Overview
Indonesia's third-largest city, Medan is the gateway to North Sumatra and one of the best-value long-haul destinations for UK travellers this year. It's a lively, multicultural hub of colonial-era architecture, streetside satay stalls and mosques and temples standing side by side — but its real draw for most visitors is what lies beyond the city: Lake Toba, Bukit Lawang's orangutans and the jungles of Gunung Leuser National Park are all within easy reach of Medan's Kualanamu Airport, making the city the natural starting point for a Sumatra adventure.
Best time to fly to Medan
Medan has a tropical climate with warm temperatures year-round, so there's no bad time to go weather-wise. The driest, most comfortable months tend to fall between February and April and again around June to September, with October to January bringing the heaviest rainfall. Shoulder-season travel (outside Indonesian school holidays and the Eid period) generally means fewer crowds and better availability — check the When to book chart above for how fares are trending across the year.
Airlines and routes
There are no non-stop flights from the UK to Medan, so journeys involve at least one connection. The most common routings link London with Kualanamu International Airport via major Asian or Gulf hubs — think Singapore Airlines or Scoot through Singapore, Malaysia Airlines or AirAsia via Kuala Lumpur, Garuda Indonesia via Jakarta, or Gulf carriers such as Qatar Airways and Emirates connecting through Doha or Dubai. Depending on the routing and layover time, expect a total journey of around 16 to 20 hours from London. Regional carriers such as AirAsia also offer well-priced onward hops from Southeast Asian hubs.
Things to do in Medan
Medan rewards a day or two of exploring before heading further into Sumatra. Highlights include:
- Maimun Palace: The elegant former residence of the Sultan of Deli, blending Malay, European and Islamic design.
- Great Mosque of Medan (Masjid Raya Al Mashun): A striking early-1900s mosque with Moorish-influenced architecture, still active today.
- Tjong A Fie Mansion: A beautifully preserved merchant's home showing Medan's Chinese-Indonesian heritage.
- Lake Toba: The world's largest volcanic lake, a scenic few hours from Medan and well worth an overnight stay.
- Bukit Lawang: Gateway to Gunung Leuser National Park and one of the few places to see wild Sumatran orangutans.
At Kualanamu International Airport (KNO)
Kualanamu sits around 39km from central Medan. The Airport Rail Link is the quickest way into town, reaching Medan Railway Station in roughly 30–45 minutes. Metered taxis, ride-hailing apps and airport buses are also available if you'd rather go door to door, with journey times varying depending on traffic.
Top tips for finding cheap flights to Medan
- Book several months ahead where possible — long-haul routes with connections tend to offer better fares the earlier you commit, particularly outside Indonesian public holidays.
- Flying midweek (Tuesday to Thursday) is usually cheaper than weekend departures on the connecting legs.
- Stay flexible with dates and even nearby dates by a few days — use the price charts on this page to spot the cheapest days to fly.
- Compare connecting airlines and hubs rather than fixating on one carrier — routing via Singapore, Kuala Lumpur or Jakarta can produce very different fares for the same dates.
Travel essentials
UK passport holders need a visa to enter Indonesia; most travellers arrange a Visa on Arrival at Kualanamu Airport, valid for 30 days and extendable once, so check current requirements before you fly. The currency is the Indonesian Rupiah (IDR) — cards are widely accepted in hotels and city restaurants, but it's worth carrying cash (converted from GBP) for markets, transport and rural areas near Lake Toba or Bukit Lawang. No mandatory vaccinations are required for UK travellers arriving directly from the UK, though routine cover and antimalarials/insect protection are sensible depending on where you're heading in Sumatra — check with a travel health clinic and take out comprehensive travel insurance before departure.
