Top things to do
Self-guided ruins trail
A 1.2-mile interpretive loop through the standing adobe walls and chimneys of the second and third forts, the largest network of adobe ruins of its kind.
Santa Fe Trail ruts
Deeply worn wagon ruts of the Santa Fe Trail still cut across the prairie beside the fort, among the most visible trail traces anywhere on the route.
Visitor center museum and film
Exhibits and a film on frontier army life, the Santa Fe Trail, and the fort's role guarding the trail through the 1851 to 1891 era.
Make Self-guided ruins trail the timed anchor
Put the timed or highest-demand stop first, then keep the rest of the day close and low-friction. For one day in Fort Union National Monument, time Self-guided ruins trail first, then keep Santa Fe Trail ruts and Visitor center museum and film close enough that the visit still feels relaxed.
