There is a three dollar fee to use the park. You must go in the Visitor Center to pay. They will give a receipt you should keep on hand when in the park.
The Visitor Center has a small museum containing Civil War artifacts and a theater where you can watch a 45 minute park orientation film. The film shows every hour on the hour from 9AM until 4PM. If you can, watch it before you hike.
Along with this article, we have provided a map with some additional instructions for things to look out for. Transitioning between the First and Second Manassas Trails by the parking lot at Matthews Hill is particularly confusing. Check out the photos below for some important visual cues.
Even with our additional instructions, we suggest that you pick up maps and other brochures in the Visitor Center as they offer interesting historical information. The driving tour map is useful even if you are walking because it highlights the monuments.
A safety note. You will have to cross several roads on this hike. Cars on these roads are often travelling fairly fast, so if you have pets and/or children do not let them get too far ahead.
The hike has a few small hills, but nothing too awful. If you are okay with the distance, you should not have a problem.
Note that this hike does not take you to the Henry Hill House (highly recommended) or the Stone House. The Henry Hill House is located behind the Visitor Center and warrants a short walk to check it out.
You can drive to the Stone House by driving just north of the Visitor Center on 234 and then making a right onto 29 where you can access a parking lot. The House is clearly visible from the road.
