Fort Union National Monument is located in northeast New Mexico, about 35 miles north of Las Vegas and 24 miles north of Interstate 25. It sits on the Santa Fe Trail, a historic trade and transportation route connecting Missouri and Santa Fe during the 19th century.

The national monument preserves and interprets the remains of two military forts, which played a crucial role in the settlement and development of the western United States. Fort Union was initially established in 1851 as a military post to protect American interests in the region and to provide a supply hub for other military outposts. It served as a logistical center for troops, goods, and commerce for over 40 years.

The historical significance of Fort Union is tied to its strategic location along the Santa Fe Trail and its impact on westward expansion. The fort witnessed various military campaigns, including the Civil War, when it changed hands between Confederate and Union forces multiple times. However, it gradually became obsolete with the advent of the railroad in the late 19th century, and by 1891, the fort was abandoned.

Today, Fort Union National Monument offers visitors the opportunity to explore the preserved ruins of the fort. The main fort compound contains remnants of adobe walls, barracks, officers' quarters, and other structures. Interpretive exhibits and displays provide a glimpse into the daily life of soldiers stationed at the fort.

Exploring the fort's grounds and taking a self-guided tour are among the popular activities for visitors. The National Park Service also offers ranger-led programs and demonstrations during the summer season, providing insights into the fort's history and significance. Additionally, the monument features trails that allow visitors to explore the surrounding landscape and to appreciate the region's natural beauty.

Nearby attractions include Las Vegas, a historic town known for its Victorian-style architecture, where visitors can explore art galleries, museums, and charming shops. The nearby Pecos National Historical Park, located 25 miles south of Fort Union, offers further insights into the area's rich history, including the remains of Pecos Pueblo, a Native American village. Outdoor enthusiasts can also venture into nearby state and national parks, such as Storrie Lake State Park, offering opportunities for fishing, boating, and hiking.

Overall, Fort Union National Monument is a significant historical site that provides a window into the past, shedding light on the Santa Fe Trail and the military's role in westward expansion. Visitors can explore the ruins, learn about the fort's history, and immerse themselves in the vibrant surroundings of New Mexico's northeast region.
