Quick answer: The Korea Tourism Organization and the Korea National Arboretum released the 2026 Autumn Leaves Map on 8 October, listing 36 destinations. The Seoul area and Gangwon peak in late October; Gyeongsang and Jeolla from early to mid-November. Explera DMC Korea builds north-to-south group days around it, with a back-up stop for each.
What was released
- The map. The KTO and the Korea National Arboretum published the official 2026 Autumn Leaves Map on 8 October, with 36 natural and cultural destinations.
- The method. Forecasts use real-time observations from the Arboretum's Plant Phenology Project, with field data from 829 citizen scientists.
- The timing. The north, including the Seoul area and Gangwon, peaks in late October. Gyeongsang and Jeolla peak from early to mid-November.
- Places named. They include Incheon Grand Park, Goseokjeong in Cheorwon, Mungwang Reservoir in Goesan, Damyang's Metasequoia Road and Ttarabi Oreum on Jeju.
Using it to time group days
- Go north first. For a late-October arrival, put the Seoul area and Gangwon early in the programme.
- Move south later. A November group can follow the colour into Gyeongsang and Jeolla.
- Match the place. Put the lake and avenue stops, such as a reservoir or a tree-lined road, on the days the map says are strongest.
- Read it close to travel. A forecast moves with the weather, so we re-read it a week before arrival and again on the ground.
Why a back-up matters
- Colour is not guaranteed. Heat, rain and wind can bring the peak forward or put it back.
- Keep a second stop. Each foliage day has a palace, temple or museum option close by.
- Allow for crowds. Peak weeks are busy at the popular spots, so we set early starts and an alternative route.
- Say it in the proposal. We write "peak expected" with the source and date, not "guaranteed".
