Kaohsiung to Keelung: A Road Trip Guide

National Highway 1 (Sun Yat-sen Freeway) links Kaohsiung (the south's industrial port) with Keelung (Taiwan's northern harbor) across 373 kilometers of the western corridor. Completed in 1978, it was Taiwan's first freeway, and its route traces the island's most heavily urbanized belt, passing through historic cities like Tainan and Taichung.

Driving straight through takes about 4.5 hours without traffic, but the journey rewards those who leave the freeway.

Road quality is excellent; fatal accidents are rare, but speed cameras are frequent. The freeway speed limit is 100-110 km/h; heavy fines for violation. For families, rest areas like the Xihu Service Area (Miaoli) have playgrounds, and it's common to see parents with strollers. Pets are allowed in service areas but must be leashed; some have designated pet relief areas.

For fatigue, Taiwan's freeway system mandates a rest stop every 50 kilometers. Try the "15-minute nap" at a service area—most have shaded parking. Hidden off-route spots: for a quiet coastal detour, take Exit 33 at Dajia to visit the Dajia Jenn Lann Temple and its nearby beach, or at Exit 108, the Nanzhuang Old Street offers a mountain village escape.

Local commerce thrives along the route; small stalls selling pineapple cakes (in Taichung) and oyster omelets (in Tainan) abound. For planning, use how to find the best stops and hidden gems between cities. is it worth driving Kaohsiung to Keelung? Absolutely, for the freedom to explore.

The fastest route is National Highway 1, but National Highway 3 (Formosa Freeway) offers a more scenic inland alternative, though it's 40 kilometers longer. Tolls are distance-based, averaging about NT$1.2 per kilometer, so the trip costs roughly NT$450 each way. Electronic toll collection (eTag) is mandatory; rental cars come equipped, and you can pay at convenience stores within 3 days.

• Fuel: Highway 1 has 13 service areas with gas stations, roughly every 30 kilometers.
• Diesel: More common for trucks; petrol cars generally use 92, 95, or 98 octane unleaded, all available.
• EV charging: Fast chargers at most service areas; recommend planning stops via the iCHARGE app.

Geologically, the route runs along the flat coastal plain, with the Western Foothills rising to the east. The climate shifts from tropical in Kaohsiung (average 27°C year-round) to subtropical in Keelung (19°C), often noticeably cooler and rainier in the north—pack accordingly: light clothing for the south, a rain jacket for the north.

UNESCO World Heritage Sites are scarce on this corridor; the nearest is the village of Chenkung in Taitung, far off-route. However, cultural gems like the Lukang Longshan Temple (18th century) offer historical depth without UNESCO status.

Highway 1's service areas are more than rest stops—they double as local markets. For example, the Dongshan Service Area in Yilan (via Highway 5) is a foodie magnet, but along Highway 1, the Tai'an Service Area features native produce and pastries. If you crave authentic night markets, exit at major cities: Kaohsiung's Liuhe Night Market or Keelung's Miaokou Night Market.
