No sulphur smell. No cloudiness. No residue. Just sodium bicarbonate at 58°C that leaves your skin noticeably silky — and explains why Taipei residents board a train every winter weekend to cross the mountains into Yilan. This guide covers everything: getting here, the four ways to soak, the five hotels we actually reviewed, free options, etiquette, and where to eat scallion pancakes afterwards.



If you have ever soaked at Beitou and found the sulphur smell too much — or you are simply curious what a hot spring feels like when the water looks completely transparent — Jiaoxi (礁溪) is the answer. The springs here are sodium bicarbonate type, pH-neutral at 7–7.8, emerging from the ground at around 58°C. The water is clear, carries no detectable odour, and when you climb out of the bath your skin feels smooth without any sticky residue. That is why Taiwanese call these springs 美人湯 — Beauty Spring.
Jiaoxi's hot spring culture dates to the Japanese colonial era around 1907, when the springs were discovered and the first public bathhouses established. For decades it remained a slow day's journey from Taipei. Then the Hsuehshan Tunnel opened in 2006, cutting the road trip to under an hour. Today Jiaoxi is Taipei's most popular weekend escape and easy day-trip for hot spring enthusiasts, with hotels ranging from NT$2,800-a-night budget rooms to NT$15,000+ cypress-bath suites.
Both options are easy. The train wins on speed and reliability; the bus wins on price and frequency.
Best Season: Winter (November–February) is peak hot-spring season. Cool air makes the warm water feel genuinely restorative, steam rises beautifully, and many hotels discount midweek stays. Summer soaks work best in early morning or evening. Typhoon season runs July–September — check forecasts before travelling.
Jiaoxi covers every budget and preference — here is how each option works in practice.
The first stop for almost every visitor — free public foot-spa channels set into the pavement of a leafy park, open around the clock. Sit on the edge, remove your shoes, and let Jiaoxi's famous sodium bicarbonate water do its quiet work on tired feet.
No equipment needed, no charge, no queuing system. Just 5–7 minutes from Jiaoxi Train Station on foot. A perfect way to taste the water before committing to a hotel.
Jiaoxi's open-air public hot-spring pool, where swimwear and a swim cap are required — making it the most family-friendly option. Entry is just NT$80 and children are welcome. Set in a natural outdoor setting rather than a hotel interior, the atmosphere is relaxed and unpretentious.
Located around 3 km from Jiaoxi Station — a short taxi ride. Ideal for anyone who prefers mixed-gender soaking with clothing.
Several mid-range and five-star hotels maintain large gender-separated communal baths in the traditional Japanese style — no swimwear, clean shared pools. For hotel guests the bath is usually included; non-guests can buy a day-use pass for around NT$300–800.
Hotel Royal Chiao Hsi is particularly well regarded for its large, immaculately clean shared facility with continuously refreshed water.
The most comfortable way to experience Jiaoxi — a private soaking tub in your own room, available at any hour of night or day. Some rooms feature cypress-wood tubs whose natural fragrance mingles with the mineral water; others use stone or porcelain.
Yamagata Kaku (rated 9.6) is celebrated for its cypress in-room baths — an experience that is genuinely difficult to replicate anywhere else in Taiwan. Book the right room type when reserving.

A full Japanese kaiseki 5-star experience — every room includes a private cypress-wood soaking tub whose subtle timber scent transforms a hot spring bath into something genuinely meditative. Multi-course kaiseki dinners served in-room or in the restaurant.
The established flagship of Jiaoxi — offers both a large shared public bath (separate gender) and rooms with private in-room tubs. Professional staff, comprehensive facilities, and a solid reputation make this the safe choice for families and couples wanting reliability alongside comfort.
Generous grounds, large hot-spring pools, a swimming pool, and varied activities make this the most family-friendly resort in Jiaoxi. Multiple room sizes accommodate groups well. The resort feel — open space, easy parking, multiple dining options — suits those who want more than just a soak.
Silks Group's wellness-focused boutique property — the soaking spaces are beautifully designed, intimate, and conceived around the ritual of water rather than just the plumbing. An excellent middle path between the scale of Hotel Royal and the price of Yamagata Kaku for couples who care about aesthetics.
Silks Group's three-star label brings in-room private hot-spring tubs to every single room — genuinely remarkable for the price. Clean contemporary design, great location near the station, no communal pool. The honest choice for anyone who wants a private onsen without spending more than NT$3,500.
Jiaoxi hotels fill quickly on winter weekends and holidays — book at least two to four weeks ahead during peak season. Use Agoda for hotel rooms or Klook for packaged hot-spring experiences.
Avoid soaking or consult your doctor first if you: have eaten a heavy meal within the past hour · have a fever · have poorly-controlled high blood pressure · are pregnant · are accompanying a child under 3 years old. Jiaoxi water is gentler on skin than sulphur springs, but the heat of 50–58°C still puts demand on your heart and circulation.
Jiaoxi and the Yilan plains are famous across Taiwan for producing exceptionally flavourful scallions — the volcanic soil and rainfall create an onion with deeper, sweeter notes than anywhere else on the island. The most popular expression is scallion pancake (蔥油餅): unleavened dough pan-fried with a generous handful of chopped spring onion, served crisp outside and tender within.
Dozens of stalls cluster around Jiaoxi Station and along the main shopping street. Most open from midday through late evening — easy to grab after a long afternoon soak.
Yilan faces the Pacific — fresh seafood arrives daily at prices that feel improbably reasonable to visitors from Taipei. Prawns, oysters, crab, and whole steamed fish are the highlights. Look for restaurants around Jiaoxi's market streets or, if you have time, take a short taxi to the coastal fishing villages.
If staying overnight, the Luodong Night Market (羅東夜市) is around 15 minutes by taxi and combines local seafood with the full breadth of Taiwanese night-market snacking — a worthy second act to the hot spring.
