Request a Security Escort
The complete schedule for Cliff Shuttles can be found at the Transportation and Parking website. There is also a link to "Where's Cliff" that will provide you with near real-time location of the shuttles that are running.
If you need a secure escort, as opposed to riding a shuttle, you can call 404-727-PARK (404-727-7275). The Emory Police Department coordinates and dispatches security escorts.
