Jerusalem is an incredibly diverse city. There is a wide variety of things to see and so many areas of the city to explore. Almost every day, I try to visit a new area of the city after classes. I walk down the hill from campus to the bus stop and take either bus 19, 33, 44 or 74. Each one takes me to a different side of Jerusalem to see the new religious sites, museums or to try out a new cafe. I can even take buses all around the country; they leave regularly from the Central Bus Station in downtown Jerusalem.
Most people use the extremely reliable public transportation system to get around Jerusalem and around Israel. There are buses travsersing the city until two in the morning and the lightrail trains run through the center of Jerusalem until one in the morning. Taxis are overpriced, so it is rare to find a local using one. There are also some rideshare services, but few people offer rides through them.
When I first began to use public transportation in Jerusalem, the overcrowded buses and lightrail trains were overwhelming. I felt uncomfortable pushing my way through the crowd to find a place to stand. However, everyone does it.
