Not that I know of…
UF does have a one day event for “accepted” engineering students, in the spring.
If you need a more detailed tour, the individual colleges also do tours. I’ve done the engineering tour and I would recommend it.
Here’s a link to a few of them…
Engineering:

Business:

Journalism:

And of course, the honors college has a tour (“Afternoons with Honors”).

If you can’t find one, you can reach out to the individual college and ask them about tours or scheduling a visit with a someone from that department.
Good Luck!
