Tehran Guide 2026: Current Situation, Heritage, Entry Rules & Safety

Tehran, Iran's sprawling capital, lies at the foot of the snow-capped Alborz Mountains, with Mount Damavand, the highest volcano in Asia, visible on clear days. It became the capital under the Qajar dynasty in 1786 and grew into a city of more than nine million people. Tehran is home to magnificent palaces, world-class museums holding Persian treasures, vibrant bazaars and a lively art and café culture. Iran itself has one of the world's oldest civilisations, with 28 UNESCO World Heritage Sites, including Persepolis, Isfahan and Yazd.

Do Not Travel (October 2026)

Iran is at war. Since 28 February 2026, the United States and Israel have carried out strikes on Iranian territory, and Iran has launched missile and drone attacks across the region. The western part of Iran's airspace is closed, and most Western governments advise against all travel and prohibit or warn their airlines against flying over Iran. Foreign nationals, especially dual nationals and citizens of Western countries, face a serious risk of arbitrary arrest and detention, which has been a long-standing issue. Consular help is extremely limited or unavailable. This article is provided for information and future reference only. Travel to Tehran is not currently possible or advisable.

Best Time to Visit Tehran

Under current conditions, there is no safe time to visit. For future reference, Tehran has a semi-arid climate: spring (April–May) and autumn (September–November) have pleasant temperatures of around 15–28°C and are the best seasons, summer (June–August) is hot, often reaching 35–40°C, and winter (December–February) is cold, with temperatures around 0–10°C, and ski resorts such as Dizin and Shemshak operate in the nearby mountains. Nowruz (around 21 March), the Persian New Year, is Iran's most important holiday.

Top Places in Tehran (Cultural Heritage)

The following sites are among the most important in Tehran. Their accessibility and condition may be affected by the conflict.

1. Golestan Palace

A UNESCO World Heritage Site, this Qajar-era palace complex is famous for its mirror halls, tiled façades and gardens.

2. National Museum of Iran

The museum covers Persian history from prehistoric times through the Achaemenid and Sasanian empires to the Islamic period, including artefacts from Persepolis.

3. Grand Bazaar

Tehran's historic bazaar is a labyrinth of corridors selling carpets, spices, copperware, gold and textiles, and it has long been a centre of commerce and politics.

4. Treasury of National Jewels

Housed in the Central Bank, it displays one of the world's most valuable jewel collections, including the Darya-ye Noor diamond and the Peacock Throne.

5. Azadi Tower

Built in 1971 to mark the 2,500th anniversary of the Persian Empire, this monument is a symbol of Tehran.

6. Sa'dabad Palace Complex

The former summer residence of the Qajar and Pahlavi rulers in north Tehran, set in a large park with several museums.

7. Tabiat Bridge

An award-winning pedestrian bridge connecting two parks, popular with locals in the evenings.

Also worth noting: the Carpet Museum, the Glass and Ceramics Museum, the Tehran Museum of Contemporary Art (with a major collection of Western modern art) and the Milad Tower.

Iran's Wider Heritage

Iran's highlights beyond Tehran include Isfahan, with its Naqsh-e Jahan Square and blue-tiled mosques; Persepolis, the ceremonial capital of the Achaemenid Empire near Shiraz; Shiraz, the city of poets and gardens; and Yazd, with its mud-brick old town and windcatchers. All are currently inaccessible to foreign tourists in practice.

Persian Culture

Persian culture has influenced the world for millennia through poetry, architecture, gardens, carpets, music and cuisine. Poets such as Hafez, Saadi, Rumi and Ferdowsi are still widely read and quoted in daily life. Persian carpets, gardens (bagh) and miniature painting are famous worldwide, and Iranian cinema has won major international awards.

A Brief History of Tehran

Tehran began as a small village near the ancient city of Rey, which was one of the great cities of the Islamic world until it was destroyed by the Mongols in the 13th century. In the Safavid era, Tehran grew into a walled town, and in 1786, Agha Mohammad Khan, founder of the Qajar dynasty, made it the capital of Persia. The Qajars built palaces such as Golestan, and under the Pahlavi dynasty in the 20th century, Tehran was rapidly modernised with wide avenues, universities and modern buildings. After the 1979 Islamic Revolution, the city continued to expand rapidly, becoming one of the largest metropolitan areas in the Middle East. Today, northern Tehran rises toward the mountains with leafy, affluent neighbourhoods, while the south contains the historic bazaar and older districts.

Iranian Gardens and Architecture

Persian gardens, laid out in the chahar bagh pattern with water channels dividing the garden into four parts, symbolise paradise and are recognised by UNESCO. Iranian architecture is famous for its turquoise domes, mirror mosaics (aineh-kari), muqarnas vaults and windcatchers in desert towns.

Information for Essential Travellers

Travel to Iran is not currently possible for most foreigners. Dual nationals and residents should follow their government's advice, register with their embassy where possible and maintain emergency plans.

Where to Stay in Tehran

No accommodation can be recommended for foreign visitors under current conditions.

Getting There & Around

Flights

Iran's airspace is partly closed, and most international airlines have suspended flights. Western governments advise against all travel. For general flight searches to other destinations in the region, you can use Aviasales, but travel to Iran is not currently possible or advisable.

Travel Costs

Iran uses the Iranian rial (IRR), and prices are often quoted in toman (10 rials). International sanctions mean that foreign bank cards do not work in Iran. Because travel is not currently possible, no reliable cost estimates can be given.

Visa & Entry Requirements

• Visa: Before the war, many nationalities could obtain an e-visa or visa on arrival, while US, UK and Canadian citizens had to travel with a licensed guide. These arrangements are not currently functional for tourism.
• Detention risk: Iran has a long record of detaining foreign and dual nationals, sometimes for years.
• Dual nationals: Iran does not recognise dual nationality and treats Iranian-born dual nationals as Iranian citizens.
• Consular assistance: Many Western embassies in Tehran have suspended operations.
• Insurance: Travel insurance does not cover travel to Iran against government advice.

Always check your own government's official travel advice for Iran.

Local Tips (For Future Reference)

• Hospitality: Iranians are renowned for their hospitality and the custom of taarof, a ritual of polite refusal and insistence.
• Food: Persian cuisine includes chelo kebab, ghormeh sabzi, fesenjan, tahdig (crispy rice) and saffron ice cream.
• Dress code: By law, women must wear a headscarf and loose clothing in public.
• Alcohol: Prohibited by law for Muslims and generally unavailable to visitors.
• Photography: Never photograph government or military sites.

The Current Situation

Since February 2026, Iran has been involved in a major war with the United States and Israel. Strikes have hit military, nuclear and infrastructure sites in Tehran and other cities, and Iran has retaliated against targets across the Gulf. The situation remains extremely volatile, with ongoing restrictions on movement, communications and air travel.

Tehran's Neighbourhoods and Daily Life

Before the war, Tehran's residents enjoyed a vibrant urban life. Families picnicked in parks such as Mellat and Jamshidieh, hikers set off on weekend trails at Darband and Darakeh in the Alborz foothills, and young people gathered in cafés, galleries and bookshops. Tehran's art scene included contemporary galleries, film festivals and theatre, despite censorship. Ski resorts such as Dizin, one of the highest in the world, were less than two hours from the city. The current conflict has severely disrupted daily life, with damage to infrastructure, restrictions on communications and widespread uncertainty.

Supporting Iran's Heritage

You can explore Persian art and history through museums such as the Victoria and Albert Museum in London and the Metropolitan Museum of Art in New York, which hold major Persian collections, and through Persian literature, film and music.
