Wuling Hehuanshan Cycling｜Taiwan's Highest Road, 3,275m
Wuling, at 3,275 meters, is the highest point on Taiwan's road network and a bucket-list climb for cyclists worldwide. The west route begins around 450 meters in Puli, Nantou; the east route starts near sea level on the Pacific coast of Hualien and follows the official Taiwan KOM Challenge course. Both finish above 3,000 meters. This guide covers the routes, climbing difficulty, altitude precautions, and road closures, drawing on official and semi-official sources.
Where Wuling Is, and the Cycling Challenge
Wuling stands at 3,275 meters on Provincial Highway 14A around the 31.5 km mark, at the western edge of Taroko National Park, in Ren-ai Township, Nantou County. It is the highest point on Taiwan's road network, and both the Tourism Administration and the Directorate General of Highways list it as such.
Wuling is the shared finish of two classic climbing routes and the official finish of the Taiwan KOM Challenge. The race, founded in 2012, brought Wuling to the attention of the international cycling scene, and many overseas riders planning a Taiwan trip build their itinerary around the climb.
Climbing from the West (Puli) or from the East (the Hualien KOM Route)
The west route starts in Puli, Nantou, following Highway 14 through Wushe and Cingjing Farm, then Highway 14A through Cuifeng and Kunyang up to Wuling. The traffic-control zone published by the Directorate General of Highways for cycling events spans Highway 14 km 57 to km 80 and Highway 14A km 0 to km 31.35, about 54 km in total. Cycling media measurements put the distance at roughly 52 to 55 km with total elevation gain around 2,750 to 2,900 meters. The spread comes from different starting points and GPS methods, and none of these figures is an official survey from the Highway Bureau.
The east route starts at Qixingtan on the Pacific coast of Hualien, following the Suhua Highway (Highway 9) and the Central Cross-Island Highway (Highway 8) through Taroko Gorge, Tianxiang, and Dayuling, then Highway 14A up to Wuling. The organizer, the Chinese Taipei Cyclists Association, lists the total distance as 105 km with a finish elevation of 3,275 meters, and this is the official course of the Taiwan KOM Challenge. Cycling media commonly cite a total elevation gain around 3,400 meters, but neither the organizer nor the Highway Bureau has published an official elevation survey. If you see a more precise or very different number elsewhere, treat it with caution.
Both routes demand over 3,000 meters of net climbing in a single day, with almost no long descents to recover on, which is why Wuling is often seen as the top of Taiwan's cycling challenges.
Reading the Gradient Numbers and Preparing Your Fitness
Cycling media and sports reporting commonly point to the Kunyang slope (nicknamed "Devil's Climb" among riders) and the final 2 km before Wuling (nicknamed "Heaven's Road") as the steepest sections on the west route, averaging roughly 7% to 8.3%. On the east route, the final 10 km from Dayuling (about 2,565 m) to Wuling is the toughest stretch, with a maximum gradient of 27.3% cited across multiple reports (some English sources say 27%). These figures come from cycling media and race coverage citing each other, and there is no official survey from the Highway Bureau or the race organizer confirming the exact number. Take it as a rough sign that a section is steep, not as a spec sheet you can check meter by meter.
Both routes are long, sustained climbs with few flat sections to recover your heart rate. Before you go, make sure you can hold a steady cadence through 3+ hours of continuous climbing, pack enough food, water, and cold-weather gear, and know your exit plan if you run out of gas. Support points along the way are limited, so plan conservatively.
What Official Health Guidance on Altitude and Weather Means for Cyclists
Wuling takes riders above 3,000 meters over a short distance, so altitude sickness is a real risk to take seriously. Guidance from the Centers for Disease Control of Taiwan and the Yushan National Park Headquarters (under the National Park Agency) recommends avoiding rapid altitude gain to let the body adjust. If your schedule allows, spend 1 to 2 days at 2,000 to 3,000 meters first, and once above 2,750 meters, keep your daily sleeping-altitude gain under 500 meters. This guidance was written for hikers, but the principle of climbing slowly and giving the body time to adjust applies just as well to cycling.
Official guidance also recommends that higher-risk individuals (based on personal assessment) see a travel medicine clinic before departure, avoid strenuous exercise and alcohol in the first 24 hours at altitude, and keep hydrating. Temperatures around Wuling swing widely between day and night and with the weather. Even in summer, the summit can be far colder than the lowlands, so pack enough warm, windproof layers. If you get a headache, nausea, or dizziness, slow down immediately and consider descending.
Road Closures and the Latest Official Notice to Check
Roads around Wuling are subject to seasonal and weather-driven traffic control, and the rules shift month to month with weather and construction progress. What follows are examples of notices found at the time of research. Before you go, check the Directorate General of Highways or the Taroko National Park Headquarters website for the announcement of the current month, and never treat the hours in an old notice as a fixed rule.
During winter icing, Highway 14A between km 18 (Cuifeng) and km 41.5 (Dayuling), which lies above 3,000 meters, may see a preemptive closure (exit-only) from the Central Region Maintenance Engineering Office when snow or ice risk is high. The narrow, winding Wuling to Songxue Lodge stretch is slippery and may be closed in both directions, reopening the next day depending on conditions, sometimes limited to vehicles with snow chains. Every May and June, during the rhododendron season on Hehuanshan, high-occupancy traffic control applies on weekends and holidays from 6 to 11 a.m. on Highway 14A between km 29 (Kunyang) and km 33.2 (Shimen Mountain).
If you take the east route through the eastern section of the Central Cross-Island Highway, access runs on a time-slot system, and the two halves follow different rules. Under the September 2026 notice, Highway 8 between km 114.6 (Guanyuan) and km 167.1 (Tianxiang) is open to two-way traffic from 06:30 to 16:30, then exit-only from 16:30 to 18:30. Highway 8 between km 167.7 (Tianxiang) and km 184.5 (the Taroko entrance) opens in only five windows a day, at 06:30 to 08:00, 10:00 to 10:05, 12:00 to 13:00, 15:00 to 15:05, and 17:00 to 18:00, then exit-only from 18:00 to 18:30. Both halves close overnight from 18:30 until 06:30, so riding the east route at night is not an option. Between Guanyuan and Tianxiang there are further construction points at Dayuling, Guanyuan, Hualu Creek and Huoranting, each releasing traffic on its own schedule, so allow extra time for waiting. These controls are announced month by month and shift with the work, so check the notice for the month you are travelling rather than reusing an older one.
What a Support Vehicle Can Do for a Wuling Challenge
On a route with long distances, big elevation gain, and few support points along the way, a SAG (support and gear) vehicle earns its keep. 24EZGO has provided cycling race logistics since 2020, supporting 10 to 20 events a year, from KOM-style climbs to 197 km long-distance races, including Penghu island and Ironman events, serving over 3,000 riders and travelers.
On Wuling, the support vehicle follows the group, though in the eastern Zhongheng control zone it has to wait for the same release windows and cannot always be beside you. If you run out of steam, the weather turns fast, or altitude symptoms show up, you can get in and leave the route instead of pushing on alone at altitude. Supplies, cold-weather gear, and luggage ride in the vehicle, so you can climb light. The fleet has 4 support vehicles, each able to carry up to 8 riders and 8 bikes in a single run. For a solo challenge, a team training camp, or a trip built around an event like the Taiwan KOM Challenge, we plan around your group size, bike count, and days.
A Supported Wuling Day, Finished with Urn-Roasted Chicken
This west-side Wuling ride began in Puli, with the support van carrying bikes, luggage and the equipment needed around the day. The vehicle moved with the group along Highways 14 and 14A while each rider climbed at their own pace. If fatigue, weather or timing changed the plan, the group still had one coordinated way to move riders, bikes and bags together. The photos capture a support stop at Cuifeng, 2,309 meters above sea level, plus real bike checks and roadside logistics.
After the ride, the bikes were loaded and the group sat down at a local restaurant for Taiwanese urn-roasted chicken, or 甕缸雞. A meal stop is not automatically included in every booking, but it can be requested when planning. Send your date, group size, bike count, pickup and drop-off points, and whether you want a post-ride meal; we will confirm feasibility before providing a custom quote.
