Hard-to-book Korea, explained in plain English — Hallasan summit slots, national park shelters, forest cabins and KTX tickets, with the exact opening dates and times in Korea time.
Most of these booking systems were built for Korean residents and change their rules often. We read the official notices in Korean, check every date against the source, and show when each guide was last checked. How we check facts.
