The Wai-an Line (route number 0758, sign “21”) is an urban bus route operated by the Penghu County Public Transportation Authority. It departs from Magong Main Station, crosses central Magong, then heads west along County Road 203 through Huxi Township (Xujia, Dingwan, Tanbian) and into Baisha Township (Zhongtun, Jiangmei, Zhenhai, Gangzi, Chikan, Houliao, Tongliang). From there it crosses the Penghu Bay Bridge — approximately 2,494 metres long — into Xiyu Township, terminating at Wai-an Fishing Port on the southwestern tip of the island. The standard service (route 21) covers 83 stops, making it the longest Penghu island bus route with the highest concentration of scenic stops, and the only public bus option for visitors exploring Xiyu without a scooter rental.
Route Highlights
The Wai-an Line’s main appeal is that a single journey links nearly every major attraction in Xiyu Township:
- Tongliang Banyan: A banyan tree over 300 years old whose canopy spans the forecourt of Bao’an Temple — one of Penghu’s most recognizable natural landmarks. The bus terminates at “Tongliang Banyan Terminal Station.”
- Penghu Bay Bridge: The long sea bridge connecting Baisha and Xiyu offers open views from the roadway. The bus stops at “Penghu Bay Bridge Station” and “Bridge Head Station” on each end, letting passengers choose their preferred vantage point.
- Xiaomen Whale Cave: A basalt sea cave on the northern tip of Xiyu, named for its whale-shaped opening. Most trips loop through Xiaomen Archway and stop at “Xiaomen Whale Cave Station”; some do not — confirm before boarding.
- Erkan Old Settlement: A well-preserved settlement of Qing-dynasty Minnan-style courtyard houses, now a heritage tourism area. The bus stops at “Erkan Old Settlement Station,” within easy walking distance of the village.
- Xitai Fort: The remains of a Western-style artillery battery built during the Qing dynasty under Liu Mingchuan. The bus stops at “Xitai Fort Station.”
- Wai-an Fishing Port: The fishing village at the southwestern tip of Xiyu, known for its lantern-lit harbor at night and its sunsets. The terminal stop is near the harbor area.
Some trips also loop through Zhuwan Dayi Temple (Zhuwan Dayi Temple Station) and Zhuwan Fishing Harbor, or extend toward Qitou, so the same direction of travel may show several different stopping sequences in the timetable — this is normal and not a data error. The privately operated Penghu Aquarium (No. 58, Qitou Village, Baisha Township; 06-9933006) has been open continuously since its 2018 reopening; if visiting, check whether your specific trip routes via Qitou or plan to alight at the nearest Qitou intersection and walk into the village.
Stop-by-Stop Overview
Magong Urban Segment (Magong Main Station → Dongwei Station, stops 1–11): Leaving Magong Main Station, the bus first loops past Huimin Hospital and Beichen Market (a traditional local market best for fresh produce in the early morning), then continues along Yangming Station, Cultural Center Station, and Magong Senior High School Station heading east, passing the Penghu Branch of the High Court, Taiwan Power Company Station, and Tianxiang Station before reaching Dongwei Station. This stretch is the core commuter corridor for Magong residents travelling to work, medical appointments, and shopping. Magong Main Station is about a 10-minute walk from Tianhou Temple and the Four-Eyed Well; travelers with a tight schedule can explore the old town before boarding.
Baisha Rural Segment (Xujia → Tongliang Banyan Terminal, stops 15–44): After Dongwei, the bus heads west through Xujia South Station, Xujia Station, and Xujia North Station, entering the southern edge of Huxi Township, then continuing north into Baisha Township. It passes Zhongtun Elementary School (Zhongtun’s wind turbine stands right along the roadside), Jiangmei Station, and Jiangmei Longde Temple, then pushes through the fishing villages of Chikan, Gangzi, and Houliao. This stretch is dense with settlements and temples; the bus is also the primary transport link for elderly residents visiting clinics and children commuting to school. The most important stop before the terminal is Tongliang Banyan Terminal Station (stop 44), where many visitors alight to see the 300-year-old banyan before catching the next service across the Penghu Bay Bridge.
Deep Xiyu Segment (Penghu Bay Bridge → Wai-an Terminal, stops 45–83): After crossing the bridge into Xiyu Township, the bus stops at Bridge Head Station and Hengjiao Station, then follows the west coast of Xiyu southward. Depending on the trip, it loops through Zhuwan Dayi Temple, Zhuwan Fishing Harbor, Xiaomen Archway, and Xiaomen Whale Cave, then passes Dachi and Erkan Outer Station, stopping at Erkan Old Settlement Station (stop 65) before continuing south through Xiyu Health Center, Chima, Xiyu Library, and Neian, then stopping at Xitai Fort Station (stop 78), followed in sequence by Wai-an Police Station, Wai-an Elementary School, Wai-an West Station, and Wai-an East Station, finally arriving at Wai-an Terminal (stop 83).
Nearby Attractions
Around Magong Main Station: Allow time before departure to explore Magong’s old town. Tianhou Temple is one of the oldest Mazu temple complexes in Taiwan, closely connected to the Four-Eyed Well (a Qing-era four-hole brick well) and the century-old Zhongyang Old Street — all three can be visited on foot in 15–20 minutes. Continue another 20 minutes along Zhongshan Road to reach Guanyinting, a seafront promenade and one of Penghu’s most popular spots for watching sunsets, and also the main venue for the annual Penghu International Ocean Fireworks Festival. In 2026 the festival runs from 4 May to 25 August, with shows at Guanyinting every Monday and Thursday in May–June (shifting to Tuesdays from July), starting at 9:00 PM; confirm the full schedule via the Penghu County Tourism Bureau before your visit.
Suggested itinerary along the route: Alight at Tongliang Banyan Terminal Station to visit the ancient banyan and Bao’an Temple, walk to the bridge approach for a view of the Penghu Bay Bridge, then catch the next bus to Zhuwan Dayi Temple Station, followed by Xiaomen Whale Cave Station to see the sea cave, then continue to Erkan Old Settlement Station to stroll through the heritage courtyard houses, and finally ride to Wai-an Terminal for a harbor sunset. The full multi-stop day requires careful use of the return timetable — the last bus from Wai-an back to Magong departs at 20:40, so plan accordingly before heading out.
Commuter Rhythm
The first section of the route passes schools and government offices throughout central Magong — Magong Senior High School, Dongwei, Zhiqing Junior High School, Zhongtun Elementary School, and Houliao Elementary School all have dedicated stops, and morning and evening services are used mainly by local students and residents. Beyond Tongliang Banyan and the Penghu Bay Bridge, passengers are predominantly tourists. Because the one-way journey from Magong to Wai-an takes around 80–95 minutes along winding roads in Xiyu, passengers prone to motion sickness are advised to take medication before boarding.
When to Travel
The Wai-an Line operates approximately 12–13 trips per direction per day. First departure from Magong: 06:55 (service 21); last departure: 21:40 (service 21K). First departure from Wai-an: 06:20 (service 21L); last departure: 20:40 (service 21J). TDX data shows identical weekday and holiday schedules.
Note: Service 21N (outbound 15:30, return 17:00) — TDX ServiceDay shows this service scheduled every day of the week; for confirmation of any given week’s actual operation, call the Penghu County Public Vehicles Administration on 06-9213822 before relying on this trip. During peak tourist season, consider the 09:40 departure (21B) or 10:40 departure (21C) from Magong to arrive at Xiyu attractions by midday; for the return, the 16:00 (21F) or 18:00 (21H) service gets you back to Magong in time for dinner.
- Summer (June–September, peak season): Visitor numbers are high at Baisha and Xiyu attractions, especially at Tongliang Banyan and the Penghu Bay Bridge viewpoints around midday. An early departure (08:55 or 09:40) with an afternoon return (16:00 service) avoids the peak crowds while still allowing time to watch the sunset at Wai-an before the last bus.
- Winter (October–March): The northeast monsoon brings strong winds; gusts on the Penghu Bay Bridge frequently reach Beaufort force 7, and conditions near Wai-an Fishing Port can be rougher still. Some attractions along the route shorten their hours or close temporarily in winter — check current hours before setting out and bring a windproof jacket to wear while waiting at stops.
