Venturing into the provinces has long meant confronting a fragmented, deeply analog intercity bus network whose digital reservation platforms remain largely inaccessible to holders of foreign passports and overseas credit cards.

The Ministry of Culture, Sports and Tourism, along with the Korea Tourism Organization, announced a coordinated monthlong campaign on Monday to dismantle these transit barriers.

Partnering with international travel booking platform Klook and fintech firm Hanpass, the government will subsidize tickets and provide digital perks from June 15 to July 14 to encourage independent travelers to explore the country's rural interior.
