The Old Caoling Trail Circle-Line Bikeway is about 20km long. Ecological engineering methods are applied to build this hilly path that merges perfectly with the Pacific skylines. The trail leans against old rail tracks and therefore it has typical railway characteristics. The countryside scenery changes along the way. Along the trail are also Magang and Maoao fishery villages known for their unique history and culture.
