Introduction

Between Ruifang Station and Shuangxi Station lie nine tunnels, giving rise to the well-known Taiwanese saying “passing through nine tunnels with merely a penny”.

Among these tunnels, four have bikeways built within. With a total length of 3.19 km, the Sandiaoling Eco-friendly Tunnel, which is the revival of abandoned Yilan Lane railway for over 30 years. What’s more, it is the first “rebar bikeway”in Taiwan, and the designer of it incorporated a pond design to illuminate the tunnel’s entrances, creating a stunning and mirror-like reflection that echoes with the verdant mountains of Sandiaoling.

With possibility, you might get a chance to encounter trains during the journey. Considering safety for two-way traffic between Sanguatsu tunnel and the wall-hanging bridge, cyclists are required to dismount and walk with their bikes through this pathway.
As the newest route in the low-carbon travel initiative of Route 2 Taiwan, the Sandiaoling Tunnel Bikeway and Sanguatsu Tunnel Bikeway connect the tourism routes of Mudan in Shuangxi and Sandiaoling in Ruifang district.

To mitigate traffic impacts caused by the limited space within the tunnels, visitors are required to apply for entry in advance via online platform (click here to visit). Along the route, interpretation boards highlight the features of this area, and visitors may also make reservations for tour guides through the reservation website.
