덕구온천
A natural hot spring deep in the mountains of Uljin.
First bathhouse? Scrub Pass →About this place
NotesDeep in Uljin, it's hard to reach, but worth the journey. Soaking quietly in an outdoor bath surrounded by nature. Don't expect fancy facilities — but if you want to feel the essence of a real hot spring, this is the place. The main oncheon hall is gender-separated. Its centerpiece is a hot bath fed with 42.4°C spring water used exactly as it comes up, neither heated nor cooled, alongside a bagaji bath where you ladle the gushing water over yourself. There's a cold plunge as well. Saunas — amethyst sauna, jade sauna and an amethyst gem heated bed — are installed on both the men's and women's sides. Spa World is the mixed-gender zone, so a swimsuit and swim cap are mandatory. A 42°C panoramic outdoor bath anchors it, joined by a lemon bath, a hinoki wood bath, an event bath with rotating additives, the Terra Aqua hydrotherapy area, the jet-stream Action Spa, and a kids pool with a slide. An outdoor sun deck, the Hwangok deck and an 800-capacity locker room round it out. The main hall costs 11,000 KRW for adults and 8,000 KRW for children; Spa World is 26,000 KRW weekdays, 32,000 KRW weekends, 38,000 KRW in peak season. Resort guests pay 6,500 KRW for the oncheon and get 40–50% off Spa World. Child rates cover ages 24 months to elementary school, and under 24 months is free with proof. The two zones close at different times: the main hall runs 06:00–22:00, while Spa World shuts at 19:00 on weekdays and 20:00 on weekends and holidays. Private spa rooms book in 2- or 3-hour blocks from 60,000 KRW (standard) and 96,000 KRW (premium), walk-in inquiry only, no advance reservations. Open year-round, with free parking for around 2,000 cars.
Practical notes
Swimwear and a swim cap are mandatory in Spa World. The private spa rooms cannot be booked ahead — ask at the desk on the day.

No booking needed
Just walk in
Places like this do not take bookings. Pay at the counter and go in. Know the steps below and a first visit is fine.
From the door to the exit
- Pay the entry fee at the counter. Many take cards, but a little cash is the safe bet. You get a shoe-locker key.
- Put everything in a locker in the changing room. The bath area is fully nude — no swimwear. Wear the key on your wrist.
- Shower before entering any tub. This is the one rule everyone notices.
- For a body scrub (seshin), go straight to the scrub attendant inside the bath area. Usually cash, and you wait your turn.
- Return the key at the counter on the way out. Some places settle extras (scrub, drinks) at that point.
Good to know
- Men and women bathe separately. In jjimjilbang common areas you wear the provided sauna clothes.
- Large tattoos may be refused at some places. If that concerns you, check before you go.
- A towel is usually provided but small. Scrub mitts, toothbrushes and razors are sold at the counter.
- No photos inside the bath area. Easiest to leave your phone in the locker.
- Prices and hours are compiled from public information and may have changed. If you are coming from far, one phone call is worth it.

Private scrub rooms are one-to-one, bookable, and run on a fixed time slot. If a public bath feels unfamiliar, this is the easier route.
