Keelung to Chiayi Road Trip Guide: Best Stops & Routes

Starting in the rain-soaked port city of Keelung, the drive to Chiayi in Taiwan's central-southwest spans roughly 250 kilometers along the Sun Yat-sen Freeway (National Highway 1). This route cuts through the island's western corridor, passing the Taoyuan plateau, Hsinchu's wind-blown plains, and the agricultural heartland of Changhua before descending into Chiayi's subtropical basin.

The journey itself is a study in contrasts: from Keelung's humid, monsoon-lashed coast to Chiayi's sunnier, drier climate, with the mountains of the Central Range looming to the east.

Historically, this corridor was part of the old north-south road used during the Qing dynasty, but today it is a modern, well-maintained freeway system. The average driving time is about 3 hours and 20 minutes without traffic, but plan for 4 to 5 hours with rest stops.

Infrastructure safety is top-notch: the freeway is well-lit in urban sections, has concrete barriers, and emergency telephones every 1 km. Speed limits range from 100 km/h on flat sections to 80 km/h in mountainous curves.

For families, the route is replete with child-friendly stops. Leofoo Village Theme Park near Hsinchu is a full-day adventure, while the Taichung Science Museum offers engaging exhibits for older kids.

Pet-friendly framework: most highway rest areas allow pets on leashes in outdoor spaces, and there are designated pet relief areas at major service stations like Hukou and Xihu. Some hotels in Chiayi welcome pets, but check in advance.

To manage fatigue, plan to stop every 2 hours. The Xihu rest area is known for its spacious green areas for stretching, and the Houli rest area near Taichung has walking paths.

For things to do between Keelung and Chiayi, don't miss the off-route Gemimu Farm in Cingshuei, near Taichung, where you can see sunflowers and other seasonal blooms.

The landscape evolves from Keelung's rugged coastline to the fertile plains of central Taiwan. Near Miaoli, the hills are covered with tea plantations, and Taichung's metropolitan area gives way to sunflower fields and rice paddies as you approach Chiayi.

Along NH1, the most notable natural attraction is the Longteng Bridge at Sanyi, a historic railway bridge set in a green valley.

Local commerce thrives at exit interchanges: in Taoyuan's Daxi, you can buy takan (black tea) and dried tofu; in Hsinchu the famous rice noodles and meatballs are must-tries; and around Taichung, stop for suncakes and pineapple cakes.

The best stops Keelung to Chiayi include these market towns, each offering a taste of regional culture.

For a UNESCO World Heritage Site, you could divert to the Mazu temples at Beigang, but the only official UNESCO site on the island is the Taiwan Tropic of Cancer marker at Shuishang, just south of Chiayi city.

National Highway 1 is the primary artery, but an alternative is the more scenic National Highway 3 (Formosa Freeway) that swings east through mountainous terrain. The drive on NH1 is generally faster, yet NH3 offers better views and lighter traffic.

Fuel costs vary, with prices around NT$30 per liter. The route is densely supplied with gas stations, especially around Taoyuan, Hsinchu, and Taichung.

The road quality is excellent: well-paved, clearly marked, and equipped with modern safety features. Toll fees are collected electronically via the eTag system, and total tolls for a one-way trip amount to roughly NT$300.

• Highway rest areas occur every 50-80 km, with major ones at Zhongli, Hukou, and Xihu.
• All rest areas provide fuel, food, restrooms, and convenience stores.
• Road conditions are updated on the 1968 app for real-time traffic.
