Seoul to Busan by Bike

The route

The route is one line drawn diagonally across the country. It starts at the Ara West Sea Lock near Incheon, on the Yellow Sea, and follows the Ara Canal east to the Han River. It runs straight through Seoul on the riverside paths, then climbs gently up the South Han (Namhangang) to Chungju. There it leaves the water for the Saejae section, which crosses the Sobaek Mountains by two passes. On the far side it drops to the Nakdong River and follows it, long and patient, through Sangju, Gumi and Daegu to the estuary at Busan.

Most riders go north to south. You start where the canal meets the sea, buy your stamp passport at the first certification centre, and finish at the sea again in Busan.

What the riding is like

Mostly, it is the steady following of water. You ride embankment paths where the main sounds are your tyres and the river. The red certification booths come up every so often, like punctuation, and one watershed slowly hands over to the next. Through Seoul and the bigger towns the path runs through riverside parks, shared with walkers. Beyond them it is quieter, and some embankment stretches are a long way from the next village.

It is a route about rhythm and distance rather than drama, with one exception. The Saejae section crosses two passes in quick succession. Riding south, Sojoryeong comes first: a climb of about 140 metres over 2.3 kilometres, to 380 metres. Then comes Ihwaryeong, at 539 metres the longest and highest climb on Korea’s certification paths: about 310 metres of climbing over roughly 5 kilometres, averaging over 6%. On a loaded touring bike it is hard work but not technical, and the country around Mungyeong is some of the prettiest on the ride. The reward is a long descent to the Nakdong.

It is a route about rhythm and distance rather than drama, with one exception.

Older accounts give Ihwaryeong as 530 to 550 metres high with a climb of about 7 kilometres. Treat it as one substantial mountain day and plan it as your shortest day. The rest of the route is nowhere near as hard, but it is not dead flat either.

The stages

The route is made of four official bike paths, and the table splits the Han path into its Seoul and South Han parts. These are geographic stages, not days: the Nakdong alone is two or three days’ riding.

Section lengths from Korea by Bike’s route pages, read 1 October 2026. The Seoul figure is the 192 km Hangang path less its 132 km South Han part, and the Nakdong figure is the 389 km Nakdong path less the 70 km above Sangju. Both are our arithmetic; together the stages make about 633 km.

A five- to seven-day shape

One recent guide suggests six days at about 100 kilometres a day, seven or eight for first-timers, and four or five for fit riders. A common pattern is one day from Incheon through Seoul and one up the South Han to Chungju. The Saejae gets its own shorter day, and the Nakdong takes two or three. Stop in the towns rather than between them, because beds and food are there.

Planning the ride

The bike, and getting back

You can bring your own bike, but many visitors hire one. Several Seoul-based shops specialise in one-way hire for this route: they deliver a bike in the Seoul area and collect it in Busan, which solves the return. Riders have reported a drop-off fee of around US$100; we could not confirm a current figure, so ask when you book. Book ahead in spring and autumn.

The KTX from Busan to Seoul takes about two and a half hours. It accepts a bike only if it is a folded folding bike, or taken apart and packed in a dedicated bag. There is no roll-on space. Korail’s commuter trains generally take full-size bikes at weekends and on public holidays. Decide how you and the bike are getting back before you set off, not in Busan.

The stamp passport and the medal

Korea turns the ride into a stamp rally. You buy a small certification passport for ₩4,000 at a staffed certification centre; the Ara West Sea Lock, at the start, is the obvious one. Then you stamp it yourself in the red booths along the path. Finish the route and you can claim a certificate, and buy a medal. It is optional and a little kitsch, and most riders end up loving it.

Bring won in cash: riders report that foreign cards often fail at certification centres.

Beds, food and water

The towns along the route have cheap motels and pensions, and Seoul and Busan have proper hotels. Book ahead at weekends and in the autumn foliage season. Convenience stores are frequent enough to resupply on the move, but carry water and food into the quiet embankment stretches and over the Saejae passes. For maps, use Naver or Kakao rather than Google; our guide to staying connected in Korea covers data and apps.

When to ride

Spring, April to June, brings blossom and mild air. Autumn, September to November, is the classic window: cool, clear, and lit by the foliage the hills are famous for. Summer is hot and humid, with the jangma monsoon rains and the occasional typhoon. Winter is cold and can be icy on shaded riverside sections. Our guide to the best time to visit South Korea covers the seasons in more detail.

If the ride breaks down

The route runs close to the rail network, and towns such as Chungju, Gumi and Daegu have stations. If you run out of time or energy, you can leave by train and rejoin another day. The bike has to travel too: bagged on the KTX, or on a commuter train at the weekend. An e-bike cannot go on the train at all, so a hired e-bike has to go back through the hire company.

On the Saejae section, decide at Chungju or Suanbo whether you are fit for both passes that day, and stop for the night rather than start the climbs late. On the quiet Nakdong stretches, do not count on the next village for water. In an emergency, call 119 for an ambulance, or 112 for the police.
