1. What is the 'Snow Flower' (Nunkkot)?

In Korean, "Nunkkot" (눈꽃) literally translates to "Snow Flower." However, it doesn't refer to a plant, but rather a breathtaking natural phenomenon.

The mesmerizing 'Snow Flowers' blooming on the branches.

It refers to hoarfrost or snow that freezes onto tree branches, creating the illusion of white coral or crystal flowers blooming in the dead of winter. This scenery is often found in high-altitude areas like the Taebaek Mountain Range, which is the backbone of the Korean peninsula.

The "Snow Flower Train" is a special seasonal tourism train operated by KORAIL (Korea Railroad Corporation) designed specifically to take travelers through these spectacular, inaccessible winter landscapes.

2. The Most Popular Train Routes

While there are several winter routes, the most famous journey leads to Mt. Taebaeksan and the snowy highlands of Gangwon-do Province.

Here are the two main types of trains you should look for:

• The V-Train (Baekdudaegan Mountain Range Canyon Train): This train features open windows (in parts) and a retro design, moving slowly through deep valleys and cliffs covered in snow. It is often called the "Santa Train" during winter.
• The O-Train (Central Inland Circle Train): A comfortable loop train that connects major winter destinations like Jecheon, Taebaek, and Yeongju.

👉 Pro Tip: Many travelers combine the train ride with a visit to the Taebaeksan Mountain Snow Festival, usually held in late January.

3. Essential Booking Tips & Season

If you are planning to experience this magical journey, timing is everything.

• Best Time to Visit: Mid-January to Early February is the peak season for the heaviest snowfall and the best "Snow Flowers."
• How to Book: Tickets can be purchased via the LetsKorail website or the 'Korail Talk' app. These tickets sell out extremely fast, especially for weekends.
