Official Source Guide
GoSeoul is independent, but the route structure starts with official tourism sources. This page explains how official pages are used so travelers and ad reviewers can understand the editorial process.
VisitKorea is the first planning layer because it provides travel basics, transportation, accommodations, food, shopping, suggested itineraries, multilingual access, and themed browsing.
When a route is related to Korean dramas, K-pop, performances, or culture spaces, we look for official theme areas such as Hallyu, K-Performance, and HiKR Ground before using broader web context.
Regional tourism offices are used to verify local city identity, travel value, transport logic, and whether a fan-interest stop can become a full route.
Travelers should check official pages for current opening hours, transport changes, seasonal weather, accessibility, and visitor support such as the 1330 Korea Travel Helpline.
