Sandiaoling Eco-friendly Tunnel Introduction
From Ruifang Station to Shuangxi Station, there are a total of 9 old tunnels, leading to the Taiwanese proverb "One dime drills nine holes." Among them, 4 of the old tunnels have been converted into bicycle paths. The San Diao Ling Eco-Friendly Tunnel, which has been reopened after 30 years of abandonment of the old Yilan Line railway tunnel, is 3.19 kilometers long and is the first "reinforced concrete bicycle path" in Taiwan. The designer utilized a water pool design to create a transition from darkness to light at the tunnel entrance, reflecting the stunning scenery of the verdant San Diao Ling mountains. There is also a chance to encounter trains along the way. For safety reasons, bicycles must be walked through from the San Guazi Tunnel to the Cliff-Hanging Bridge for two-way traffic. The San Diao Ling Tunnel and San Guazi Tunnel bicycle paths connect the tourist routes of Shuangxi Mudan and Ruifang San Diao Ling, making it the latest route in the low-carbon tourism initiative of the Youth Mountain-Sea Line. To reduce traffic impact and due to limited space within the tunnel, visitors must apply for entry online in advance (click here to proceed). Along the route, there are explanation boards explaining the features of the area, and guided tour services are available on-site; the public can apply for tours through the reservation website.
