It is very difficult to park on campus if you don't get there before 9 a.m. on weekdays. So, if you live off campus, get there early, and if you live on campus, don't leave during the day or else it will be just as difficult to get your spot back. After about 3 p.m., the parking lots open up a bit, and it's a little easier to find a spot. A great deal at Regis is the public bus pass the University provides, which is helpful for getting downtown, especially on St. Patrick's Day for the downtown parade.
The newer parking lot on campus always has spots available, but the downside is that it is about an eight-minute walk to classes. The bus pass is an excellent way to get anywhere around Denver, but the most popular destination is downtown. The Denver public buses are safe and free for Regis students, so take advantage of this!
