The 8.5-kilometer Caoling Historic Trail is a highly popular hiking path in the Northeast Coast. Located between Yuanwangkeng of New Taipei City and Dali of Yilan, it was a major road for people to travel between Taipei and Yilan in the old days. It is also the only remaining section of the Danlan Old Trail.
Along the trail, lush green broad-leaved and coniferous forests, as well as iconic subtropical-rainforest mangrove trees, can be found. Cultural heritage such as Diesima Bridge, Xianji Rock and third-grade national treasure “Xiong Zhen Man Yan” writing and “tiger inscription” can also be appreciated. At the trail’s highest point, a sea of silver grass seem can be seen swinging in the winds in autumn time, as if they were ocean waves. The scenery along the trail is pleasant, making it a highly enjoyable hiking path with both natural and cultural charm.
