The most hospitable road in the world
Ask anyone who has backpacked Iran what they remember and they will not start with the mosques. They will start with the people: the family who insisted you join their picnic, the carpet seller who talked history for an hour with zero intention of selling you a carpet, the students queuing to practise English on a bridge at midnight. The classic north–south line — Tehran, Kashan, Isfahan, Yazd, Shiraz — stacks two millennia of architecture along one bus route, and the hospitality fills every gap between cities. Two weeks is the minimum that does it justice.
Before you go
Most nationalities need a visa arranged in advance (e-visa or visa on arrival with pre-approval; check current rules for your passport, as they shift). Two hard practicalities define travel here in 2026: foreign bank cards do not work, so you carry your entire budget in cash (euros or dollars) and change as you go — or load a local tourist debit card on arrival; and the exchange rate moves constantly, which for travellers has generally meant Iran is astonishingly cheap. Figure $25–40 a day staying in traditional guesthouses. Women must cover hair and wear loose clothing in public; pack a scarf and long layers. Download a reliable VPN before arrival, and get the local apps — Snapp (ride-hailing) makes city transport almost free.
Tehran, then escape south
Tehran is a 9-million-person introduction: give it two nights for the Golestan Palace's mirrored halls, the shah-era excess of the National Jewels museum, and hiking-trail teahouses at Darband where the city dissolves into the Alborz mountains. Then head to the terminal. Iran's VIP buses are a backpacker miracle — huge reclining seats, snack box included, for $4–8 between major cities.
Kashan: courtyards and rosewater
Three hours south, Kashan is the desert's front porch, famous for 19th-century merchant houses whose plain mud walls hide courtyards of astonishing stucco and wind-catching towers. Several are now guesthouses; sleeping in one — floor mattresses around a fountain courtyard, breakfast of flatbread, honey and carrot jam — is the accommodation experience of the trip ($15–30). See the Tabatabaei and Borujerdi houses, sink into the steamy beauty of the Sultan Amir Ahmad bathhouse, and take a half-day taxi loop to Abyaneh, a red-clay mountain village, or the desert dunes of Maranjab.
Isfahan: half the world
The old boast — Esfahan nesf-e jahan, Isfahan is half the world — survives contact with reality. Naqsh-e Jahan Square is one of the largest on earth, edged by two of the most beautiful buildings anywhere: the Shah Mosque with its cavernous turquoise dome, and the smaller Sheikh Lotfollah, whose dome shifts from cream to pink as the sun moves. Entry fees run ~$4–6 each. Give Isfahan three nights: the Armenian quarter of Jolfa and its fresco-lined Vank Cathedral, tea in the bazaar's hidden courtyards, and evenings at Si-o-se-pol, the 33-arched bridge where locals gather to sing under the vaults — the acoustics turn strangers into choirs.
Yazd: the desert city
Five hours on, Yazd is a mud-brick maze that has barely changed shape in centuries — wind towers, covered lanes, rooftops made for sunset tea. It is the centre of Zoroastrianism: visit the Fire Temple, whose flame has reportedly burned for over 1,500 years, and the Towers of Silence on the city's edge at dusk. Rooftop cafés serve camel stew and pomegranate everything; hostels here ($10–20) have the best terraces in Iran. A day trip out to the caravanserai and abandoned mud town of Kharanaq with a sunset in the dunes rounds it off.
Shiraz and Persepolis
Finish in Shiraz, city of poets, gardens and nightingales. Go early to the Nasir-ol-Molk 'Pink Mosque', where dawn light through stained glass floods the prayer hall carpet in colour; pay respects at the tomb of Hafez alongside Iranians who queue to read his poems as oracles. The essential day trip is Persepolis (one hour; shared taxi ~$15 return, entry ~$5): the ceremonial capital Alexander burned, its bas-relief processions of tribute-bearers still crisp after 2,500 years. Standing before the Gate of All Nations at opening time, alone but for swallows, is the moment the whole route has been building toward. When to go: March–May or September–November; summer in Yazd is an oven, and Nowruz (late March) is joyous but books out weeks ahead.
