The Korea Bike Passport: How the Red Stamp Booths Work

Where to Buy the Passport

You can pick up the official Four Rivers Bike Passport (수첩 / Sucheop) for about 4,500 KRW (~$3.50 USD) at major starting hubs:

Incheon Ara West Sea Lock (the official start point near the coast)

Ttukseom Park Certification Center in Seoul (right along the river path)

How the Stamp System Works

The Booths: Inside each red booth, you’ll find a unique rubber stamp representing that river landmark. You stamp your physical passport at each station along the ~530 km route.

The Dry Ink Pad Issue: Sometimes the ink pads inside the remote booths are dried out. Many cyclists bring a small, cheap ink pad from a 100-yen/1,000-won shop just in case.

Digital Backup: Download the "Bike Korea" (사이버검증) app. If a booth is missing or broken, you can take a GPS photo at the booth location to prove you were there and register the stamp digitally.

Getting Certified in Busan

Once you reach the end at the Nakdonggang Estuary Bank in Busan, head to the certification office. They review your passport, sign off on your ride, and you can buy an official completion medal and certificate to pack home in your pannier.
