You can co to the beach, surf, go to the boardwalk (which has rides, a decent arcade, minigolf, and lasertag), go bowling, go rockclimbing (indoor and outdoor), go to the movies, go eat at a restaurant, etc. Once you're 21 you can hit up the bars as well.

There are many active clubs, too many for me to name in fact. I know of a Film and Video series club, a Bike co-op, a Natural foods co-op, a hiking club, but there are many many more.
There are several UCSC newspapers/journals. The chief paper is City on a Hill Press, which serves as the traditional newspaper for the whole school. There are many others which serve as poetry journals, literary arts journals, and the like.
Many groups of people hang outside. Often I'll see people studying together in a quad, in a grassy knoll, or out on Porter meadow. People hang out and play frisbee, play guitar, and whatnot.

Each individual college has its own student covernment (Kresge Parliament, College 9 Senate, etc.), but there is also a student union assembly. I believe a freshman can join the student union assembly without participating in his/her own college's government, but I'm not entirely sure.
