KR Pass — Korea Rail Pass (Unlimited KTX & All Lines)

Highlights

• Flexible day counts: 2-day (US$92), 3-day (US$131), 4-day (US$165), or 5-day (US$194) pass — pick any days you want within a 10-day window, no need for consecutive dates
• Unlimited rides on KTX, ITX-Saemaeul, and Mugunghwa-ho trains — one pass covers round trips between Seoul, Busan, Gyeongju, and other major cities
• Also covers scenic tourist trains like the O-train, V-train, and S-train, good for a deeper dive into central or south-coast rail routes
• Travelers with a foreign passport can buy this directly online — it’s not valid for Korean passport holders

Good to know

• The pass alone doesn’t let you board: you must reserve a seat separately on the official Korail website or app (passport details required). Skip this step and you may have no seat at all — book your seats as soon as you can after buying the pass.
• The name you enter when reserving must match your passport exactly — a misspelling can get you turned away or force an on-the-spot correction.
• During peak periods (holidays, weekends, school breaks), popular trains sell out fast — reserve your preferred times and seats right after purchase.
• Child tickets (ages 6–12) are roughly half the adult price; check the booking page for the exact cancellation terms.

Side trips this pass makes easy

Once you have a KR Pass, riding KTX from Busan to Gyeongju — or further — costs nothing extra. For route ideas, see our Gyeongju day tour comparison on the site. [internal link placeholder]
