UD offers a wide ranging variety of campus activities and clubs. Some of the most popular clubs are the athletic and religious clubs. There are also a number of fraternities and sororities on campus. UD's diversity allows you to join various clubs and become friends with an array of people.
Personally, I am involved with Air Force ROTC and intramural soccer. While Air Force ROTC is not a club per se, it allows students the opportunity to grow and develop as leaders for a possible career as a US Air Force officer. It requires one additional class, a Leadership Lab, and two one-hour Physical Training sessions a week. Intramural soccer provides a wonderful opportunity to play soccer with my buddies. We all played in high school and enjoy playing once a week for a month in a league. It's neither super intense nor competitive. Intramurals are more of a way to exercise, mess around with friends, and blow off stress. Incidentally, intramurals is where I met the majority of my closest friends.
Traditional events on campus are UD basketball games and Christmas on Campus. UD basketball games are a huge deal. The student section, named the Red Scare, uses student attendance at other sporting events as a point system for basketball tickets. For example, a UD soccer game is worth x points and your total points before the basketball season determine your student season tickets. Attend a lot of sporting events and order them quickly because they disappear fast! Christmas on Campus is another huge event. On the feast of Immaculate Conception, December 8th., there are no classes. On this day, students are able to "adopt" an inner city child for a day of fun, games, a ton of sugar, and presents. It's loads of fun and is a wonderful way of getting involved with the local community.
In terms of weekend campus activities, there are a number of parties at UD. It's a university and I'm not going to sugar coat to parents. Some people are really huge on the party scene and others not so much. I do not party a lot. I might go out with friends for an hour or two to a party but that is about it. There are dining options off-campus such as Panera, Chipotle, Pot Belly, Dewey's, and a few more. If you have a car, traveling to the Green for a day of shopping or dinning with friends is an option. It's a mall about 15 minutes from campus. Essentially, being bored at UD is impossible.
