Where does the Cross-Country bike route run?
The Cross-Country route runs from the Ara West Sea Lock in Incheon to the Nakdonggang Estuary Bank in Busan, about 633 km. It links the Ara, Han, Namhangang, Saejae and Nakdonggang paths, mostly flat along rivers, with the Ihwaryeong and Sojoryeong passes on the Saejae section as the toughest climbs.

How do I use the bike-route certification centers?
At unmanned certification centers shaped like red phone booths placed at the start, midpoints and end of each route, stamp your bike-route passport. In case the booth's stamp is missing, it helps to take a photo of yourself with the certification section in the background.

The Han River path (Seoul section) and the Ara path are flat with good access, suiting beginners. For a day course the Bukhangang path is popular, and for a multi-day intro the relatively gentle Geumgang path is a favorite.
How many days does the Cross-Country take?
It depends on fitness and pace, but skilled riders covering 100-150 km a day take 4-5 days, while a relaxed 70-90 km a day with sightseeing usually takes 6-8 days. Allow extra time for the Saejae pass section.
