Korea Hallasan

It is the highest mountain in Korea.
Hallasan is located on Jeju Island and is 1950m above sea level.
Hallasan is a dormant volcano and the crater of Hallasan is called Baengnokdam.
I climbed the mountain in mid-December, and there were hundreds of people on the summit at the time, so I had to stand in line for at least 30 minutes to take pictures at the monument.
So, my friend and I didn't stand in line and brought our cup noodles, but we poured lukewarm water to cool down, ate leisurely, and went downstairs.
