🏔️ Conquer Hallasan – The Most Magical Day Hike in Jeju (2025 Travel Guide)
If you’re visiting Jeju and want to do more than just beach-hopping and cafe-hopping, here’s your sign: hike Hallasan, Korea’s highest mountain at 1,947 meters (6,388 ft).
This dormant volcano in the heart of Jeju Island isn’t just about hiking—it’s about witnessing how nature transforms as you climb, from lush subtropical forests to alpine landscapes. In 2025, Hallasan is still one of the most underrated but rewarding experiences in Korea.
🌿 Why Hallasan Is Worth It
- UNESCO Natural Heritage Site – This place isn’t just pretty, it’s protected for its rare biodiversity.
- Volcano + Crater Views – On a clear day, you’ll see Baengnokdam, the dramatic crater lake at the summit.
- You Walk Through Seasons – Seriously. From green jungle vibes to rocky ridgelines, in one day.
Seasonal Highlights:
| Season | What You’ll See |
|---|---|
| Spring | Fields of pink azaleas 🌸 |
| Summer | Misty green ridges ☁️ |
| Autumn | Fiery fall foliage 🍁 |
| Winter | Dreamy snow-covered trails ❄️ |
NEW in 2025: Hallasan is testing a mobile reservation system for some peak seasons (especially October to November), so check the KNPS Website before you go.
