Karaj is Iran's fourth-largest city, sitting in the foothills of the Alborz mountains just west of Tehran. As the capital of Alborz province, it's a practical base for travellers heading into the mountains for skiing and hiking, or using the wider Tehran area as a gateway to the rest of Iran. There are no direct flights from the UK, so getting here always involves a connection, but with the right planning it's a straightforward journey.
Spring (April–May) and autumn (September–October) bring mild, dry weather and are popular with travellers exploring the region on foot. Winter turns cold with heavy snow in the mountains, drawing skiers to nearby resorts, while summer is hot and largely dry. Fares to Iran shift with these seasons and around the Iranian New Year (Nowruz, late March), so check the When to book chart above before settling on dates.
No airline currently flies non-stop between the UK and Iran, so flights to Karaj from the UK are booked via a connecting hub. Turkish Airlines (via Istanbul), Qatar Airways (via Doha) and Austrian Airlines (via Vienna) are the most established options, routing UK travellers into Tehran's Imam Khomeini International Airport before a short road transfer on to Karaj. All-in journey times typically run from around 10 to 14 hours depending on the connection, so it's worth comparing airlines using the price charts on this page.
Karaj makes a handy base for exploring the Alborz mountains as well as its own local sights.
Payam International Airport lies around 15km from central Karaj and mainly handles domestic and cargo traffic, so most UK travellers instead land at Tehran's Imam Khomeini International Airport and continue to Karaj by road, a transfer of roughly 45 minutes to an hour depending on traffic. Taxis and pre-booked private transfers are the most reliable way to complete the journey, since public transport links are limited.
UK nationals need a visa arranged in advance through an authorised agency, as Iran does not offer visa-on-arrival to British passport holders. The currency is the Iranian rial, and UK debit and credit cards do not work in Iran due to international sanctions, so bring enough cash in pounds or euros to exchange locally. Check current FCDO travel advice before booking, and make sure your travel insurance explicitly covers travel to Iran.
Your allowance to Karaj depends on the airline and the fare you book. The table below shows typical long-haul allowances so you know roughly what to expect — always confirm the exact limits with your airline before you fly.
