Depending on what you want to do. Buildings are monuments are spread across the entire site in clusters. There are lots of trails. Reccomend go to visitor's center, pay the fee, see the movie and the electric map, then look around the museum portion. About 2hrs. Then you can drive to the various main points with some walking. Stone house is not always open. I'd say maybe 4 hours to see all the main points. If you want to hike trails, I'd plan differently, and figure on subsequent visits.
3 hours
From an hour to the whole day, depends on your interests and maybe the weather? Take your time, enjoy 😊
Depending on if you wish to see.both the 1st and 2nd Battle of Manassas sites or just one. Both are within the park but the main focus of the park is on 1st Manassas. A whole day is needed to see both but you can have a good visit of the main parts of the 1st battle sites in 2 to 3 hours.
All day
