When visiting a college you would be remiss if you did not sign up for a campus tour. Campus tours are generally free, very broad and showy, student-led tours of a college campus. These tours are great for introductory purposes and to become familiar with the campus. Sometimes you will have the chance to speak to professors or administrative staff who can speak to some of the nice qualities of campus. That being said one must be cautious on the tours as you cannot take everything at face value. You should certainly talk to students you see milling around campus in order to ask them about how they feel about campus.
There are a couple of buildings you should try and visit when you attend a campus. First of all, if you have any inkling of an idea as to what you want to major in, you should visit that department's building as soon as possible. Visiting this building could give you a sense as to how important or active the department and its faculty are. Furthermore you should see if you can visit the dorm buildings of the campus. Sometimes during campus tours, your student guide might lead you through one of their buildings. Even if they do take you to one of their dorm buildings, try and visit one of their others to get a sense the community in the dorm buildings.
The most important building that you should visit is the school's cafeteria. The cafeteria and most importantly the food it serves can be an important factor in deciding whether or not to decide to go to a school, particularly if the institution forces you to sign up for one of their meal plans. You can also save yourself the trip and ask students about the food in the dining hall. If you get the opportunity to try the food for yourself, take it as it could be the food that you eat for the next four years.
Visiting a college campus is an important and exciting part of deciding where to go to school. It is important that you make the most of your visits and that you get a sense of what life on campus is like.
