KTO lists a digital-map app stamp tour by the Chungnam Culture and Tourism Foundation from September 7 to November 15, 2026. Travellers download the Chungnam electronic-map app and join its stamp activity to qualify for prizes. This uses an app and differs from the separate paper-sticker challenge marketed under Chungnam Travel Festa. The listing does not specify prize types, numbers or required stamp thresholds; call 041-630-2963.
