We will begin our tour in the museum building on the site, which is located just to the southwest of the fort itself. If you are coming from the carpark, go through the modern tourist buildings managed by the National Trust and walk outside. A quarter-mile long path will lead you down into a valley and then up to the museum building managed by English Heritage. You will need an admission ticket to the fort, which you can acquire from either the National Trust or English Heritage staff, depending on your own membership affiliation. Tickets are between £4 and £7.
If you are coming from the Hadrian’s Wall path, leave the path and walk downhill along the western edge of the fort. You will come to the museum building.
