Google headquarters, located in Mountain View, California, are open to the public, and wandering around the campus is a fun way to spend a few hours. Though there are no official tours and most of the buildings are only open to employees, visitors are more than welcome to walk around the grounds. While there, you have the opportunity to see many popular sights, such as the company’s unofficial T-Rex mascot statue, self-driving cars, and Android-themed art. If you know someone who works at Google, however, you might be able to arrange a tour of some offices to see the inner workings of the company. In any case, visiting the Google headquarters is a must for anyone.
