Cycling in Seoul: ride the river, take the metro

Is cycling in Seoul for you?

What you want the bike for changes the answer. Strong means it works for most visitors; Conditional means it works if you plan for the catch; Limited means a narrow use works, but the bike is not a sound way to explore. The verdicts are ours, drawn from the sources at the foot of the page.

What cycling is like

The river

The Han crosses Seoul from west to east, and a bike path runs along both banks through a chain of riverside parks. It is flat, smooth and kept apart from cars, with toilets, convenience stores and hire points along the way. It is also the city’s park, so you share it. In 2024 the city said only 40.2 of the 78 kilometres of Han path were physically separated from walkers. It had promised full separation for 2023, then 2025, and a council audit in November 2025 said the work could slip to 2027 or later.

So expect walkers, runners and families, and at weekends fast groups of road riders. The 20 km/h signs are advice, not law, and there are no fines. Recorded bike accidents in the Han parks rose from 65 in 2019 to about 116 in 2023, by the city’s figures as two newspapers reported them. Most were riders falling or hitting each other; eight were bikes hitting walkers.

The streets

Off the river, the evidence points one way, and it is why we cannot recommend the streets as a way to see Seoul by bike. At the end of 2025 the city counted 1,380.93 kilometres of what it calls bike road. That figure includes every type. Only 14% was bike-only and separated from both cars and walkers. Two-thirds was shared with pedestrians, usually a strip of pavement, and a quarter of the whole had nothing at all to separate the two.

Riders describe lanes that end at a junction without saying whether to join the pavement or the road. In February 2025 the city’s own auditors found bike lanes through bus stops without the warning markings its guidelines require. On a Korean cycling forum in May 2024, one thread was titled, in translation, “riding on city roads is putting your life on the line”, and residents named trucks, taxis and buses. Few people ride as everyday transport: about 2% of commutes and school trips in 2023, by the Seoul Institute’s count. So drivers do not expect you.

We found no crash rate per trip or per kilometre for Seoul, so we cannot put a number on the risk. We can say that nothing we found lets us call the streets safe, and a great deal points the other way.

Hills, heat and the seasons

Seoul is ringed by mountains, and some neighbourhoods climb hard: one visitor reported sustained gradients of 12 to 15%. The river paths stay flat, apart from ramps to the bridges and the Amsa pass in the east. Summer is hot and humid, so riders go early or after 5 pm, and one warns of insects by the water on summer evenings. Spring is the favourite season and the busiest; autumn is quieter.

Weather closes paths. Heavy rain shuts the stream paths, and in August 2025 all 29 of Seoul’s streams were closed after Jungnangcheon overflowed. Most riverside hire shops close from November to February. A study of public-bike use found that fine dust kept people off bikes, most of all in winter, so check the air-quality forecast before a long ride.

Where cycling works

Seoul offers five kinds of riding, and the line between them matters more than any single route. The table after them sets six rides side by side.

The central Han parks

Yeouido, Banpo and Ttukseom are the easiest parks to reach, with the most hire bikes and the best facilities. They are also the most crowded, and riders describe the stretch from Mapo to Banpo as the busiest on the river. Banpo is the place for a night ride, with its bridge fountain from April to October, but go on a weekday. The low Jamsugyo bridge beside it closes to cars from 26 October 2026; bikes and walkers can still cross, but it shuts to them too from May to August 2027.

The quieter ends

Ride west and the parks open out. Gangseo, on the south bank, is a wetland park of reed beds and willow woods with a bird-viewing deck, and one guide found its paths empty. Nanji, across the river, is quiet for the same reason: it is hard to reach without a car. To the east, the stretch from Jamsil to Gwangnaru is ridden mostly by regulars rather than hire bikes, and Gwangnaru has a bicycle park built for children to practise on. “Quieter” is our judgement from guides and riders; nobody counts riders by stretch.

The stream paths

Paths follow the Han’s tributaries into the city, and in spring they are its loveliest rides. Anyangcheon, in the south-west, is known for cherry blossom. Jungnangcheon, in the north-east, has clear water and spring flowers. Bulgwangcheon runs under a tunnel of cherry trees from Eungam to Mangwon, near the market and a west-facing park for sunset. From the centre, a 5.94 km path separated from traffic runs along Cheonggyecheon-ro towards Jungnangcheon, and a short link opened in 2024 joins the streams to the Han.

Bridges

Crossing the river is the awkward part. Only some bridges take bikes, the walkways on others are narrow, and map apps can send you over a bridge you cannot ride. The Haengju and Jamsu bridges have bike lanes fenced off from walkers. Check a crossing before you plan a loop around it.

Central streets and pavement lanes

This is where we would stop riding. The marked lanes in the centre are mostly pavement or paint, and they do not join up.

Six rides compared

Making cycling work

Getting a bike

Ttareungyi, Seoul’s public bike, has about 45,000 bikes at about 2,800 docks. A day pass costs ₩1,000 for rides of up to an hour, ₩2,000 for two hours and ₩3,000 for three. Within the day you can dock and take another bike at no extra cost, and every five minutes over the limit costs ₩200. Riders must be 13 or older. The bikes are pedal-only, and they come without helmets. Seoul’s short-term transport passes for visitors do not include them.

If it fails, the riverside hire shops are the simple answer. Seoul’s Hangang Parks office lists 12 along the river, charging ₩3,300 an hour for a bike and ₩6,600 for a tandem, with child-seat and family bikes too. You pay at a kiosk with a phone number. Most open from about 10 or 11 am to 8 or 9 pm from March to October, and most close from November to February.

Public bikes are not spread evenly. On visits in autumn 2024, reported in February 2025, the city’s auditors found docks near Yeouido Station at 250 to 400% of capacity. Nearby docks stood empty, so you may have to walk to the next dock to find a bike or to return one.

Bikes on the subway, the river bus and trains

Folded bikes go on the Seoul subway at any time. Full-size bikes go on Lines 1 to 8 at weekends and on public holidays, in the first or last car only. Line 7 also takes them on weekdays from 10 am to 4 pm. That began as a trial in 2020 and was still reported in force in September 2025, so check before you rely on it. Line 9 takes folded bikes only. The Han River bus carries about 20 bikes on each boat.

The airport railway has carried no full-size bikes since 5 January 2026, which matters if you are flying in to ride Seoul to Busan. Since 1 July 2026, electric bikes and e-scooters have been barred from the Seoul subway and from every Korail train, the commuter lines included.

E-bikes and e-scooters

Seoul’s public bikes have no electric version; private firms rent e-bikes instead. In law, a pedal-assist bike that cuts out at 25 km/h and weighs under 30 kg counts as a bicycle. Throttle bikes and e-scooters do not. They need a licence covering mopeds, the rider must be 16 or older, and riding without a helmet costs ₩20,000. We could not find whether an International Driving Permit counts, so assume it does not. Since 30 September 2026, e-scooters have been banned on five streets, including Hongdae’s Red Road.

Finding your way

Google Maps still gives no walking or driving directions in Korea, and none for bikes. Kakao Map gives cycling directions, including a route that avoids hills and stairs, and has an English interface. Naver Map also has a bicycle mode. The city’s Smart Seoul Map shows the official bike routes, pumps and repair stands, in Korean only.

Parking and repairs

Return a public bike to a dock. A bike out for more than four hours is treated as lost or stolen. The city listed free self-repair stands, with pumps and tools, outside five stations in 2020, including Yeouinaru Exit 1 and Olympic Park Exit 3.

The rules you must obey

These are the laws that matter to a visiting rider. All seven are national law, and none is special to Seoul.

From the Road Traffic Act as explained by Incheon city and Korean law firms, and the police rules for e-scooters, checked 13 October 2026. The text of the act would not open for us, and we found the lights rule only in secondary reports. Can I cycle in South Korea? covers the national rules in full.

In practice: carry lights, keep off the pavement unless it is marked for bikes, and walk the crossings. Seoul’s public bikes come without helmets, so bring your own if you want one. The 20 km/h on the Han signs is advice, but keep to it: most crashes there are riders falling or hitting each other.

Risk, recovery and the better alternative

When the path runs out

The usual failure is leaving the river and finding yourself on a pavement lane that stops, or on a road with buses. Decide before you leave the river where you will stop riding. Return or lock the bike at the last dock by the river, and walk or take the metro from there.

Crowds and speed

On a busy weekend afternoon, slow to walking pace through the park entrances, where children cross the path. Events close things too: on fireworks weekend in 2025 the city suspended public bikes around Yeouido from the evening before to the morning after.

After dark, and in bad weather

Riders warn that walkers on the river paths at night carry no lights and appear late, so ride slower and use your own lights. In summer heat, ride early or late and carry water. If heavy rain is forecast, expect the stream paths to close.

If something goes wrong

Call 119 for an ambulance and 112 for the police. The Korea Tourism Organization’s 1330 line helps travellers in English, and Seoul’s 120 Dasan line interprets for public-bike problems.

If cycling is not for you

You lose less than you might think. Walk a riverside park in the evening, take the Han River bus between Yeouido and Jamsil, or take the metro to Banpo for the bridge fountain. The river is the experience; the bike is only one way to have it.
