Korea's best hot springs and spa towns: The ultimate guide 2026

For international travelers seeking the ultimate relaxation experience, Korea's hot spring culture offers a unique blend of therapeutic healing, historical significance, and modern luxury. While Japan is often the first country associated with onsen, Korea possesses a deep-rooted bathing culture (oncheon) dating back over a millennium, featuring water rich in germanium, sulfur, and alkaline minerals essential for skin health and stress relief.

The short answer: The best hot springs in Korea are Onyang (the oldest, used by kings), Yuseong (rich in radium), and Suanbo (natural 53°C water), while Busan’s Hurshimchung and Centum City Spaland offer the most impressive modern facilities for 2026.

Understanding Korean Bath Culture: Jjimjilbang vs. Oncheon

Before diving into the specific locations, it is crucial to understand the distinction between a Jjimjilbang and an Oncheon, a common point of confusion for first-time visitors.

A Jjimjilbang is a Korean dry sauna facility. While they have baths, the water is often heated tap water (unless located in a spring district). They focus on kiln saunas, relaxation areas, and sleeping rooms.

An Oncheon refers specifically to natural hot springs where the water comes from underground sources at temperatures above 25°C and contains specific mineral components regulated by Korean law. In 2026, there are over 450 designated hot spring protection zones across the peninsula.

Onyang Hot Springs: The Royal Retreat

Located in Asan, Chungcheongnam-do, Onyang Hot Spring is arguably the most historically significant thermal water site in Korea. Its history spans over 1,300 years, making it the oldest recording hot spring in the nation. It was a favorite retreat for Joseon Dynasty kings, including King Sejong the Great, who visited here to treat eye ailments and skin conditions.

The water at Onyang maintains a naturally high temperature of roughly 57°C (134°F). It is an alkaline hot spring, which is exceptionally gentle on the skin, making it popular for those with sensitive dermatological needs.

Getting There and Costs

Onyang is incredibly accessible from Seoul. You can take the Seoul Subway Line 1 directly to Onyang Oncheon Station, a journey that takes approximately 90 minutes from central Seoul and costs under ₩3,000. Alternatively, the KTX to Cheonan-Asan Station followed by a short taxi ride gets you there in under 45 minutes.

For families, the nearby Asan Spavis offers a more recreational approach. It combines the natural hot spring water with a water park environment, featuring slides and wave pools. Admission typically costs around ₩40,000 for adults during peak season, though discounts are often available for foreigners booking online.

Yuseong Hot Springs: The Healing Waters of Daejeon

If your itinerary takes you south, Yuseong in Daejeon is a must-visit. Legend says a wounded crane dipped its wing into the water here and was instantly healed. Scientifically, Yuseong's water is unique because it contains radium, which, in safe trace amounts, is believed to help with neuralgia and arthritis.

The water flows from 200 meters underground at temperatures ranging between 42°C and 55°C. The district is home to over 100 accommodation facilities, but the standout feature is the Yuseong Foot Bath Experience Park.

This open-air foot bath is completely free and accessible to the public 365 days a year. It is a fantastic spot to mingle with locals. We recommend visiting in the evening when the LED lights create a relaxing atmosphere under the zelkova trees. For a deeper soak, the Yuseong Hotel (operating since 1915) provides a classic full-body immersion experience for approximately ₩10,000.

Suanbo Hot Springs: The King's Water

Located in Chungju, North Chungcheong Province, Suanbo holds a special distinction: it is the only hot spring in Korea where the water quality is centrally managed by the city government, ensuring absolute purity. The water is drawn from 250 meters underground at a sizzling 53°C.

Suanbo is rich in lithium, calcium, and sodium, and the water is colorless and odorless. Unlike other spa towns that have become heavily commercialized, Suanbo retains a quieter, mountain-town vibe. It is particularly popular in autumn and winter.

If you are planning a trip during the colder months, Suanbo is an excellent stop after a day of activity. For those interested in combining physical activity with relaxation, check out our guide to autumn colors and hiking spots which features nearby Woraksan National Park.

Busan: The Tale of Two Spas

Busan offers a fascinating study in contrasts, presenting arguably the best "Dualism" spa experience in the country. You have the choice between the historic, massive scale of Hurshimchung and the ultra-modern luxury of Centum City Spaland.

Hurshimchung: The Legend

Located in the Dongnae district, famous for its alkaline waters since the Silla Dynasty, Hurshimchung is one of the largest hot spring complexes in Asia. The main skylight dome is iconic. The facility can accommodate 3,000 bathers simultaneously. The "Cave Bath" and "Longevity Bath" use 100% magnesium-rich spring water.

Spaland Centum City: The Modern Marvel

Located inside the Shinsegae Department Store (the world's largest), Spaland is the epitome of modern K-wellness. It draws two different types of hot spring water from underground: sodium bicarbonate and sodium chloride. It features 18 different themed saunas and an open-air foot spa.

For foodies visiting Busan, the area around Hurshimchung is famous for distinct local dishes. Before you go, read our Busan seafood guide to plan your post-spa meal.

Seorak Waterpia: Adventure Meets Relaxation

Located in Sokcho near the breathtaking Seoraksan National Park, Seorak Waterpia is unique because it uses 100% natural hot spring water for all its attractions—including the wave pools and water slides. The water here is cooled from 49°C and is rich in sodium, which helps soften the skin.

This is the premier destination for families. While the parents soak in the outdoor "Spa Valley" with views of the snow-capped Seorak mountains, children can enjoy the slides. The resort underwent a major renovation in 2023, adding more private spa zones.

The distance from Seoul is about 2.5 hours by car or bus. We highly recommend visiting in winter. The sensation of hot water meeting freezing mountain air is unforgettable.

Paradise City Cimer: The Instagram Icon

While not a traditional "town," Cimer at Paradise City in Incheon deserves mention for redefining the Korean spa experience. Located just 10 minutes from Incheon International Airport, it is a fusion of European spa culture and Korean Jjimjilbang.

Cimer is divided into the Aqua Spa Zone (infinity pools, LED slides, virtual spa) and the Jjimjil Spa Zone. It is less about mineral healing and more about visual luxury and relaxation. It is an adult-focused facility (children under 10 are generally not allowed).

Since this is near the airport, travelers often debate between transportation options. Check our guide on Airport Limousine Bus vs AREX to get there efficiently.

Jeju Sanbangsan Carbonate Hot Springs

Jeju Island offers a rare geological treat: carbonated hot springs. Located on the southwest coast, the Sanbangsan Mountain Carbonate Hot Springs feature water that bubbles with free carbon dioxide.

When you first enter, the water feels cool, but as the carbon bubbles stimulate your capillaries, your body temperature rises, and you feel a distinct warmth. This "soda water" is famously beneficial for hypertension and heart conditions.

The outdoor pools offer a majestic view of Mt. Sanbangsan. The entrance fee is reasonable, generally around ₩13,000, with an extra charge for the open-air bath.

A Step-by-Step Guide to Korean Spa Etiquette

For many Western travelers, the nudity aspect of Korean spas can be daunting. Here is exactly how to navigate the process so you look like a pro.

The "Seshin" (Body Scrub) Experience

While at these spas, you will see locals lying on plastic tables getting scrubbed by staff wearing black underwear. This is Seshin. For a price between ₩25,000 and ₩40,000, they will exfoliate every inch of your body using a rough viscose mitt. It is intense, slightly embarrassing for first-timers, but leaves your skin incredibly soft.

After a deep scrub, hydration is key. Read our complete guide to the Korean skincare routine to see how to maintain that glow after you leave the spa.

Pricing and Budgeting for Your Spa Trip

Hot spring prices in Korea are generally very affordable compared to Europe or Japan. Here is a breakdown of what to expect in 2026.

Pro Tip: Most designated hot spring areas have "motels" or smaller hotels that pipe the same spring water into the guest room bathtubs. If you are too shy for the public bath, booking a room in the Onyang or Suanbo area (approx. ₩60,000/night) allows you to soak in private.

Best Time to Visit

While spas are open year-round, the experience differs by season.

• Winter (Dec-Feb): The peak season. Nothing beats the contrast of cold air and hot water.
• Spring/Autumn: Ideal for combining hiking with bathing.
• Summer: Water parks like Seorak Waterpia are crowded, but traditional indoor hot springs are surprisingly quiet.
