I'm going to assume that if you're looking into BYU, you have LDS standards. If you are coming to BYU expecting to have crazy parties, drinking, and clubs, you've definitely come to the wrong place. But as a person with LDS standards, the nightlife is great! You can always find something to do, whether it's on campus or around Provo. There are lots of great restaurants and activities to do. Driving and parking is probably the best transportation, but busses are available, or there are a lot of things within walking distance.
