I want to know about local bus services in Guildford

There are two main bus companies operating in Guildford: Stagecoach and Safeguard. 

Stagecoach is the bus operator that runs a service through both the Stag Hill and Manor Park campuses, and across town with student discounts available

Safeguard operates a bus service via the Bellfields, Slyfield, Park Barn areas as well as Guildford town centre - they offer student discounts too.
