Before heading out to enjoy the autumn leaves, you can check the foliage status at Yumyeongsan using the Korea Meteorological Administration's WeatherNuri service. This page provides a list of mountain names and differentiates between pre-foliage, first foliage, and peak foliage. First, confirm the mountain you plan to visit, then read the photo dates. It's crucial to distinguish between the date you accessed the webpage and the date the photos were taken, as just because you opened the page today doesn't mean the photos were taken today.

First, Confirm the Mountain Name and Observation Location

By using the official link below, you can access the Yumyeongsan foliage status and view the list of observation locations. The list includes mountain names such as Seoraksan, Odaesan, Bukhansan, Chiaksan, and Gyeryongsan. It’s advisable to check the mountain name first, then look at the corresponding observation location for the photos.

  1. Open the Yumyeongsan foliage status page using the official link below.
  2. Find the mountain name you want to check in the observation location list and confirm it matches the displayed mountain.
  3. Read the photo shooting locations indicated under the selected mountain, such as proximity and overall observation locations.
  4. Compare the pre-foliage, first foliage, and peak foliage photos along with their respective shooting dates, then click to view the photos in detail.
💡 Editor's Practical Tip: Observe the Flow of Dates from Pre-Foliage to First Foliage to Peak Even for the same observation location, the shooting dates for pre-foliage, first foliage, and peak foliage photos can differ by several weeks. By comparing the shooting dates side by side, you can determine which stage the mountain is currently in, and the weather and temperature data displayed alongside the photos serve as useful references for understanding the foliage situation.

Reading the Stages and Dates of Photos Together

The screen for the confirmed Sobaeksan showed a distinction between the proximity observation location at the entrance of Birosa and the overall observation location at Samga Reservoir. The photo table includes the shooting date along with the weather and temperature, and there is also a detailed view option. Use these observation location labels to understand what point the photo is depicting. The confirmed Sobaeksan photos show that the pre-foliage was taken on 2026-09-17, the first foliage on 2026-10-15, and the peak on 2026-10-22.

To avoid mistaking old photos for today’s scenery, always check the shooting date displayed on the photos.
