After a full day of walking Seongsu-dong’s streets, doing workshops, and eating well, there’s one more thing the neighbourhood does better than almost anywhere else in Seoul: it lets you properly unwind. The Seongsu-dong spa and wellness Seoul scene is anchored by one standout option — THE FORET SPA at Seoul Forest Station — and it’s the kind of place that makes you reconsider your entire relationship with rest. I’ve ended more Seongsu-dong days here than I can count, and I’ve never once regretted it.

Korean Spa Culture: What to Know First
Korean spa culture — the jjimjilbang tradition — is one of those things that sounds intimidating until you actually experience it. The concept is simple: a large communal bathhouse with multiple sauna rooms at different temperatures, hot and cold pools, relaxation areas, and often food and drink facilities. You pay a flat entry fee, change into the spa’s provided clothing, and spend as long as you like moving between the different spaces.
What makes Korean spas different from Western equivalents is the communal nature of the experience. You’re not in a private room with a treatment table. You’re in a shared space with other people, all in the same spa clothes, all doing the same thing. For visitors who haven’t experienced this before, it can feel unfamiliar at first. Within about twenty minutes, it feels completely natural.
The health benefits of the jjimjilbang experience are well-documented in Korea: improved circulation, reduced muscle tension, better sleep, and a genuine sense of mental decompression. After a day of walking and workshops in Seongsu-dong, the physical benefits are immediately noticeable.

THE FORET SPA: Full Review
THE FORET SPA is located at Seoul Forest Station on the Bundang Line — one stop from Seongsu-dong, or a 15-minute walk through Seoul Forest. The location is deliberate: the spa is designed to feel like an extension of the forest, and the architecture and interior design lean into that connection heavily.
The facility includes multiple sauna rooms (dry heat, infrared, charcoal, and salt), hot and cold pools, a rooftop relaxation area with views over the forest, and a range of body treatment options available as add-ons. The standard entry gives you access to all the sauna rooms and pools. The rooftop area is the highlight — wooden loungers, warm afternoon light filtering through the trees, and a level of quiet that’s genuinely rare in Seoul.
I’ve been to THE FORET SPA in every season, and it’s good in all of them. In spring, the rooftop is surrounded by cherry blossoms. In summer, the cold pool is the best thing in the city. In autumn, the forest views are extraordinary. In winter, the heat of the sauna rooms against the cold outside air creates a contrast that’s deeply satisfying.
The staff are professional and the facilities are well-maintained. The spa is popular with both locals and visitors, and it can get busy on weekends — booking in advance is strongly recommended.

What to Expect at THE FORET SPA
Arrival and check-in. You’ll receive a locker key, a set of spa clothes (shorts and a t-shirt in the spa’s signature colour), and a towel. Change in the locker room and leave your belongings securely.
The sauna circuit. Most visitors spend their time moving between the different sauna rooms and the pools. A typical circuit might be: 15 minutes in the dry sauna, a cold shower, 10 minutes in the infrared room, a rest in the relaxation area, then the hot pool. There’s no right or wrong order — follow what feels good.
The rooftop. This is the highlight of THE FORET SPA. Take your time here. The wooden loungers are comfortable, the views are beautiful, and the combination of warm spa-relaxed muscles and cool outdoor air is one of the best feelings available in Seoul.
Body treatments (optional). THE FORET SPA offers a range of additional treatments — body scrubs, massages, and facial treatments — that can be booked as add-ons. The Italian towel scrub (italy towel exfoliation) is a Korean spa classic and worth trying if you’ve never experienced it.
Food and drink. The spa has a small cafe area where you can get drinks and light snacks. The classic Korean spa snack — sikhye (sweet rice punch) and a hard-boiled egg — is available and genuinely delicious after a sauna session.

Tips for First-Time Spa Visitors
Hydrate before you go. Sauna sessions cause significant fluid loss. Drink water before your visit and use the water stations inside the spa regularly. Dehydration in a sauna is unpleasant and avoidable.
Don’t eat a heavy meal immediately before. A light meal or snack is fine. A full Korean BBQ feast followed immediately by a sauna session is not comfortable. Give yourself at least an hour after eating before you start the sauna circuit.
Bring nothing valuable. The lockers are secure, but there’s no reason to bring anything you’d be upset about losing. Phone, wallet, and key — everything else can stay at your accommodation.
Take your time. The temptation for visitors is to rush through the sauna rooms and leave after an hour. Resist it. The jjimjilbang experience is designed for slow, extended use. Three to four hours is ideal. The longer you stay, the more you get out of it.
Combine with a full Seongsu-dong day. THE FORET SPA works best as the final stop on a full Seongsu-dong day. Do your workshop in the morning, eat well at lunch, explore the neighbourhood in the afternoon, and end at the spa.

FAQ
Is THE FORET SPA suitable for first-time jjimjilbang visitors?
Yes. THE FORET SPA is one of the more visitor-friendly Korean spas in Seoul. The facilities are modern and well-maintained, the staff are accustomed to international guests, and the booking process through Klook includes clear instructions on what to expect. If you’ve never been to a Korean spa before, this is an excellent introduction.
What should I bring to THE FORET SPA?
Very little. The spa provides towels, spa clothes, and all the facilities you need. Bring a change of underwear for after your visit, any personal toiletries you prefer (though the spa has basics available), and a small amount of cash or a card for add-on treatments or food. Leave valuables at your accommodation.
Can I visit THE FORET SPA without booking in advance?
Walk-ins are sometimes possible on weekdays, but weekends are often fully booked. Booking through Klook in advance is strongly recommended, particularly if you’re visiting on a Saturday or Sunday or during Korean public holidays.
How long should I plan to spend at THE FORET SPA?
A minimum of two hours, ideally three to four. The sauna circuit, rooftop time, and relaxation areas reward slow, extended use. If you’re adding a body treatment, factor in an extra hour for that.
Is THE FORET SPA mixed-gender?
The common areas (sauna rooms, relaxation areas, rooftop) are mixed-gender, with spa clothes provided. The changing rooms and bathing areas are gender-separated. This is standard for Korean jjimjilbang facilities.
My Thoughts
I’ve been going to Korean spas since I was a child, visiting relatives in Seoul during school holidays. The jjimjilbang was always the place where the day slowed down — where the adults stopped rushing and the children stopped asking questions and everyone just sat in the heat together.
THE FORET SPA has that same quality, even though it’s a modern facility rather than a traditional neighbourhood bathhouse. There’s something about the combination of heat, rest, and the sound of the forest outside that creates a particular kind of quiet that’s hard to find anywhere else in Seoul.
If you’re visiting Seongsu-dong and you skip the spa, you’re leaving the best part of the day on the table.
