Iran Travel Guide

Iran is the eighteenth largest country in the world, and inside its borders sit deserts, alpine ski slopes, subtropical Caspian rainforests, mangroves on the Persian Gulf, and a thousand-kilometer arc of UNESCO World Heritage sites. Most cultural itineraries follow the classical loop — Tehran → Kashan → Isfahan → Yazd → Shiraz — but the country rewards travelers who venture further: to the Armenian monasteries of West Azerbaijan, the ziggurat of Chogha Zanbil in Khuzestan, or the bazaars of Tabriz on the old Silk Road.

The best windows for a first visit are mid-March to late May (when Nowruz fills the cities and orchards bloom across the plateau) and late September to early November (clear skies, harvest, and comfortable desert nights). Summers above 40 °C are common in the southern deserts; winters bring snow to Tehran and the Alborz.

Of the world's recognised climate zones, eleven are found inside Iran's borders — from the humid subtropics of the Caspian coast to the hyper-arid badlands of the Lut, from alpine tundra on the Alborz and Zagros to mangrove swamps on the Strait of Hormuz. It is one of only a handful of countries on Earth where you can ski on fresh powder in the morning and swim in a warm sea by evening — and where, in any given week of the year, all four seasons are unfolding simultaneously somewhere on the plateau.

Spring (Bahār, late March – late June) opens with Nowruz at the equinox and turns the entire plateau into a corridor of blossom — pomegranate and quince in Yazd, sour-cherry and apple in the Alborz foothills, judas-trees on the slopes above Tehran. The wildflower steppes of Lorestan and the tulip fields of Kandovan are at their most extravagant. This is the classical season for travel: clear skies, snow still on the high peaks, rivers full.

Summer (Tābestān, late June – late September) divides the country in two. South of the Alborz, temperatures climb past 45 °C and the great deserts — Lut, Kavir — become impassable by day. North of the range, the Caspian provinces of Gilan, Mazandaran and Golestan stay green and humid, sheltered by the Hyrcanian forests, a 40-million-year-old relict of the late Tertiary recognised by UNESCO in 2019. Persians have summered on these shores since the Sassanian court; the rice paddies, tea gardens, and lagoons of Anzali are at their lushest now.

Autumn (Pāyīz, late September – late December) is the harvest season — pomegranate in Saveh, saffron in Khorasan, walnuts in Tuyserkan, dates in Bam. The northern forests turn copper and bronze; the desert nights are cool enough for camping under the milky way at Mesr and Shahdad. The grape harvest at Malayer and the rose-hip and barberry pickings of Khorasan fill the bazaars.

Winter (Zemestān, late December – late March) brings deep snow to the Alborz and Zagros. The resorts of Dizin, Shemshak and Tochal — all within two hours of Tehran — sit above 2,500 m and run from December to May; Dizin's top lift reaches 3,600 m, higher than almost any resort in Europe. Yalda, the longest night of the year, is celebrated on 21 December with pomegranates, watermelon and the poetry of Hafez, recited until dawn. While the plateau freezes, the Persian Gulf islands of Kish and Qeshm enjoy their best weather: 22 °C, dry, perfect for snorkelling.

""There is no country in the world where the traveller may pass within a few days from the snows of the high mountains to the date-palms of the south, from the rose-gardens of Shiraz to the salt-deserts of Khorasan.""

This climatic variety is reflected in Iran's extraordinary biodiversity. The country holds more than 8,000 plant species — over 2,000 of them endemic — alongside the Asiatic cheetah (now confined to the central deserts of Yazd and Semnan), the Persian leopard, the Caspian seal, brown bears in the Hyrcanian forests, and flamingos wintering on Lake Urmia and the lagoons of the Persian Gulf. Two UNESCO Natural World Heritage sites — the Lut Desert and the Hyrcanian Forests — and a UNESCO Global Geopark on Qeshm Island complete the picture.

The Safavid capital after 1598, Isfahan is built around Naqsh-e Jahan Square — at twenty acres, one of the largest urban plazas ever laid out, flanked by the Shah Mosque, the Sheikh Lotfollah Mosque, the Ali Qapu palace and the entrance to the old Qeysarieh Bazaar. The seventeenth-century traveler's proverb Esfahān nesf-e jahān — "Isfahan is half the world" — has outlasted every empire that produced it.

Allow at least three days. Beyond the square, walk the eleven historic bridges of the Zayandeh River — the Si-o-se-pol and Khaju are best at dusk — and detour to the Armenian quarter of New Julfa, where the Vank Cathedral preserves a remarkable fusion of Persian tile and Christian iconography.

Shiraz is the city of Hafez and Saadi, and Iranians still come on weekends to read aloud at their tombs. The Eram and Narenjestan gardens preserve the Persian chahar bagh ("four gardens") template that travelled east to Mughal India and west to Moorish Spain. Don't miss the rose-and-stained-glass interior of Nasir al-Mulk Mosque at sunrise, when the prayer hall fills with shifting pools of color.

From Shiraz, day-trip an hour northeast to Persepolis — the Achaemenid ceremonial capital begun by Darius I around 518 BCE — and to nearby Naqsh-e Rostam, where the rock-cut tombs of Darius, Xerxes and Artaxerxes loom above Sasanian victory reliefs. A further forty minutes brings you to Pasargadae, where the stepped tomb of Cyrus the Great has stood alone on the high plain since 530 BCE.

Listed in 2017, the historic city of Yazd is the best-preserved example of mud-brick urbanism on earth — a labyrinth of vaulted alleyways, courtyard houses cooled by badgirs (windcatchers), and underground qanats that have brought water from the mountains for two and a half millennia. Yazd is also the heart of surviving Zoroastrian Iran: the Atash Behram temple keeps a sacred fire reportedly burning since 470 CE, and the Towers of Silence stand on the desert edge.

A half-day north of Isfahan or south of Tehran, Kashan is the elegant first or last stop on the loop. The merchant houses of Tabatabaei, Borujerdi and Ameri — each built around sunken courtyards, wind towers and reflecting pools — capture nineteenth-century Qajar domestic life. Just outside the city, Fin Garden (UNESCO, 2011) is the oldest surviving Persian garden in Iran, fed by the spring that has watered it for five centuries.

Most journeys begin in Tehran. Spend a day on the Golestan Palace, the National Museum (proto-Elamite tablets, the bronze Parthian prince), the Carpet Museum and the contemporary galleries of the Tehran Museum of Contemporary Art — which holds one of the great twentieth-century Western collections outside Europe and North America.

North of the Alborz range, the Caspian provinces of Gilan and Mazandaran are humid, green, and famous for rice, tea and the Hyrcanian forest — a Pleistocene relict woodland inscribed by UNESCO in 2019. In the northwest, Tabriz centers a covered bazaar so large it is itself a World Heritage site; from there it is a few hours to the Armenian monastic ensembles of St. Thaddeus and St. Stepanos.

Spread across the southern foothills of the Alborz at 1,200 metres, Tehran is a city of fourteen million pressed between snow-capped peaks and the high plateau. The capital since 1786, it preserves an extraordinary chain of royal compounds — three open as museums — that together trace the Qajar and Pahlavi centuries from courtly miniature painting to mid-century European modernism.

Begin at the Golestan Palace (UNESCO, 2013), the Qajar court complex whose mirrored halls, painted ceilings and tiled garden façades distill the entire nineteenth-century encounter between Persian and European decorative arts. The Marble Throne hall — carved from a single block of Yazd alabaster — is one of the great surviving thrones of the Islamic world.

North of the bazaar, in the cooler hill suburbs of Shemiran, two later royal estates open as museum-parks. Saadabad spreads across 110 hectares of plane and cedar forest and contains eighteen palace pavilions, including the Green Palace of Reza Shah and the marble White Palace of his son. A few kilometres east, Niavaran was the last residence of Mohammad Reza Shah and Empress Farah Pahlavi — the family quarters left almost as they were on the day they departed in January 1979.

For a modern panorama, ride the Tochal gondola to 3,740 metres — one of the longest cable cars in the world — or take the lift up the Milad Tower, the sixth-tallest telecommunications tower on earth, for sunset over a city ringed by snowy peaks.

Cross the Alborz from Tehran and the climate changes within a single hour: dry plateau gives way to terraced rice paddies, tea plantations, and the ancient Hyrcanian forest — a 25-million-year-old relict woodland of oak, beech and ironwood that runs in a narrow green band along the southern Caspian. In Gilan, the stepped honey-colored village of Masuleh climbs a forested mountainside so steep that one house's roof is the next house's courtyard.

Further east in Mazandaran, the Belle-Époque resort of Ramsar sits between snow-capped peaks and the sea, and the high-altitude village of Filband floats above a sea of clouds at dawn. Inland, the Alamut Valley in Qazvin province hides the cliff-top ruins of the Assassins' castles — a two-day trip from Tehran rewarding hikers with some of the most dramatic mountain scenery in the country.

Tabriz, capital of East Azerbaijan, sits on the old Silk Road and was the Safavid capital before Isfahan. Its Grand Bazaar, the largest covered bazaar in the world, was inscribed by UNESCO in 2010 — a labyrinth of vaulted brick caravanserais, hat-makers' alleys, and the still-thriving carpet trade for which the city has been famous for seven centuries.

An hour south, the troglodyte village of Kandovan is one of only three inhabited cave-village complexes in the world (alongside Cappadocia and Dakota's Mesa Verde) — cone-shaped homes carved from volcanic tuff still housing families seven centuries on. Push northwest toward the Turkish border for the ninth-century Armenian monasteries of St. Thaddeus (Qareh Kelisa) and St. Stepanos, jointly inscribed by UNESCO in 2008.

The southern coast is the warm, humid, palm-fringed Iran of dhow ports and pearl divers — a world apart from the high plateau. From Bandar Abbas, ferries reach the geological wonderlands of the Gulf's islands. Hormuz Island is famous for its red-soil "edible mountains," rainbow-colored mineral cliffs, and a beach where the waves break iron-red against turquoise water.

Larger Qeshm Island — the biggest island in the Gulf — holds Iran's first UNESCO Global Geopark, with the sculpted slot canyons of Chahkooh, the Stars Valley badlands, and mangrove forests at Hara where flamingos winter. Further west, Kish Island is the duty-free leisure island for domestic travelers, with snorkeling reefs and the underground Kariz aqueduct city.

On the mainland coast, the old port of Bushehr preserves a quarter of nineteenth-century Gulf-Arab merchant houses built from coral stone, and the palm groves of Minab still host the great Thursday market where Bandari women trade in the burqas of the Strait of Hormuz.

Between Kerman and the Afghan border lies the Dasht-e Lut — inscribed by UNESCO in 2016 and, for several years in the 2000s, the hottest measured place on Earth at 70.7 °C. Its kaluts are wind-sculpted mega-yardangs up to forty kilometers long, lined up like the hulls of stranded ships. The classic entry is from Shahdad, an hour east of Kerman, where small lodges arrange 4×4 trips into the dunes at sunset.

In Isfahan province, the desert oases of Mesr and Garmeh offer the gentler experience — camel treks, sand-board dunes, and traditional khaneh guesthouses under skies as dark as any on the planet. Near Kerman city, the lush Mughal-style Shazdeh Garden in Mahan is the most unexpected sight in Iran: a green geometric paradise rising abruptly from the desert floor.

Iran's second city and holiest pilgrimage destination, Mashhad grew around the tomb of Imam Reza, the eighth Shi'a Imam, martyred in 818 CE. The Holy Shrine complex covers nearly a square kilometer — a luminous city-within-a-city of mirrored halls, gilded domes, and seven vast courtyards that together receive more than twenty million pilgrims a year. Non-Muslims are welcome in the outer courtyards with a guide.

From Mashhad, the old Silk Road runs west through Neyshabur — the city of Omar Khayyam and Attar, set in turquoise mining country — to the brick caravanserais of the Khorasan steppe. To the south, Tus holds the monumental tomb of Ferdowsi, author of the Shahnameh; to the northeast, Kalat-e Naderi is a natural fortress-valley ringed by sheer cliffs, once the personal stronghold of Nader Shah.

South of the Lut, the citadel of Arg-e Bam — the largest adobe complex in the world — was painstakingly rebuilt after the 2003 earthquake and inscribed by UNESCO the same year. Two hours away, the troglodyte village of Meymand has been carved from soft volcanic tuff for at least three thousand years and is still inhabited by semi-nomadic shepherds whose calendar follows the transhumance of their flocks.

Far to the south-east, on the Sistan plain, the Bronze-Age Shahr-e Sukhteh ("Burnt City") yielded the world's oldest known artificial eyeball and an animated cup whose painted goat appears to leap when the cup is spun — proto-cinema from 3200 BCE.

The plains of Khuzestan hold two of the oldest continuously inhabited sites on earth. Susa, occupied since 4200 BCE, was an Elamite, Achaemenid and Sasanian capital in turn; nearby Chogha Zanbil is the best-preserved ziggurat outside Mesopotamia, built around 1250 BCE by the Elamite king Untash-Napirisha and the first Iranian site inscribed by UNESCO (1979).

North of Tehran, the Mongol-era Dome of Soltaniyeh in Zanjan province stands forty-nine metres tall and is the third-largest brick dome ever built — a direct ancestor of the great Timurid and Mughal domes of Samarkand and Agra. Continue east to the Caspian via the lagoon-port of Bandar-e Anzali and the historic walled city of Qazvin, briefly a Safavid capital under Shah Tahmasp.

Western Iran is the Iran of the ancient Medes and the great rock reliefs of the kings. Hamadan, ancient Ecbatana, holds the rock-carved Median tomb of Esther and Mordechai and the eleventh-century tower-tomb of Avicenna. South in Kermanshah, the trilingual cliff-face inscription of Bisotun — Darius the Great's 520 BCE résumé carved 100 meters above an old caravan road — was the Rosetta Stone of Old Persian cuneiform.

Further north, the Sasanian relief galleries of Taq-e Bostan are set inside a cliff-cut iwan beside a spring-fed pool — a perfect afternoon stop. And in Lorestan, the steep gorges of the Zagros mountains still shelter semi-nomadic Bakhtiari herders moving their flocks each spring on one of the longest seasonal migrations in the world.

Most nationalities can obtain a visa on arrival at Imam Khomeini International Airport (IKA) for 30 days, with prior authorization code arranged through a licensed Iranian agency. A small number of passport holders (including U.S., U.K. and Canadian citizens at the time of writing) must travel on a pre-arranged guided tour. Always check current advisories before booking.

International bank cards do not work in Iran due to sanctions: bring euros or U.S. dollars in cash and exchange at official sarrafi bureaus, or use a prepaid local tourist card. Tipping is modest and not expected in restaurants, but always welcome from porters and drivers.

"Mehmān habib-e Khodāst — the guest is the beloved of God."

Dress: women must cover their hair with a loose scarf in public and wear a long tunic over trousers; men should avoid shorts in cities and shrines. Ta'arof — the elaborate Persian etiquette of polite refusal — will follow you everywhere; when a shopkeeper waves away your money, smile and insist twice before paying.

Few countries pack as much landscape diversity into a single border. In a single 24-hour drive you can pass from the subtropical Caspian rainforest (annual rainfall 2,000 mm, palm trees and rice paddies), over the snow-capped Alborz at 5,610 m on Mount Damavand (Asia's highest volcano), across the central plateau steppe (cold winters, hot dry summers, the cradle of qanāt agriculture), into the salt deserts of Dasht-e Kavir and the dune seas of the Lut (where MODIS satellites have recorded the hottest land surface temperature ever measured, 70.7 °C in 2005), and finally down to the mangrove-lined coast of the Persian Gulf and the coral islands of Hormoz and Qeshm. The 2 percent of Iran's territory under forest holds an estimated 13,000 plant species, of which more than 2,500 are endemic — a higher endemism rate than continental Europe.

Iran is at its best in two narrow windows: late March to mid-May (post-Nowruz, when the country is in flower from the Gulf almond orchards to the Alborz tulip fields) and late September to early November (the date and pistachio harvest, mild plateau weather, the Mehregan autumn festival). Summer travel in the central deserts demands acclimatisation; winter in the northwest can mean −20 °C in Tabriz and metres of snow on the Sahand and Sabalan massifs. The Nowruz holidays themselves (21 March – 2 April) double domestic hotel prices and book out the desert ecolodges twelve months in advance.

Citizens of 47 nationalities can obtain a 30-day visa on arrival at IKA, Mashhad, Isfahan, Shiraz and Tabriz airports; the list includes most of the EU, the UK, Switzerland, Norway, China, Japan, Brazil and Mexico — but excludes US, UK, Canadian and Israeli passport holders, who must pre-arrange an authorisation code through a licensed Iranian agency and (for the first three) travel only with a guided itinerary. The currency is the Iranian rial but everything is priced in tomān (1 tomān = 10 rials), and prices are usually quoted with three zeros lopped off; cash is king because international cards do not work. Bring crisp euros or US dollars in small denominations. SIM cards are sold at the airport for under USD 5; Irancell offers 30 GB of 4G for roughly USD 4/month.

Each Iranian city has a dish you are expected to eat there. In Tabriz it is kufteh tabrizi, a single rice-and-meat ball the size of a grapefruit; in Isfahan, biryāni (lamb hash, not Indian biryani); in Shiraz, kaleh-pācheh at dawn (sheep's-head soup), with fālūdeh shīrāzi for dessert; in Yazd, the marathon shīrīnī circuit of baqlavā, qottāb and pashmak; in Bandar Abbas, ghalyeh māhi (tamarind-and-coriander fish stew); in Tehran, the late-night jegar (grilled liver) carts of Tajrish. Vegetarians do well: every restaurant serves kashk-e bādemjān (whey-and-aubergine dip), mirzā ghāsemi (smoked-aubergine omelette) and āsh-e reshteh (herb-and-noodle soup).

Iran's tourist infrastructure outside the half-dozen big cities runs largely on family-owned guesthouses (eqāmatgāh-e būmgardī) — restored caravanserais, qanāt-cooled adobe houses, nomad black-tent camps in the Zagros. Booking through these operators rather than international chains keeps revenue local. Water is the scarcest resource: a single hotel shower in Yazd consumes roughly as much water as a desert household uses in a day. Carry a refillable bottle (tap water is potable in every major city), avoid single-use plastics on desert trips, and never collect pebbles, shells or pottery sherds — the latter is a criminal offence under Iran's antiquities law.

Iran's 31 provinces span eleven climate zones and four millennia of continuous settlement. The table below lists the most-visited provinces with their capital city, signature UNESCO sites, and the best season for a first visit.
