Landing to first stamp: Day 0 and Day 1

Read this before you land

Incheon Airport sits on an island, and for years the only way off it with a bike was a taxi — both original bridges ban bicycles. In January 2026 two things changed at once, in opposite directions: the AREX airport train now refuses full-size bikes entirely (any day of the week — only a folding bike, folded, or a bike packed in a bag within carry limits gets on), and the new Cheongna Sky Bridge (청라하늘대교) opened with a bike lane — the first bridge ever that lets you ride off the island. Plan around these two facts and Day 0 gets easy.

One more thing: don't unbox and assemble the bike inside the terminal — assembled bikes aren't welcome in the halls. Do it at your motel, or outside the terminal if you're riding out.

Our advice: make it Day 0, not Day 1

You've been folded into a plane seat for ten hours and your body thinks it's 3 a.m. Don't bolt a 70 km ride onto that. Land, grab an eSIM and cash from the ATM (you'll need ₩4,000 in cash for tomorrow's passport — the airport does NOT sell it), then move the still-boxed bike by van taxi (kiosks at both terminals) to a motel near the start — the Cheongna/Geomam area works well — or into Seoul if you want a city evening. Assemble the bike in your room, spin around the block, eat your first samgyeopsal, sleep like a rock. Tomorrow you start fresh, and the whole 633 km will thank you for it.

Feeling strong? The ride-out option

Landed at dawn with energy to burn? Since 2026 you can actually ride out: assemble outside the terminal, cross Yeongjong Island, take the Cheongna Sky Bridge bike lane to the mainland, then follow the Ara canal west to the start gate — roughly 25 km before your odometer officially starts. It's a genuine option now, but be honest with yourself: jet lag plus 25 km plus the real Day 1 is a big first bite. When in doubt, sleep first.

Day 1, 09:00 — Ara West Sea Lock: the ritual begins

The certification center opens at nine. Inside: ₩4,000 in cash, your travel passport for the ID check, and the little book that will run your life for the next week is yours. Walk to the red booth. Press the first stamp. That soft 'clunk' is the sound of the next 632 kilometers starting.

10:00 — the Ara Waterway warm-up

21 dead-flat kilometers of canal path to shake out the flight. Planes drift overhead into Gimpo, anglers nod as you pass, and the blue line — the one that ends in Busan — rolls out under your front wheel for the first time. Second stamp at the Hangang Lock, and suddenly you're on the Han River with Seoul's skyline stacking up downstream.

14:00 — Seoul slides past

This is the strangest part of day one: crossing a 10-million-person capital without meeting a single traffic light that matters. Riverside parks, tents, couples on rental bikes, someone practicing the saxophone under a bridge. Stamp at Yeouido. Snack at a convenience store with a river view. Keep east.

18:30 — first sunset, first motel

Most riders sleep around Paldang or Namyangju, ~70 km in. Find a motel on Naver Map (no booking needed), roll the bike into the room — normal here — and eat at whatever's glowing next door. Passport on the nightstand: three stamps already. Tomorrow the city noise disappears and the river gets quiet. That's when the trip really begins.
