It is a week-long summer camp for under-served children from the greater Los Angeles area, with UCLA volunteer counselors. UniCamp runs for seven weeks throughout the summer at Camp River Glen in the San Bernardino National Forest. Because UniCamp is a non-profit organization, student volunteers from UCLA also fundraise money throughout the year to allow these children to attend summer camp. True Bruin Welcome begins the fall quarter to introduce new students to clubs and activities. The week includes the Day of Service for all freshmen, the Enormous Activities Fair, and the Sports Fair. At the end of move-in and the beginning of True Bruin Welcome, UCLA holds Bruin Bash, which includes a concert, dance and movie pre-release. Bruin Bash was created as a replacement for Black Sunday, a large-scale day of partying including all fraternities in North Westwood Village. The Pediatric AIDS Coalition organizes the annual Dance Marathon in Pauley Pavilion, where thousands of students raise a minimum of $250 and dance for 26 hours to support the Elizabeth Glaser Pediatric AIDS Foundation, Project Kindle, and the UCLA AIDS Institute.

In 2015, Dance Marathon at UCLA raised $446,157.
