Jangsan

This guide to Jangsan in Busan opens with a strand of barbed wire on the mountain's summit above one of Korea's wealthiest districts, where the Korean military still holds the highest ground off limits to hikers. It sets that fenced radar station against the fortunes built at the mountain's foot, in the towers and apartments of Haeundae-gu that have made headlines for decades. Below the fence line, the silver grass fields and the Jungbong observation deck are still open to anyone willing to climb.
