cimarron branches of the old Santa Fe Trail.

The park is situated in a windswept valley with prairie grass stretching out around it.

The site occupies over 700 acres and has a visitor center set at an altitude of 6760 feet with a 1.2 mile trail winding through the ruins of the old adobe forts. The visitor center has restrooms, a large exhibit area, and a short movie providing information on the historic fort and surrounding natural areas. Discover the cultural and military history of the fort and Santa Fe Trail by touring the preserved remnants of the structures, and the remaining wagon trail ruts of the Santa Fe trail while taking in the natural beauty of the surrounding countryside. Mountains soar above the horizon to the west. Pets are allowed on a leash at this national monument.

Seasonal activities in Fort Union National Monument


Historical Tours

The Fort Union National monument has a 1.2 mile self guided interpretive trail for visitors to use while exploring the historic fort. A shorter 0.5 mile walk will take visitors through a portion of the old fort, and is ideal for those who find the longer trail too strenuous.

The Fort was used for both military and logistical functions, serving as storage for local installations and operations, and providing escorts for mail stagecoaches and travelers. Rangers provide guided programs and answer questions about the 19th century fort and the wagon trains that once used the historic Santa Fe trail.


With an excellent view of the night sky, and minimal light noise from surrounding civilization, many stargazers enjoy the natural setting and the historic fort to engage in a little amateur astronomy.

Throughout the year, several presentations are held to learn about the night skies over Fort Union, and tour the fort by moonlight. For some presentations telescopes are provided, or you can bring your own, and a star chart, to discover the night sky from this beautiful location. Cellular service is spotty, so don't rely on cellular phone apps, bring printed star maps. Check the monument website for dates of organized stargazing presentations.



Many of the hiking trails in the nearby canyons, mesas, and mountains can be used by cyclists. Mountain bikes outfitted to handle the terrain and rough ground in these natural areas are required. Remember to ensure you have appropriate safety equipment including a helmet.

On multi use trails, use caution and watch for foot traffic. The numerous trails in the area provide excellent views and beautiful scenery to enjoy while cycling in the area but also involve elevation changes so ensure they are appropriate for your ability level before setting out.



Hikers can experience a variety of natural landscapes in the Fort Union area. From grasslands, desert, mesas, and canyons, to the mountains of the Santa Fe National Forest to the west, there is plenty of natural beauty to take in.

The mountains offer miles and miles of trails, and well-marked trailheads, providing access to scenic wilderness areas. The elevations on these mountain trails provide fantastic vistas looking out over the flat desert and prairie grasslands. Treed and forested trails are cool for hiking in warm weather. Fall is a great time to head out on a hike, when bugs are less prevalent, and temperatures are cooler.


Downhill Skiing

During the winter, couple a trip to Fort Union with a little downhill skiing at one of the many ski resorts to the west, in the Santa Fe National Forest's mountainous areas. About three different ski resorts are just a short drive away.

Winter driving conditions in the mountains from Fort Union can be difficult so check weather forecasts prior to setting out.

Enjoy the scenic mountains and the wilderness area while gliding around set ski tracks. It's a great way to enjoy the wilderness area even during the off season. Be sure to dress in layers you can shed as you warm up with activity and can put back on to stay warm at rest stops. Weather permitting, you can even arrange to rent a yurt in winter months for an overnight stay.
