Qurstion: I live in PORTO ALEGRE (BRASIL) and i intent to go to IRAN next NOVEMBER. My first goal is Theran (4 days) Dizin (2 days) Esfahan (2 days) and back to Tehran an go home..what i need to know is the price/rates of a BUS from tehran to Esfahan (roundtrip).

Answer: Every half an hour buses to Esfahan depart Tehran. It is a 5 hour drive. It is better to travel on the VIP buses with reclining chaires and larger leg rooms.
