About the lengthNational cycling portal (MOTC) route 22195080001000, 'Dezikou River Bikeway': 11.50 km Yilan County gives about 9.5 km for the Dezikou system (the river bikeway, the Dezikou loop and the Linmei loop) and says the river stretch from Provincial Highway 9 to the Zhu'an river mouth is the part built so far. The portal's drawn lines (a long line out toward the coast and back, plus a short link) measure about 9.4 km. Neither source explains the 11.50 km figure.

Why these labels

Traffic and path type: The portal classes every drawn stretch as bike-only path. Yilan County's 2024 notice closes the right-bank embankment top of the Dezikou River in Jiaoxi to cars and scooters as a 'pedestrian and bicycle path' area, so expect walkers and birdwatchers. The start at Dezikou Bridge is on Provincial Highway 9, a main road, and the walk or ride in from Jiaoxi is on town roads.

Families: The embankment path is closed to cars and scooters and suits families, but the start sits on Provincial Highway 9 and no toilets or water are listed on the route.

Yilan County describes the Dezikou River Bikeway as running between large areas of fish ponds and wet farmland, where flocks of migratory birds feed in autumn and winter.

The built section runs from Provincial Highway 9 to the Zhu'an river mouth. At Zhu'an Bridge it meets the Yilan coastal bikeway, which the county says runs about 13.5 km south from Zhu'an Bridge to the Yilan River mouth, so the two can be linked into a longer ride.

The national cycling portal classes the whole line as bike-only path, and the county closes the right-bank embankment top to cars and scooters.

Who it suits

Families and easy riders staying in Jiaoxi, and birdwatchers in autumn and winter. Bring your own bike or plan a rental elsewhere: none was verified nearby.

The route

A ride plan, in order

  1. Join at the south side of Dezikou Bridge on Provincial Highway 9.
  2. Ride downstream (east) between fish ponds and farmland toward the coast.
  3. At Zhu'an Bridge, turn back, or join the Yilan coastal bikeway south toward Zhuangwei.

Getting there without a car

  • Per the portal: from TRA Jiaoxi Station walk about 650 m northwest along Wenquan Road to the Tangweigou bus stop, take bus 1766 toward Nanfangao (Nanning Market) to the Fangetian stop, then go about 160 m north along Provincial Highway 9 to the river. The bikeway entrance is on the south side of Dezikou Bridge.
  • The portal's station markers for this route are Jiaoxi and Sicheng. The street route by bike from either station is not described officially.

Bringing your own bike: TRA: a bike fully packed in a proper bike bag (no plastic or cloth bags; at most 150 cm long, and length plus width plus height at most 220 cm) can go on any train class; TRA may suspend this on long holidays. Unbagged bikes need a bike ticket on trains with bike capacity, between stations on TRA's list. Jiaoxi Station is on that list. Sicheng is not on the list. Whether bus 1766 carries bikes was not verified.

Renting a bike

No rental was verified near the route. YouBike does not operate in Yilan County.

Confirm hours, rates and availability directly with the provider. Cycle.tw does not take bookings.

Toilets, water and food

The portal lists no supply points on the line itself. Its nearest listed points are in Jiaoxi and Toucheng. Toilets, water and shade on the route were not confirmed.

Safety and conditions

  • The start is beside Provincial Highway 9. Cross and join with care, and keep children close there.
  • Walkers and birdwatchers use the embankment. Ride slowly and pass with a bell or a call.
  • Open to wind and sun; carry water.
  • Wear a properly fitted helmet.
  • Check the Central Weather Administration forecast before you go. Heavy rain, typhoons and earthquakes close paths, river parks and roads, sometimes for weeks.
  • Wear a properly fitted bike helmet, whatever the law says for your bike.

When to go

Autumn and winter for migratory birds (Yilan County).
