The Zhuilu Old Road was part of the old Cross- Hehuan Mt. Road during the Japanese Occupation. Along the trail， there are many tribal sites and monuments of high historical and cultural values. As a result， the trail has been designated a "Historic Preservation Area". In 2008 after maintenance， the trail was reopened to the public. Hiking permit is required in advance.By visiting the trail， you will be able to experience the abundant natural scenery， and understand the value of the rare native plants. You can also overlook the Liwu Canyon， and have a superior vantage point of the entire area. Walking on the trail is often described as similar to walking in the clouds.Some sections of the trail follow the Zhuilu Precipice， where the trail is extremely narrow， with Liwu River 500 meters below. These sections are very challenging to hike. Fences and chains are installed to ensure the safety. Before entering the trail， visitors should observe the relevant regulations and be sure to protect the delicate environment.
