Iraq.

No country has a deeper claim on the human story. The first cuneiform tablets were pressed in Sumerian Uruk around 3,200 BCE. The wheel, irrigation agriculture, the 60-minute hour and the codified legal system all emerged in Mesopotamian cities whose ruins are still visible from a Baghdad day-trip. Babylon, an hour and a half south of the capital, was inscribed by UNESCO in 2019 after decades of campaigning; the Ishtar Gate (in Berlin) is gone but the Processional Way, the Lion of Babylon, and Saddam Hussein's controversial 1980s reconstructions are walkable. Ur, in Dhi Qar province, is where Abraham is traditionally said to have been born, the great ziggurat is one of the most photogenic ruins in the Middle East. Nineveh and the Mosul plains contain Assyrian sites severely damaged by ISIS but partially recoverable.

Islamic Iraq is just as layered. Najaf, 160 km south of Baghdad, holds the gold-domed Imam Ali Shrine, the spiritual heart of Twelver Shi'ism and a city built around the cleric, scholar and pilgrim economy. Karbala, an hour north, is where Imam Hussein was martyred in 680 CE; the Imam Hussein Shrine with its mirrored interior is the destination of the Arba'een pilgrimage forty days after Ashura, the world's largest annual gathering, over 20 million walkers, dwarfing the Hajj. Samarra, north of Baghdad, holds the spiral 9th-century Malwiya minaret and the Al-Askari Shrine sacred to Shia Muslims. Baghdad itself, wounded by decades of war and sanctions, still has the Mutanabbi Street book market on Fridays, the Iraq Museum (with the Warka Vase, Nimrud reliefs, and recovered Bactrian gold), and the riverside masgouf fish restaurants on Abu Nuwas Street that have somehow survived everything.

In the north, Iraqi Kurdistan offers a quietly different country. Erbil (Hewlêr) is built around a citadel mound that has been continuously inhabited for at least 6,000 years, possibly more. Sulaymaniyah is a university city with the Amna Suraka (Red Security) museum documenting the Anfal genocide. Lalish, in the hills above Duhok, is the holiest temple of the Yazidi faith. The Hamilton Road through the Zagros, the Halgurd-Sakran national park, and the alpine resort of Korek Mountain reframe Iraq as a country with its own walking-and-mountain idiom. None of this excuses the security context, repeated once in the practical section below, but five thousand years of urban civilisation deserve more than a single advisory headline.

Iraq's climate is sharply continental and brutally seasonal. The southern lowlands, Baghdad, Najaf, Karbala, Basra, the marshes, sit at 30–60 metres above sea level and experience some of the hottest summer temperatures recorded in the inhabited world. Baghdad routinely tops 45 °C in July; Basra, on the Gulf, has hit 53 °C with humidity. Winters are mild (10–18 °C daytime, 4–8 °C overnight) and brief. Rainfall is sparse, under 150 mm a year in Baghdad, mostly between November and March. The Kurdistan north is a different country climatically: Erbil sits at 420 m, Sulaymaniyah at 850 m, and the Zagros peaks behind Choman exceed 3,600 m. Winter brings real snow to the mountains (skiing exists, just); summer in Erbil still hits 42 °C but evenings cool, and the high valleys are mid-20s with cold nights.

This produces two distinct travel windows. For Federal Iraq, Babylon, Najaf, Karbala, Baghdad, the southern marshes, the workable months are late October to early April. November and March are sweet spots: 18–24 °C daytime, manageable nights, dust storms less frequent. December–February is the coolest window with crisp blue-sky days but cool evenings around the shrines. April starts to push 30 °C and by May the south is uncomfortable. June through September is brutal, 45–50 °C in Baghdad, 50+ °C in Basra, and most non-pilgrim travel pauses. For Iraqi Kurdistan, the season is much wider: April to early November is comfortable, with peak walking and mountain conditions in May, June, September and October. July–August is hot in Erbil city but pleasant at altitude (Halgurd-Sakran, Korek, Rawanduz gorge). Winter (December–February) sees real snow in the high Zagros, niche skiers visit Korek, and Erbil itself drops to 5–10 °C with occasional snow.

The two big cultural-religious dates dominate any Iraq calendar. Nowruz on 21 March is the Kurdish national festival, bonfires lit on hilltops, families dressed in coloured jli kurdi robes, processions in Akre and Sulaymaniyah, the Erbil citadel illuminated. It is by far the most photographed and joyful moment in the Iraqi year for Kurdistan-focused travellers. Arba'een falls forty days after Ashura on the Islamic lunar calendar, in 2026 the Arba'een walk peaks around 13 August, and millions of Shia pilgrims walk from Najaf to Karbala over several days. Visiting Karbala during Arba'een is a once-in-a-lifetime experience but logistics are extreme: hotels booked a year ahead, road closures, intense crowds, and security alert at maximum. Ramadan (in 2026 falls February–March) closes most restaurants in Federal Iraq during daylight hours. Eid al-Fitr and Eid al-Adha jam transport for several days each; Iraqi Republic Day on 14 July is observed but quiet.

The single most useful thing a 2026 traveller can do is understand that Iraq has two parallel immigration systems. The Federal Iraq e-visa (and visa-on-arrival at Baghdad, Najaf, Basra airports) was opened to roughly 36 nationalities, most of Western Europe, the US, Canada, Australia, New Zealand, plus several Asian countries, between 2021 and 2024 via the visa.gov.iq portal. It costs roughly USD 75–100 for a 60-day single-entry tourist visa, plus an arrival fee on the day. The federal visa is valid for the whole country including Kurdistan. The KRG meanwhile runs its own visa-on-arrival at Erbil (EBL) and Sulaymaniyah (ISU) airports, free or roughly USD 75 depending on nationality, valid 30 days, valid only for the Kurdistan Region, entering Federal Iraq from a KRG-only entry stamp requires either a separate federal visa or an extension at the Federal Immigration office in Baghdad.

The practical implication: if your trip is Kurdistan-only, fly into Erbil and use KRG visa-on-arrival, simpler, cheaper, no e-visa application. If your trip includes Baghdad, Babylon, Najaf, Karbala or the marshes, apply for the federal e-visa first; that visa is valid in Kurdistan too. Mixed itineraries (e.g. arrive Erbil, exit Baghdad) work either way but need the federal e-visa if you cross from KRG into Federal Iraq overland, the Kalak / Khazir checkpoint between Erbil and Mosul is the busiest crossing.

Operators and independent travel. Specialist operators running scheduled small-group tours of Federal Iraq include Untamed Borders, Hinterland Travel, Wild Frontiers, Lupine Travel, and a growing list of Iraqi ground operators in Baghdad and Najaf. Typical southern itineraries, Baghdad–Babylon–Najaf–Karbala–Ur–Basra–marshes, run 8–12 days at USD 2,200–3,800 plus international flights via Istanbul, Doha or Dubai. Kurdistan is the most-visited part of Iraq for independent travellers: scheduled flights into Erbil from Doha, Dubai, Istanbul, Vienna and Frankfurt; English-speaking taxis and hotels; Erbil–Sulaymaniyah–Duhok in 6–8 days fully self-driveable. Independent backpackers regularly attempt Federal Iraq with a hired driver-guide; this is technically possible and increasingly common but advisory-flagged.

Security context, second and final mention. Most Western governments, UK FCDO, US State Department, German Auswärtiges Amt, Australian DFAT, classify Federal Iraq at Level 4 do not travel, citing terrorism (residual ISKP/Islamic State remnants in rural Anbar and Nineveh), Iran-aligned militia activity, kidnapping risk for Western passport holders, unexploded ordnance off-piste, and occasional rocket attacks on US installations near Erbil and Baghdad. Kurdistan sits at Level 3 reconsider travel; the disputed border areas (Sinjar, Kirkuk fringe, the Iran/Turkey border zones) carry higher risk than the Erbil–Sulaymaniyah–Duhok core. Standard travel insurance often excludes Iraq, confirm with your provider, and consider specialist policies (High Risk Voyager, Battleface, Global Rescue) for medical evacuation. Operators monitor risk continuously and will adjust itineraries; that risk-management capacity is the main thing their fee buys.

Money, costs and practicalities. Iraqi dinar (IQD) at roughly 1,310 to the dollar; ATMs work in Erbil and Baghdad but are unreliable elsewhere, bring clean post-2013 USD bills for the bulk of any trip. Budget travellers in Kurdistan get by on USD 40–60 per day (hostel beds in Erbil, shared taxis, kebab dinners); mid-range USD 80–150. Federal Iraq runs roughly USD 50–80 per day independent or USD 200–400 per day on a guided tour including driver, guide, vehicle and hotels. Erbil hotels USD 60–150 mid-range, Baghdad USD 80–200, Najaf and Karbala USD 40–100. A masgouf (the iconic split, salt-rubbed, slow-grilled river carp) on Abu Nuwas Street runs USD 20–40 for two; a kebab plate USD 5–10; a glass of cardamom chai a few hundred dinars. Mobile data is cheap, Korek Telecom and Asiacell both run reliable 4G. Arabic dominates Federal Iraq, Sorani Kurdish in the south of Kurdistan and Kurmanji in Duhok; English is functional in Erbil hotels, government tourism offices, and most operator-led groups but absent in rural areas. Etiquette: long sleeves and trousers for men, headscarf and full sleeves/legs for women in Najaf and Karbala (women wearing a black abaya are conspicuously normal at the shrines); shoes off in homes and shrines; right hand for eating; no photography of military, government buildings or checkpoints; alcohol legal but discreet in Baghdad and freely available in Erbil.
