Tehran

The best time to visit Tehran is during spring (March to May) and autumn (September to November) when the weather is mild and pleasant.

The top tourist attractions in Tehran include Golestan Palace, Azadi Tower, Milad Tower, National Museum of Iran, Sa'dabad Palace, and Niavaran Palace Complex.

The currency used in Tehran is the Iranian Rial. You can exchange money at banks, exchange offices, or some hotels. It's recommended to exchange money at official exchange offices rather than in the street to avoid scams.

The dress code in Tehran is modest and conservative. Women should wear hijab (headscarf) and loose-fitting clothing that covers their arms and legs. Men should avoid wearing shorts and sleeveless shirts.

Tehran has an extensive public transportation system that includes buses, taxis, and metro. The metro is the fastest and most convenient way to get around the city. Taxis are also widely available but make sure to negotiate the fare before getting in.
