Tucson has an extensive public bus system operated by Sun Tran. The city also has a large network of bike routes and with its flat terrain is considered bike-friendly, but the heat makes this option less attractive in the summer months.The roads are easy to follow and driving is relatively pleasant, though the streets are congested at certain times of day. As with most cities in the US, things are fairly spread out and many tourists find it most convenient to hire a car, especially as so many of Tucson's top attractions are just outside the city.
