In 1935, when setting up a national park, the Japanese built a new trail from Yuanfeng to Kalapao. After the work was finished, for a time this brand new Hohuan Trail became a tremendously popular hiking route, and enabled many people to fulfil their life's dream of walking along mighty cliffs and gazing out over the Central Range.
一九三五年日人為了成立國立公園，因而將鳶峰到卡拉寶的合歡聯絡路段修築完整，完工之後，全新的合歡越道路成為當時盛極一時的健行路線，並且讓許多人完成了橫越大斷崖、展望中央山脈的一生夢想。
