How safe is travelling overland in Iran?
The roads are asphalted and the maintenance is regularly done. There are highways in many routes and separate lanes to and from cities to safeguard transportations. As a matter of fact, contrary to many tourists' expectations, roads are of very good quality. If you choose to travel overland instead of taking a flight, you can see a lot of landscape, meet the people in the intact rural areas and experience the real life situations in addition to many other opportunities you will not find inside cities. For instance, Iranian guides can take possible opportunities to arrange picnic meals for you.
