Best Time to Visit:

Route and Accessibility:
Tehran has an extensive public transportation network with metro, buses, and taxis available. From Tehran, you can reach Tabriz by train, bus, or plane - it's around 600 km to the northwest. Rasht is about 4 hours north of Tehran by car.

Altitude and Acclimatization:
All of these cities are relatively low altitude. Tehran is the highest at about 1,200 meters.

Accommodation and Booking:
There is a wide variety of accommodation available from budget options to luxury hotels. Make sure to book in advance, especially during peak seasons.

Clothing and Essentials:
Iranian law requires women to wear a headscarf and loose, modest clothing. Men should also dress conservatively. Despite sanctions, the internet is accessible and fairly reliable, but you may want to download a VPN before leaving your home country.

Health and Safety:

Bring a basic first aid kit and any necessary medications. While Iran is generally safe for tourists, it's always wise to remain alert and aware of your surroundings.

Local Etiquette and Respect:
Iranians are known for their hospitality. Show respect by observing local customs and etiquette. Learn a few words of Farsi - your efforts will be appreciated! Always ask permission before taking photos of people.
