Your list of specific places on campus will help guide your tour so that you get the most out of your campus visit. When I was visiting the colleges I applied to in my undergrad, I knew I wanted to see the university's dance studio, hockey arena, and library, so I made sure the tour guide took us there. If it wasn't part of the tour, I asked my Admissions Counselor how to get there and my parents and I toured it ourselves.
Depending on your prospective major, here are some places you may want to visit:

Also, don't just confine your tour to campus, be sure to take a drive through the town in which the campus lies. Check out the coffee shop, deli, bookstore, vintage shop, park, and the other interesting places in that town. This could be where you spend four or more of your "growing up" years, so not only are you marrying the college, but also the town it's in.
Your campus tour is the chance to see what you want and what is going to help you make your college search process easier and eventually help you make your admission decision, so make it yours!
