A mountain located in Busan, South Korea, named 'Jang'mountain

It is a mountain located in Haeundae-gu, Busan, Korea.
It is 634m above sea level and 9km on the road.
The round trip takes about 4 to 4 hours and 30 minutes, and it varies from person to person.
Because there is a military base near the summit, it is impossible to access certain areas, and there are also areas in the middle of the hiking trail that have mine warning signs that are not actually detected.
Of course, it's safe and well guarded, so it's not dangerous at all.
The silver grass field, which arrives about 3/4, is especially spectacular in autumn.
