If you are undecided about which college to attend, a guided tour helps you get a feel for the school, its facilities and atmosphere. When you decide where to enroll, the first few weeks are busy getting to know professors and buying books. Getting a guided campus tour helps orient you on campus, saving you the stress of trying to get around. Guided campus tours are a great way to help you feel comfortable and ease your transition to a new campus.
Guided campus tours are easy to arrange, usually through the registrar's office. Many schools offer guided tours on a daily basis in the summer. If you have a large enough group, you could book a personalized tour. Some departments or faculties may offer guided tours tailored to their students' needs.
The downside of guided tours is that you are one person is a large group. It can be difficult to get the most out of the opportunity. Talk to the tour guide beforehand about the buildings you want to find. During the tour, don't be shy -- ask questions. Be sure to get a map of campus and remember a few landmarks. Even if you don't get to every building you want, wander campus after the tour and explore buildings on your own.
Most colleges offer guided campus tours in the summer when students are available and the campus is relatively quiet. The advantage of fewer students is you can explore campus without dodging people. The campus will be a lot busier during the school year. If you can do a tour while school is in session, you will get a better picture of campus life.
