A free shuttle service is available between the Mount Scopus and Givat Ram campi; the shuttle operates only on days that there are classes, i.e., no shuttles on holidays and semester breaks. The shuttle leaves each campus every two hours and travels directly to the other campus. It is available Mondays to Thursdays during daylight hours. From the Mount Scopus campus, it departs from the bus terminal in the tunnel and the stop just outside Hadssah Hospital Mt. Scopus; on Givat Ram, first from the “Elef” (Lauterman) Dormitories and then from the Administration Building Gate.
