updated tour times on the calendar. In the event of bad weather, please check the calendar or call regarding a scheduled tour time.

The tour is student-led and includes an outdoor walk(please dress appropriately)through Harvard Yard, providing a history of the university, general information, and a unique view on the students' individual experience. The tour is around one hour long, and completely free of charge. There is no pre—registration for general visitors, and we begin registration for each tour one hour before departure time. Currently we are only able to accommodate groups of up-to 14 people on our free, public tour. If you have a group of 15 or more, reservations are required (please see below).
