This is Taiwan's only volcanic mountain chain. In those days there was no national park, nor was mountaineering very popular. Most visitors stuck to the area around what is now the Yangmingshan National Park. For those who wanted to climb Tatun, there was but a narrow stone pathway, and you needed a guide to find even that.
這個是台灣本島唯一的火山山群，當時國家公園尚未成立，登山風氣也尚未蔚然成風，遊客多只在今日陽明山公園一帶活動，要登大屯主峰也只有一條石階步道，甚至沒有嚮導就摸不到僅有的小徑。
