While there are no formal tours of Apple's Infinite Loop campus or Apple Park, the company does offer a virtual tour of the facility at the Apple Park Visitor Center. Visitors can use an iPad to explore the campus in a virtual reality experience. The visitor center also showcases Apple products and includes a viewing area where visitors can see parts of the main building. 

Is there a different Apple store?
