UCLA’s underground tunnel system, site of late-night forays by adventurous students and a subject of campus folklore, plays an important role in keeping the university running smoothly behind the scenes. The tunnel system transports steam created by a co-generation plant near Ronald Reagan Medical Center around campus, houses communications and chilled water transportation systems and accesses the underground portions of several campus buildings. Official tours of the underground tunnels can be arranged with Leroy Sisneros, UCLA Facilities Management’s Director of Maintenance and Alterations. Those touring the tunnels should wear closed-toed shoes and be advised that the tunnels are very narrow and hot in some places.
