Hiking up Charter Hill from campus to the Big C is incredibly short and offers a nice view, especially at night. The Berkeley Online Tour of traditions mentions the C was built by moving the materials uphill in a human chain by the classes of 1907 and 1908. It also provides the "cheap seats" on Tightwad Hill that overlook the football stadium.
One (super intuitive, now that I think of it) caveat I feel I should mention is you probably don't want to be anywhere near a BBQ before climbing. The smoke from the grill will likely infuse a heavy meaty smell in your clothes, making you attractive to bugs of all sorts. .. either that, or I'm just that much more delicious than my fellow hikers.
