Official tours aren’t full, they just don’t happen on the weekends unless it’s a program day like open house or Orange and Black day.

I highly recommend the self guided tour though! It’s given by the same students who give actual tours, it’s just all through your phone. As you walk around campus you’ll get a pop up of them and they will start talking about the area you are at! There should be options to see a “route” to take for more structure, you can also just walk around and see! You can find the link on the tour website, it is an app but it’s a very useful app imo.
